Product details

A bearing shell is the contact component between a plain bearing and the journal. It features a smooth, tile‑shaped semi‑cylindrical surface, and is normally manufactured from wear‑resistant materials such as bronze and anti‑friction alloys. Under special conditions, it may also be made of wood, engineering plastics or rubber.

Bearing shells fall into two types: solid and split. The solid‑type bearing shell is commonly referred to as a bushing. Solid bushings are available with or without oil grooves. Bearing shells are clearance‑fitted with journals and generally do not rotate with the shaft.

During the operation of a plain bearing, a thin oil film is required between the bearing shell and the rotating shaft for lubrication. Poor lubrication will result in direct friction between the bearing shell and the rotating shaft, generating extremely high temperatures. Even though bearing shells are made of special high‑temperature‑resistant alloy materials, the excessive heat from direct friction can still burn them out.

High‑Load Self‑Lubricating Bearing ShellLiner: Fabric wound from wear‑resistant fibers and special high‑strength fibers serves as the sliding layer. Outer liner: Polymer‑fiber‑reinforced high‑temperature high‑strength epoxy resin acts as the load‑bearing layer. It delivers high dynamic load‑bearing capacity, excellent impact resistance, superior anti‑friction properties, moderate corrosion resistance and a low friction coefficient. It supports oil‑free or minimal‑oil lubrication, requiring little or no maintenance in service and offering a long service life.
