Timken 15101 Tapered Roller Bearing Cone

Product Description

The TIMKEN 15101 is a tapered roller bearing cone designed to carry both radial and axial loads in demanding drivetrain and axle applications. As the inner race assembly of a tapered roller bearing set, the cone works in tandem with a matched cup (outer race) to transfer load through the tapered rollers. TIMKEN engineers these components to deliver high load capacity in a compact envelope, making them a standard choice for licensed mechanics and drivetrain specialists working on light- and medium-duty truck axle service.

The 15101 is applied primarily in front-wheel and rear-wheel drive axle assemblies on domestic trucks and utility vehicles. Documented fitment includes DOD TK 1/2 ton trucks from 1984 to 1993, DOD TK 3/4 ton trucks from 1964 to 1999, DOD TK 1 ton trucks from 1958 to 1999, and DOD MD vehicles from 1958 to 1981. It is also noted for FSUV applications. This cone is sold as a single unit and is intended to be replaced together with its mating cup for optimal bearing life and reliability.

Key Features

• Tapered roller geometry supports simultaneous radial and axial load management
• Engineered for higher operating speeds and heavier loads compared to standard radial bearings
• Inner cone assembly designed to be replaced as a matched set with the corresponding cup
• Compact dimensions allow fitment in tight axle and hub assemblies
• TIMKEN manufacture to established global tapered roller bearing standards

Compatibility

Documented fitment includes DOD TK 1/2 ton (1984-1993), DOD TK 3/4 ton (1964-1999), DOD TK 1 ton (1958-1999), DOD MD (1958-1981), and FSUV applications as stated by the manufacturer application summary.

Installation Notes

Tapered roller bearing cone replacement is typically performed by licensed automotive or heavy-equipment mechanics during axle, hub, or wheel-end service. Before service, relieve vehicle load, secure the vehicle on approved stands, and remove any applied bearing preload. Always replace the cone and its mating cup together to avoid accelerated wear. Follow applicable torque and preload procedures per the vehicle service manual, and repack or replace bearing grease as required by the service interval.
