## Product's reviews:
- Recent purchase - My order with MRO was easy, quick and priced just right!
Assistance over the phone was professional and helpful.
I will be making more orders in the future. JG
- 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.
- Great! - Cheapest price I've found on the web.
- P90 coupler - These where a perfect match saved me time and money by getting them fro you guys




## FAQ:

- 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.
