Exact dimensions

Measured the 6202 bearings with calipers and they are within standard tolerance. Very happy with the precision for this price point.

Perfect for motor repair

I used the 6203 ZZ bearings to repair my bench grinder motor. They fit perfectly and the motor runs much quieter now. Great value for the price.

Very quiet operation

Installed these in a ventilation fan. The noise level dropped significantly compared to the old worn-out bearings. Smooth rotation right out of the box.

Great bulk price

Bought a pack for future maintenance projects. Keeping them in sealed packaging until needed. Seems like a reliable brand for general machinery.

Good quality, slow shipping

The bearings themselves are excellent quality and match the specifications. Only giving 4 stars because shipping took a bit longer than expected.
