Oilless bearing

What are oilless bearings, and how do they work?

Oilless bearing is a kind of self-lubricating bearing that combines metal and lubrication characteristics. The metal matrix bears the load, and the solid material of special formula (like graphite) acts as lubrication.


The oilless bearing has the characteristics of high carrying capacity, impact resistance, high-temperature resistance, and strong self-lubricating ability.

The sliding bearing of special specifications is suitable for heavy load, low speed, reciprocating or swinging and other occasions that are difficult to lubricate and form an oil film, and are not afraid of water wash and other acids.

Erosion and erosion of liquid. For example, some key equipment of industrial and mining enterprises in the mining environment operates under extremely harsh working conditions. Because the equipment is heavy, the environment temperature is high, the dust is large or the air contains acidic corrosive gases CO, SO2, etc., it brings many problems to the lubrication of the equipment, and the friction and wear are serious.

You can choose the oilless bearing, which has the characteristics of small friction coefficient, wear-resistant and corrosion-resistant, oil-free self-lubricating, and long service life. Using it can reduce costs, reduce noise, and prevent stick-slip.


Metal-based solid inlaid oilless bearing

  • A high-performance solid lubricating product with graphite and other composite solid lubricants embedded on the metal matrix. It breaks through the limitations of general bearings that rely on oil film lubrication.

Multi-layer composite oil-free bearing

  • With a steel plate as the base, the spherical bronze powder is sintered in the middle, and the surface is rolled with a mixture of polytetrafluoroethylene (PTFE) and lead, it is a rolling bearing. It has the characteristics of low friction coefficient, good wear resistance, good corrosion resistance, and no oil lubrication.
