Timken JM205149 Tapered Roller Bearing Cone

Product Description

The TIMKEN JM205149 is a tapered roller bearing cone designed to handle combined radial and axial loads in demanding drivetrain and wheel-end applications. As the inner race component of a tapered roller bearing assembly, it works in conjunction with a matched cup (outer race) to support shaft rotation under heavy loads. TIMKEN manufactures this cone to close tolerances, providing durable performance in a compact envelope measuring approximately 3.46 inches in diameter and 1.49 inches in height. Licensed HVAC, automotive, and industrial service technicians working on wheel bearings, differentials, and transmission assemblies regularly specify this part for OEM-grade replacement work.

The JM205149 cone is suited for front-wheel and rear-wheel drive applications, including medium-duty and heavy-duty chassis systems. Application data indicates fitment in FW-RWD CHE MD configurations from 1997 to 1998. This bearing cone is appropriate for repair facilities, fleet maintenance operations, and specialty drivetrain shops handling axle and wheel-end service on light commercial and medium-duty vehicles.

Key Features

• Tapered roller design supports simultaneous radial and axial load management
• Engineered for higher rotational speeds and heavier load ratings compared to standard ball bearings
• Compact geometry: 3.46 inches outer diameter, 1.49 inches width
• Cone and cup should be replaced as a matched set to maximize service life and reliability
• Manufactured to TIMKEN dimensional and metallurgical standards for OEM-level durability

Compatibility

Fits FW-RWD CHE MD applications from 1997 to 1998 as stated in supplier application data. Always verify fitment against the specific vehicle or equipment service manual before installation. The matched cup (outer race) should be replaced at the same time as this cone.

Installation Notes

Bearing cone replacement should be performed by a qualified technician familiar with drivetrain and wheel-end service procedures. Before beginning work, secure and support the vehicle or equipment and relieve any load on the bearing assembly. Press-fit bearing cones require appropriate bearing drivers or a hydraulic press; never drive a bearing cone into place with impact on the rolling elements or cage. Follow applicable torque and preload specifications from the OEM service manual for the specific application.
