What is Bearing?

The use of bearings has been very simple since ancient times, dating back to ancient Egypt, even before the invention of the wheel. Nowadays bearing applications can be seen everywhere, and any two surfaces with relative motion will use bearings, from household appliances to industrial machinery. As an Auto Parts Wheel Bearing Factory, let's explain it to everyone.

A bearing is a friction member that is subjected to a load when it comes into contact with another part and moves relative to each other. The relative movement can be by sliding or rotating. There are basically two different types of bearings: composite bearings and rolling bearings. Other types of bearings also include fluid bearings that carry a load of a thin layer of gas or liquid; magnetic bearings that support the load by magnetic force; hinged flexible bearings that support the load with curved elements; and gemstone bearings used in timepieces.

Composite bearings, also known as bushings, bushings or sleeve bearings, are generally cylindrical and do not contain moving parts.

Standard configurations include cylindrical bearings for radial loads, flanged bearings for radial and light axial loads, gaskets and turn-over gaskets for heavy-duty axial loads, and sliding plates of various shapes. Custom designs are also available, including special shapes, features (oil grooves, holes, notches, tabs, etc.) and dimensions.

Composite bearings are used for sliding, rotating, oscillating or reciprocating motion. Sliding applications are commonly used as plain bearings, bearing pads and wear plates. The sliding surface is generally flat, but it can also be cylindrical and always move linearly, not rotationally. Rotating applications involve cylindrical faces and one or two directions of travel. Swing and reciprocating applications involve planar or cylindrical faces that travel in both directions. Such as Wheel Bearing.

The composite bearing structure can be solid or a separate butt joint (rolled bearing) for easy installation. Matching bearings to applications is critical. High loads require bearings to increase contact area and have higher load carrying capacity. Solid lubricant bearings are designed to operate at higher temperatures than lubricating oil and grease lubricated bearings. High-temperature applications require special lubrication measures to minimize heat build-up and friction.

Composite bearings are manufactured in different configurations. The choice of product depends on the operating conditions and performance requirements.
