Product Details

Rear Outer Differential Pinion Bearing (HM88649) by Timken®. Get optimum vehicle performance with Timken bearings. Timken manufactures ball bearings, cylindrical roller bearings, and tapered roller bearings, and all feature premium design, enhanced surface finishes, and are manufactured using quality materials to ensure longer bearing life and excellent antifriction properties.

Bearings are components that make a vehicle's motion possible, allowing moving parts to rotate with minimal friction and taking a load. Without bearings, the vehicle's parts would quickly wear out from friction. Typically, bearings in a vehicle have to deal with radial and thrust loading. Radial load makes the bearing rotate or roll as a result of tension. Thrust load, or axial load, is associated with the bearing's carrying capacity and is applied parallel to the bearing's axis. When it comes to the vehicle, its weight carries a radial load, however, when it goes around a turn, the bearings deal with a thrust load from the cornering forces.

As a global leader in manufacturing bearings of all types, Timken makes every effort to ensure each and every bearing will stand up to extreme situations, successfully handle loading, and feature improved uptime. Using its wealth of experience designing and manufacturing bearings, well-equipped production facilities, and expert craftsmanship, Timken produces bearings that are synonymous with reliability. The quality of materials Timken selects combined with sophisticated design result in top-grade bearings that help your vehicle run efficiently for a long time. Timken is the only bearing manufacturer in the world that makes its own steel, so the quality of bearings is backed by using only clean, high-alloy steel. Timken also implements its Worldwide Quality Standards in every manufacturing facility to make sure each bearing meets the same performance standards wherever in the world it's made.
