FAQ

Q: Can a slightly noisy bearing keep running for a short time?
A: Not recommended. Noise means pitting on raceway or balls. Damage spreads rapidly under heavy load and may cause seizure and gear breakage.

Q: Can I press the bearing by hammering outer ring?
A: No. Impact damages raceway and balls. Use special fitting tool or thermal installation.

Q: The bearing looks intact, how to judge internal damage?
A: Check for binding and excessive play during rotation. Rough gritty feeling indicates internal failure.

Q: What risk if mixing new and old bearings on one shaft?
A: Different internal clearance causes uneven load. New bearing bears excessive force and fails prematurely.
