Timken LM102910 Tapered Roller Bearing Cup

Product Description

The TIMKEN LM102910 is a tapered roller bearing cup, also known as the outer race, designed to seat the mating cone assembly and support combined radial and axial loads. It is engineered for durability in compact bearing envelopes where both load directions must be managed simultaneously. Timken manufactures this cup to close tolerances, ensuring proper fit and load distribution when paired with the correct cone. Typical installers include drivetrain technicians and heavy-equipment mechanics working on wheel-end, differential, and transmission bearing positions.

This bearing cup is identified in application data as a front-wheel and rear-wheel-drive fitment for medium-duty vehicles from 1988 through 2017. It is used in wheel bearing assemblies, axle shaft bearing positions, and similar rotating assemblies where a tapered roller design is specified. When servicing a bearing position, both the cup and cone should be replaced together to maintain matched geometry, load capacity, and service life.

Key Features

• Outer race (cup) component of a tapered roller bearing assembly
• Engineered to handle simultaneous radial and axial loads
• Close-tolerance manufacture for consistent fit and load distribution
• Designed for replacement alongside the mating cone for maximum service life
• Compact profile suitable for space-constrained bearing bores

Compatibility

Application data indicates fitment for front-wheel-drive and rear-wheel-drive medium-duty vehicles from 1988 through 2017. Verify bearing bore diameter, cup outside diameter, and width against the application specification before installation.

Installation Notes

Bearing cup installation is typically performed by a drivetrain or axle technician. The housing bore and surrounding components must be clean and free of debris before pressing the cup into position. Use a proper bearing driver or press to seat the cup squarely; never drive a bearing cup with a hammer directly against the race face. Always replace the cone and cup as a matched set and follow the equipment manufacturer's torque and preload specifications for the bearing position.
