Timken JLM714149 Differential Bearing - Rear or Rear Right

Timken differential bearing for heavy-duty axles

The Timken JLM714149 is a tapered roller differential bearing built for heavy-duty driveline service. It is engineered to handle both radial and axial loads while supporting higher speeds, heavier loads, and longer service life.

Compatible with Ford medium- and heavy-duty truck applications, including rear right positions on Rockwell axle setups, this bearing is a direct fit for a wide range of service needs. The JLM714149 part number is also referenced by SKF under the same application.

Key features

• Tapered roller bearing design for differential service
• Manages radial and axial loads in one component
• Compact design with durability-focused engineering
• Suitable for demanding axle and driveline applications
• Timken engineering support and bearing technology

Detailed description

Timken JLM714149 is a differential bearing designed for use in axle assemblies where load control and long service life matter. The bearing dimensions include a 75 mm inside diameter, 25 mm cone width, and 3.00 mm cone radius, which are important for correct bearing selection during differential service. This part number is used across multiple Ford truck applications, including Ford F-600, Ford F-700, Ford F-800, Ford F-Super Duty, CF7000, CF8000, C8000, CF6000, FT800, B-600, B-700, B-7000, F-7000, F-8000, and F-500 models in specified rear axle positions.

For Ford F-600 and Ford F-700 service, as well as Ford F-800 and Ford F-Super Duty applications, the JLM714149 supports Rockwell axle configurations listed in the fitment data. Use the exact axle notes and position details to confirm application before ordering.

What this bearing helps address

• Excessive differential bearing wear
• Noise from a worn axle bearing
• Improper load support in the differential assembly
• Service issues caused by bearing fatigue or damage
• Fitment problems when replacing a worn tapered roller bearing

Installation notes and tips

Confirm the axle model, position, and bearing dimensions before installation. Timken notes that both the inner cone and outer cup should be replaced together to maximize reliability and service life. Match the bearing to the listed Rockwell axle notes for the correct Ford application.
