What is the characteristics of slide bush bearing?

The earliest sliding and rolling element bearings were made of wood. Ceramics, sapphires or glass are also used. Steel, copper, other metals, plastics (such as nylon, bakelite, Teflon and UHMWPE) are commonly used.
From heavy-duty wheel axles and machine tool spindles to precision timepiece components, rotary bearings are required for many applications. The simplest rotary bearing is the slide bush bearing, which is just a bushing sandwiched between the wheel and the axle.

This design was subsequently replaced by a rolling bearing that replaced the original slide bush bearing with a number of cylindrical rollers, each of which resembled a single wheel. The first practical rolling bearing with cage was invented by watchmaker John Harrison in 1760 for the production of the H3 chronograph.

A slide bush bearing, comprising: a cylindrical main body portion through which both ends are hollow; an oil flow groove formed in the inner peripheral surface of the main body portion and configured to facilitate oil flow; A boundary portion where the oil flow groove and the peripheral surface of the main body portion are in contact with each other forms a circular circular portion in order to prevent sharp edges from being formed at the mutual boundary.

Slide bush bearing In the field of valve applications, the slide bush bearing is inside the bonnet, and generally uses a corrosion-resistant material such as Teflon or graphite for sealing.

The bushing made of anti-friction material in the sliding bearing is also called slide bush bearing and bushing. Usually cast on the inner surface of the bearing shell, mainly to reduce costs and save valuable abrasive materials. Thickness 0.5-6mm for large or important bearings. The slide bush bearing is mainly used to replace the wear of the shaft, and also has the function of supporting the shaft to run, reduce the friction and wear, and reduce the vibration.
Low-load steel-based copper bush bearing, high-load can use bimetallic slide bush bearing.
