Thanks. - Perfect fit and finish - Good product, perfect fit and finish, good price and fast shipping. Thanks - Shaft - Worked well to repair Dodge Gear Box ## 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. - What are the typical load-carrying capacities for 2-bolt flange bearings?: Load capacities vary by bore size—smaller units (15-20mm bore) typically handle 12,800-20,000N dynamic loads, while larger units (70-90mm bore) can exceed 96,000N. Always consult the specific bearing model datasheet for exact dynamic and static load ratings to ensure proper application selection. - What maintenance is required for 2-bolt flange bearings?: 2-bolt flange bearings are prelubricated with grease and equipped with a grease fitting (zerk) for periodic relubrication. Typical maintenance involves regreasing every 500-1,000 operating hours depending on speed and load conditions, and inspecting seals for wear or damage during routine equipment maintenance. - What are 2-bolt flange bearings and what applications are they used for?: 2-bolt flange bearings (UCFL series) are mounted ball bearing units with cast iron housings designed for industrial applications including conveyor systems, fan/blower units, and light machinery. The two-bolt mounting pattern provides easy installation in space-constrained areas while supporting radial and moderate axial loads. - What is the difference between set screw and eccentric collar locking?: Set screw locking uses two set screws tightened directly onto the shaft to prevent rotation, providing reliable holding in constant-direction applications. Eccentric collar locking uses an off-center collar that clamps the bearing to the shaft when tightened, offering similar security with potentially easier adjustment. - What bore sizes are available for 2-bolt flange bearings?: 2-bolt flange bearings are manufactured in standard bore sizes from 15mm to 90mm, covering metric and inch shaft diameters. Common sizes include 15mm, 20mm, 25mm, 30mm, 40mm, 50mm, and 70mm to match industrial equipment requirements. - What is the main advantage of a flanged mounted bearing over a standard bearing?: Flanged mounted bearings have an integrated mounting flange that acts as a built-in retaining surface, eliminating the need for separate brackets, adapters, or machining. The flange provides precise axial positioning and simplifies installation by allowing you to bolt directly to your housing surface, reducing assembly time and cost. - What mounting surface requirements must I meet for proper flange installation?: The mounting surface must be flat and stable to prevent angular, axial, or parallel misalignment that can cause edge loads and premature bearing failure. Confirm that your housing face is clean and flat within tolerance, and that all bolt holes align correctly before installation. - Do flanged mounted bearings require periodic maintenance like standard bearings?: Many flanged mounted bearings come with permanent grease lubrication sealed for life, eliminating the need for re-greasing during operation. However, some designs may require periodic relubrication depending on operating conditions, so always verify the maintenance requirements with your bearing's technical documentation. - What critical dimensions do I need to know to select the right flanged mounted bearing?: You need to verify four key dimensions: bore diameter (the shaft size), outer diameter (housing bore fit), bearing width, and flange outer diameter and thickness. These specifications ensure proper load distribution and prevent slipping or misalignment during operation. - Can flanged mounted bearings handle both radial and axial loads?: Most flanged mounted bearings are designed to absorb high radial loads, while some units can handle moderate axial loads in both directions. Check the manufacturer datasheet for your specific bearing model to confirm dynamic and static load ratings before final selection. - 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.
