## Customer Reviews

### ⭐⭐⭐⭐⭐ good bearing, replacement for tensioner pulley bearing
*by A***R on April 15, 2025*

I used this to replace a chirping tensioner pulley bearing on our Honda, and seems like a good quality bearing. It's nice and quiet and spins perfectly true and smooth. Time will tell how it holds up. I needed a press to get the old bearing out, but it saved me about 2/3 the cost of a replacement pulley from the local auto parts house.

### ⭐⭐⭐⭐⭐ Still one of the best bearing makers
*by K***0 on January 19, 2025*

Fit perfectly, smooth and quiet. If you know how to replace bearings correctly you can save a lot of money on your vehicles rather than buying an entire pulley, pump, etc.

### ⭐⭐⭐⭐⭐ Good quality
*by E***J on February 12, 2025*

Good bearing. Genuine NSK
