Good quality, slow shipping
Bearing itself is genuine C&U quality. Packaging was secure. Took a bit longer to arrive than expected.

Perfect fit for my motor
Replaced the old noisy bearing with this one. Runs smooth and quiet. Dimensions matched perfectly.

Great value
Much cheaper than local suppliers but same quality. The 2RZ seals keep dust out effectively.

Solid bearing
Works as intended. Grease seems adequate from factory. Would buy again for maintenance jobs.

A: Yes, please contact our sales team for orders over 50 units.
Q: Is the seal resistant to water?
A: The rubber seals offer splash resistance but are not fully waterproof for submersion.

A: Yes, 2RZ and 2RS are generally interchangeable for most applications.
