This bushing is engineered to provide support and reduce friction in specific areas of the truck’s engine or transmission system, ensuring smooth operation and longevity of the vehicle.

Basic Concepts of Bushings

Bushings are mechanical components used to provide a bearing surface between two parts. They are typically made from materials that can withstand wear and reduce friction, such as bronze, nylon, or various types of rubber ¹. Bushings differ from other types of bearings, like ball bearings or roller bearings, in that they do not have rolling elements. Instead, they rely on their material properties to facilitate motion and absorb vibrations. This makes them particularly useful in applications where low-speed, high-load conditions are common ².
