Summary:

The Manufacturing Material Of The Bearing

1) Metal materials, such as bearing alloys, bronze, aluminum-based alloys, zinc-based alloys, etc.
Bearing alloy: Bearing alloy, also known as white alloy, is mainly alloy of tin, lead, antimony or other metals. Because of its good wear resistance, high plasticity, good running-in performance, good thermal conductivity and good resistance to glue and oil It has good adsorption, so it is suitable for heavy load and high speed. The strength of the bearing alloy is small and the price is more expensive. When used, it must be cast on bronze, steel belt or cast iron bearing bushes to form a thinner coating.
2) Porous metal materials (powder metallurgy materials)
Porous metal material: Porous metal is a kind of powder material. It has a porous structure. If it is immersed in lubricating oil, the micropores are filled with lubricating oil, and it becomes an oil-containing bearing with self-lubricating properties. Porous metal materials have low toughness and are only suitable for steady non-impact loads and medium and low speeds.
3) Non-metallic materials
Bearing plastics: Commonly used bearing plastics include phenolic plastics, nylon, polytetrafluoroethylene, etc. Plastic bearings have greater compressive strength and wear resistance, and can be lubricated with oil and water. They also have self-lubricating properties, but have poor thermal conductivity.
