Drivetrain Maintenance

Gearboxes, reducers, drive shafts and backstop arrangements use bearings that manage combined radial and axial loads. Incorrect preload, contact angle or mounting orientation can quickly cause heat, noise and gear wear. Maintenance teams care about replacing the complete arrangement to the original specification and keeping shaft positions correctly documented.

• Check the mounting arrangement and set the correct axial clearance or preload when replacing tapered roller bearings.
• Match angular contact bearings for contact angle, arrangement and load direction instead of relying on bore and outside diameter alone.
• Identify each bearing by shaft position so that input, intermediate and output shaft parts are not mixed.
• For backstops and indexing drives, confirm the required rotation direction and torque when specifying one-way clutch bearings.
