FAQ

Q: Can this cylindrical roller bearing take heavy axial thrust?
A: It is designed mainly for radial load with limited axial capacity. Thrust bearing or thrust plate is required for large axial force.

Q: Can the bearing with intermittent noise keep running temporarily?
A: Not recommended. Noise means pitting on rollers or raceway. Damage spreads rapidly under heavy load and may seize and break gears.

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

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