Timken LM503310 Tapered Roller Bearing Cup

Product Description

The TIMKEN LM503310 is a tapered roller bearing cup, also known as the outer race, designed to work in conjunction with a matching tapered roller bearing cone to manage both radial and axial loads. This cup is precision-engineered to seat the tapered rollers of the cone assembly, distributing load forces efficiently across the bearing contact surface. Built to TIMKEN specifications, it delivers durability in compact bearing housings and is suited for front axle and differential applications. Licensed mechanics and drivetrain technicians are the primary installers of this component.

This bearing cup is used in front axle and differential assemblies across a range of passenger car applications. Application data from the supplier indicates fitment for Jaguar cars from 1988 through 2006, Mercedes-Benz cars from 1972 through 1991, Porsche from 1977 through 1989, and Audi cars for the 1991 model year, all in front axle and differential positions. This part is sold individually as a single unit and is intended to be paired with the corresponding cone at the time of replacement.

Key Features

• Tapered outer race geometry supports combined radial and axial load capacity
• Engineered for higher operating speeds and extended service life
• Designed to be replaced as a matched set with the companion bearing cone
• Compact profile fits within standard front axle and differential bearing bores
• Manufactured by TIMKEN, a recognized global producer of tapered roller bearings

Compatibility

Fits front axle and differential bearing positions on Jaguar cars (1988-2006), Mercedes-Benz cars (1972-1991), Porsche (1977-1989), and Audi cars (1991), as specified in application data. Always verify the bearing bore diameter and cup outside diameter against vehicle service specifications before installation.

Installation Notes

Installation should be performed by a qualified automotive or drivetrain technician. Before removing the old bearing cup, relieve any load on the axle assembly and consult the vehicle service manual for disassembly procedures. The cup should be pressed squarely into the housing bore using an appropriate bearing driver or press; never drive it in at an angle. Replace the cone and cup together as a matched set to ensure proper load distribution and bearing life.
