A one-way bearing is a bearing that can be turned freely in one direction and locked in the other direction. One-way bearings are also called overrunning clutches, just named according to different industries and different functions. The metal shell of a one-way bearing contains many rollers, needles or balls, and the shape of its rolling seat (hole) makes it roll only in one direction, and it will produce a lot of resistance in the other direction (the so-called "one-way").

The tight-fitting sleeve is the most common component for bearings with tapered holes to be positioned on cylindrical shafts, as it can be used for optical shafts or stepped shafts.

The bushing is an annular thin-wall bearing component, usually made of wear-resistant material, used to support and guide the movement of the shaft to reduce friction and wear on the shaft. Bushings can be divided into two types: sliding bushings and rolling bushings, where sliding bushings use the relative movement of their surfaces to reduce friction and wear, while rolling bushings support and guide the movement of the shaft by applying pressure between the rolling surfaces.

A cross roller bearing is a special type of rolling bearing characterized in that the cylindrical rollers are arranged vertically with each other on a 90-degree V-grooved rolling surface by a spacer. This structure enables the cross roller bearing to withstand loads from all directions at the same time, including radial loads, axial loads and torque loads. Because the roller is in linear contact with the track surface, the possibility of elastic deformation of the bearing under load is small.

The design concept and manufacturing technology of automobile hub bearing unit are successfully applied to the field of heavy truck bearing. The conventional two sets of single-row tapered bearing series are designed as an integrated bearing unit. The compact structure design of the product not only has the weight advantage of the bearing weight, but also helps the lightweight design of related parts; The product has an independent lubrication system; The bearing and wheel hub assembly into one, easy to run, assembly and disassembly; The product has the advantages of light weight, low friction, energy saving and consumption reduction.
