description

Taper roller bearing is a core load-bearing component of drivetrain system. With tapered roller structure, it can bear radial force and axial thrust simultaneously, reduce friction of rotating pairs, stabilize clearance and ensure smooth operation of transmission and final drive. Roller spalling, raceway wear, excessive clearance and poor lubrication will cause abnormal noise, overheating and transmission jitter, and may even lead to jamming and damage of transmission parts.

FAQ 

Q：Can I replace the cone or cup separately?
A：Separate replacement is not recommended. The cone, cup and rollers are matched and ground as a set, mixed assembly will cause abnormal clearance and rapid wear.

Q：What are common causes of overheating?
A：Too small preload clearance, insufficient or wrong lubricant oil and excessive axial thrust load are the main reasons.

Q：How much preload should be applied during installation?
A：Preload value varies for different machines, follow official Cat service manual instead of empirical operation.

Q：Can I keep running if the bearing has sanding noise?
A：Stop operation immediately. Noise indicates damaged raceway or rollers, continuous operation will destroy the whole drivetrain assembly.
