Smooth Operator: Quiet & Dependable Ball Bearing

As a result of using this product, I found that my machinery runs so much more smoothly! The ball bearing is extremely quiet and functions with great reliability... I appreciated that it came with a specified load capacity to help me determine if it was a good fit for my needs. IT arrived in good condition and was easy to install. Unfortunately, the packaging wasn't very protective, so there was a chance that the product could have been damaged during transportation..

Pros
  • Smooth, quiet, specified load capacity
Cons
  • Poor packaging

Loose and lumpy for bearings

This new bearing has more play than the 70 year old bearing I replaced. Defects on the balls can be felt when turning the inner ring. The product is of very poor quality. Bearing unmarked, box says China. I would like it better.

Pros
  • Nice to use
Cons
  • Disappears
