## Product's reviews:
- Great customer service - ITEMS WERE IN STOCK, QUICK DELIVERY AND GREAT CUSTOMER SERVICE.
- P90 coupler - These where a perfect match saved me time and money by getting them fro you guys
- 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.
- Replacement pillow block bearing - I ordered 2 Dodge Pillow block bearings to replace replace a failed bearing on my chipper and to replace a second bearing as a precaution. I received the both bearings promptly, but discovered that the failed bearing also damaged it's housing. Since the housing without a bearing doesn't seem to be readily available, I requested to return the one bearing and replace it with the complete pillow (housing with bearing). Since I was getting an entirely different part, MROSupply customer support suggested that I get a full refund for the bearing and place a new order for the pillow block (housing with bearing). I have received the pillow block and am waiting for the refund which I expect to receive very soon.




## 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.
