Sliding Bearing Manufacturing Materials

1) Metal materials such as bearing alloys, bronze, aluminum-based alloys, zinc-based alloys, etc.

Bearing alloy: bearing alloy also known as white alloy, mainly tin, lead, palladium or other metal alloy, because of its wear-resistant type, high plasticity, good running performance, good heat conductivity and good resistance to glue and good adsorption with oil, so it is suitable for heavy load, high-speed situation, bearing alloy strength is small, more expensive, when used must be cast in bronze, steel belt or cast iron shaft tile, form a thin coating.

2) Porous metal materials (powder metallurgical materials)

Porous metal material: porous metal is a powder material, it has porous tissue, if it is immersed in lubricants, so that the micro-porous filled with lubricant, into oilbearing bearings, with self-lubricating properties. The toughness of porous metal material is small and can only be adapted to smooth impact-free loads and medium and small speed slower.

3) Non-metallic materials

Bearing plastic: commonly used bearing plastics are phenolic plastic, nylon, Teflon, plastic bearings have a greater pressure strength and wear resistance, can be used oil and water lubrication, but also self-lubricating performance, but poor thermal conductivity.

Sliding bearings in the work due to the contact between the shaft neck and shaft tile will produce friction, resulting in surface heating, wear and even "bite to death", so in the design of bearings, should be used to reduce the mo-like good sliding bearing material to manufacture shaft tiles, suitable lubricants and the use of appropriate supply methods, improve the bearing structure to obtain thick film lubrication.
