Faulty Bearings, Avoid at All Costs

based on our own experience these bearings are nothing but trouble. We purchased a batch for our industrial and scientific equipment, and have had to replace nearly a third of them due to defects within the first few days of use. While they are reasonably priced, the time and effort required to constantly replace faulty parts is not worth any potential savings. .

Pros
  • Reasonably priced
Cons
  • Frequent defects and malfunctions.

Silent Saviors: Groove Bearings Triumph

As my tests showed, these bearings were incredibly silent and smooth... They fit perfectly and helped me reduce friction, leading to better overall performance. The only downside was that they were a bit difficult to install, but once they were in, they proved their worth..

Pros
  • Smooth and noiseless operation
Cons
  • Some users have reported difficulty with installation

Don't buy them for a bike wheel.

Cheap cheap cheap. I have no idea why they even make them when they are the worst bearings money can buy. I only bought them to add to the landfill. Don't buy this. The wheel had so much play that the rim rubbed the brake pads so hard that one of them broke off, falling off and damaging my carbon wheel.

Pros
  • 688-2Z Bearing protected on BOTH SIDES to keep grease inside
Cons
  • No performance
