Thanks - Torque springs - arrived quickly and good quality - Fast service - Always have the items i need and they come relatively fast! - Excellent - We recently purchased a 30-year old hydroseeder and have no manuals or parts diagrams for it. The manufacturer is since out of business and there is very limited information on line. The most critical part we needed was a Dodge part. The original part was clearly marked with the Dodge name and part number. MRO was quickly able to identify the replacement part and we had in hand in two days. Perfect fit. Thank you MRO Supply for helping make our machine functional. ## FAQ: - How do I keep water out of a bearing on a wet shaft (washers, washdown conveyors)?: Three factory-recommended angles: a more robust multi-lip seal option for the housing where one exists; Dodge's modern SAF-style mounted bearing, which installs faster than a traditional SAF assembly and seals better; and continuous lubrication with an automatic lubricator (IntelliLube), which keeps a positive grease purge at the seal so water is pushed out instead of drawn in. - Which Dodge bearings hold up on sand-and-gravel conveyors with regular washdown?: Dodge's Harsh Duty series (formerly the Defender series) was designed for aggregate duty. It's a seal upgrade over the standard product with identical mounting dimensions, so it drops into your existing footprint: Harsh Duty versions exist for Type E and TAF tapered-roller pillow blocks and for ball bearings (ED suffix). The tapered line carries a one-year performance guarantee against solid-particle-contamination failure when commissioned with a Dodge IntelliLube automatic lubricator. - What grease do Dodge bearings come with from the factory?: Standard Dodge mounted bearings ship shaft-ready with an NLGI #2 lithium-based grease. Ball bearing inserts are factory-filled with Mobil Unirex N2 (a lithium complex grease); roller bearings get a heavier grease, Mobil XHP 222. Bearings can also be ordered dry, or with a special grease, if your plant runs its own lubrication standard. - How much grease is in a Dodge bearing out of the box?: Most standard Dodge bearings ship with a 33–35% factory grease fill. Washdown bearings ship 100% full; Harsh Duty ball bearings ship at 66%. All are shaft-ready out of the box — no pre-lube needed before installation. - How does Dodge warranty evaluation work if a product fails?: Failed units go to Dodge's US plants for evaluation — about a week in transit plus one to two weeks of analysis, and you get the findings either way. Warranty covers workmanship and material defects; failures caused by the application (lubrication, installation) fall to the customer, but the failure analysis tells you the root cause so it doesn't repeat. - How can I tell if my 2-bolt pillow block needs replacement?: Watch for excessive heat, unusual grinding or squealing noise, or visible vibration during operation, which often indicate misalignment or insufficient lubrication. Verify shaft alignment with a laser tool and check grease condition before replacing the unit, as these are common causes of premature failure. - What's the proper installation procedure for 2-bolt pillow blocks?: Slide the bearing onto the shaft and use a rubber mallet with a hardwood block to gently tap it into position—never strike the housing or seals directly. Once aligned, secure both mounting bolts firmly to the mounting surface while ensuring the shaft remains parallel and properly aligned. - How often should I re-lubricate 2-bolt pillow blocks?: Most 2-bolt pillow blocks ship pre-packed with NLGI #2 lithium complex grease and require re-lubrication roughly every 2 months when operating at 1,000 RPM and 150°F. At lower speeds or cooler conditions, re-lubrication intervals can be extended; always use a grease compatible with the original lubricant family to avoid compatibility issues. - What sizes are available for 2-bolt pillow block bearings?: 2-bolt pillow block bearings are available with shaft bore diameters ranging from 1/2" to 4", with standard duty models typically handling RPM ratings between 2,500 and 3,000. Common sizes include 1-3/4", 2", 2-3/16", and 3-1/8" bores for most general industrial applications. - What load capacity should I expect from a 2-bolt pillow block?: Load capacity varies significantly by bore size and duty rating; standard duty models typically carry lower radial loads compared to medium or heavy-duty variants of the same size. Consult the manufacturer's datasheet for your specific bore size to confirm the dynamic and static load ratings for your application. - Are pillow block bearings pre-lubricated, and how often should they be re-lubricated?: Pillow block bearings are supplied pre-greased and sealed, requiring no lubrication at startup. Under standard operating conditions, occasional re-lubrication with light machine oil (every 6–12 months) or per manufacturer guidelines is sufficient; sealed designs minimize maintenance compared to open-style housings. - How much misalignment can a pillow block bearing tolerate?: Most pillow block bearings with spherical roller designs allow up to ±2–3° of angular misalignment to accommodate minor shaft deflection and installation tolerances. This angular freedom makes them ideal for machinery where perfect alignment is difficult to achieve, such as conveyor systems and pump shafts. - What is the difference between a pillow block bearing and a loose bearing?: A pillow block bearing is a complete mounted assembly with the bearing pre-installed in a housing frame ready for shaft mounting, while a loose bearing is the bearing component alone. Pillow blocks provide simplified installation, self-alignment up to ±2°, and bolt-down convenience for machinery support applications. - What are typical bore sizes available for pillow block bearings?: Pillow block bearings are commonly available in metric bore sizes ranging from 12mm to 75mm, with popular series like UCP200 complying to ISO 113 boundary dimensions. Common smaller sizes (UCP201–UCP204) handle 12–20mm shafts, while larger sizes (UCP210–UCP215) accommodate 50–75mm shafts for heavy industrial applications. - What materials are used in pillow block bearing housings?: Pillow block housings are typically constructed from ductile iron or steel stampings, with internal bronze or steel liners and neoprene or elastomer flex layers that absorb vibration and dampen shaft movement. The housing design provides both structural rigidity and vibration isolation for long bearing life in industrial equipment. - How do I install a mounted bearing correctly?: Verify your shaft diameter is within the bearing bore tolerance (consult the NSK or SKF datasheet), then secure the bearing to the mounting surface using the specified bolt torque and engage the locking collar or set-screw on the shaft to prevent axial slip. Hand-rotate the shaft through several complete turns with a dial indicator, laser alignment tool, or feeler gauge to confirm smooth operation and proper shaft runout within spec. - How often should I grease a mounted bearing?: Use the formula (OD in mm) × (Width in mm) × 0.005 = grams for periodic relubrication of the bearing element only; initial housing cavity fill is separate and should be 30–50% of free volume. Over-greasing damages seals and generates excess heat—stick to the calculated quantity and recommended relubrication schedule. - What temperature should a mounted bearing run at?: Monitor housing surface temperature (the standard MRO measurement point): 40–65°C is normal, 70–75°C warrants investigation of misalignment or over-greasing, and 80°C requires immediate shutdown. The inner race runs 15–30°C hotter than the housing surface, so an 80°C housing reading means lubricant degradation is accelerating and the bearing requires emergency diagnosis. - When should I replace a mounted bearing?: Replace based on condition: vibration signature analysis or ultrasonic emission (detected with a hand-held meter) indicates wear hours or days before audible noise appears, and is the actionable MRO signal. Other replacement triggers include continuous operation above 80°C housing temperature, visible grease leakage, or reaching the manufacturer's service interval for your duty cycle. Scheduled relubrication and temperature monitoring extend service life significantly — replacement is a last resort, not preventive maintenance. - What are the main types of mounted bearings?: Mounted bearings come in four main forms: pillow blocks (flat-base, shaft parallel to mounting surface), flange mounts (perpendicular shaft, available in 2-bolt and 4-bolt variants with different radial ratings), hanger bearings (overhead support for long horizontal shafts), and take-up frames (adjustable center-distance units for belt or chain drive tensioning). Select based on your shaft orientation, load direction, and space constraints. - How do I choose the right type of bearing for my application?: Start with the load and how it’s applied. You need to know if you’re dealing with radial loads, axial loads, or a mix of both. Then look at speed, operating environment, and space constraints. For example, ball bearings are great for high speed and lighter loads, while roller bearings handle heavier loads but usually at lower speeds. If there’s contamination, moisture, or heat involved, you may need sealed bearings or specific materials. In most cases, the right choice comes down to matching load type, speed, and environment to the bearing design. - How do I choose the right bearing for my application?: Bearing selection depends on five key factors: 1. Load Type and Direction — Determine whether your application has radial loads (perpendicular to shaft), axial loads (along the shaft), or combined loads. Deep groove ball bearings suit primarily radial loads; tapered roller bearings excel at combined loads; thrust bearings handle pure axial forces. 2. Rotational Speed — Ball bearings support higher speeds with lower friction. Roller bearings are better for medium-speed, heavy-load applications. Verify bearing speed ratings against your operating RPM. 3. Load Capacity — Select a bearing with adequate load capacity for your application. Basic dynamic load rating (C) and basic static load rating (C₀) determine how much load the bearing can safely carry. 4. Lubrication Requirements — Choose between grease and oil lubrication based on speed, temperature, and load. High-speed or high-temperature applications typically require oil circulation; lower-speed applications can use grease. 5. Precision and Rigidity — Evaluate your application's tolerance for runout deviation. High-precision applications require tighter tolerances and higher-grade bearings. - What is bearing life (L10) and how does it affect my equipment maintenance?: L10 Life Definition (ISO 281) — L10 is the basic rating life at which 90% of a large group of identical bearings are statistically expected to survive under constant load and speed. It is calculated in millions of revolutions using the formula: L10 = (C/P)^p, where C is the basic dynamic load rating, P is the equivalent dynamic bearing load, and p is the life exponent (3 for ball bearings). Converting L10 to Operating Hours — To express L10 life in hours: L10h = (L10 × 10^6) / (60 × n), where n is rotational speed in RPM. For example, a bearing with L10 = 1,000 million revolutions operating at 3,600 RPM has approximately L10h ≈ 4,630 hours. Modified Life (L10a) — Actual bearing life also depends on lubrication quality, contamination, speed, temperature, and bearing accuracy. ISO 281 defines a modified life factor (a₁ × aISO) that adjusts the theoretical L10 for these real-world conditions. High-quality lubrication and proper maintenance can extend bearing life significantly; poor lubrication or high contamination reduces it. Why It Matters for Maintenance — L10 life helps you schedule preventive maintenance, budget for bearing replacement, and select bearings adequate for your duty cycle. - How should I maintain and lubricate bearings?: Lubrication Importance — Improper lubrication causes over 40% of bearing failures. Proper bearing lubrication prevents friction damage, dissipates heat, protects against corrosion, and acts as a barrier against contaminants (dust, moisture, debris). Lubrication Selection — Choose between grease and oil based on: - Grease: Suitable for low-to-medium speed, sealed bearings, and applications without continuous circulation. Easier to apply and retain. Common for motors, household appliances, and sealed units. - Oil Mist or Circulating Systems: Better for high-speed applications, high-temperature environments, and heavy-load machinery where heat dissipation is critical. Best Practices: 1. Map all lubrication points and create a maintenance schedule. 2. Use the correct lubricant type and viscosity grade specified by the bearing manufacturer. 3. Store lubricants in sealed, labeled containers away from moisture and contaminants. 4. Monitor bearing temperature and vibration; unusual heat or noise may indicate inadequate lubrication or bearing wear. 5. Replace bearings before reaching L10 life if contamination or lubrication failure is detected. - What are dynamic and static load ratings, and why do they matter?: Static Load Rating (C₀) — The maximum load a stationary or slowly rotating bearing can support without permanent deformation of its rolling elements or raceways. Defined by ISO 76 as the load producing 0.01% permanent deformation of the rolling element diameter. Static load capacity is the limiting factor when a bearing operates at very low speeds or remains stationary under heavy loads. Dynamic Load Rating (C) — The constant load a bearing can endure for a specified number of revolutions (the L10 life, at which 90% of identical bearings are expected to survive). Dynamic load rating determines how long a bearing will last under rotating or oscillating motion. ISO 281 defines the L10 calculation using the formula: L10 = (C/P)^p, where C is dynamic load rating, P is equivalent dynamic load, and p is the life exponent (3 for ball bearings, 10/3 for roller bearings). Why They Matter — Static load rating determines if a bearing can handle peak loads without permanent damage (even if not rotating). Dynamic load rating determines operational life. For high-speed applications, dynamic rating is critical. For low-speed or stationary loads, static rating may be the limiting factor. Always verify both ratings against your application's load profile. - What bearing materials are available and which should I use?: Standard bearing materials include: - Chrome Steel — Premium bearing steel used by SKF, NSK, Timken, and most manufacturers. Offers excellent hardness, fatigue resistance, and durability in standard industrial applications. Most common for ball and roller bearings. - Stainless Steel — Provides corrosion resistance for applications in wet, humid, or chemically corrosive environments. Used in food processing, marine, and pharmaceutical equipment. - Ceramic Hybrid Bearings — Combine steel races with ceramic rolling elements. Offer reduced friction, lower heat generation, and higher temperature capability. Used in high-speed, high-precision applications and aerospace. - Polymeric Bearings — Utilize fluoropolymer composites with embedded graphite or PTFE. Provide low friction in high-speed applications where lubrication film breakdown would be problematic. Material selection depends on operating environment (temperature, moisture, chemical exposure), speed, load, and precision requirements. Standard chrome steel bearings suit most industrial MRO applications. - What is a bearing and what does it do?: A bearing is a mechanical component that enables smooth rotational or linear motion by reducing friction between moving parts. Bearings support loads and facilitate the transfer of forces between moving elements, preventing direct metal-to-metal contact that would cause wear and heat buildup. Rolling element bearings contain balls or rollers that rotate within races (raceways) to minimize friction. Common types include ball bearings (used for moderate loads and high speeds), roller bearings (used for heavy loads at medium speeds), and angular contact bearings (designed for combined radial and axial loads). Bearings are essential in industrial equipment including motors, pumps, compressors, gearboxes, turbines, and conveyor systems.
