Timken SET118 Tapered Roller Bearing Cone and Cup

Product Description

The TIMKEN SET118 is a tapered roller bearing cone and cup assembly designed to handle both radial and axial loads in demanding mechanical applications. The set includes both the inner cone and outer cup as a matched pair, engineered to maximize service life and reliability when installed together. Tapered roller bearing geometry allows the SET118 to manage heavy loads at higher operating speeds while maintaining a compact footprint. This type of bearing assembly is typically installed by qualified mechanics or drive-train technicians working on commercial and medium-duty vehicle axle and drivetrain systems.

The SET118 is suited for medium-duty drivetrain and axle applications including rear-wheel-drive configurations. Per the supplier application summary, this assembly is noted for use in MD (2003-09), MD (1992-97), and MD (2005-10) configurations under the RW-RWD CHE classification. The matched cone-and-cup design ensures optimal load distribution and reduces the risk of premature wear caused by mismatched bearing components.

Key Features

• Matched cone and cup assembly supplied as a single set for consistent, reliable fitment
• Engineered to carry combined radial and axial loads simultaneously
• Compact tapered roller geometry delivers high load capacity in minimal space
• Both inner and outer races replaced together to maximize bearing service life
• Manufactured to TIMKEN tapered roller bearing standards for dimensional consistency

Compatibility

Per supplier application data, this assembly is designed for RW-RWD CHE medium-duty applications including MD (2003-09), MD (1992-97), and MD (2005-10) configurations. Verify fitment against the specific axle or drivetrain assembly before installation.

Installation Notes

Tapered roller bearing assemblies of this type are installed by qualified drivetrain or heavy-equipment mechanics. Always de-energize, safely support, and lock out the vehicle or equipment before servicing bearing positions. Use a proper bearing press or driver set to seat the cup and cone without damaging the races or rolling elements. Always replace the cone and cup together as a matched set and inspect the bearing seat and journal surfaces for wear before installation.
