Metal-based solid inlaid oil-free bearings

A high-performance solid lubricating product with graphite and MoS2 composite solid lubricant embedded on the metal matrix. It breaks through the limitations of general bearings that rely on oil film lubrication. During use, the solid lubricant is rubbed against the shaft by frictional heat to form an excellent lubrication condition for oil and powder to coexist, which not only preserves the shaft from wear, but also makes the solid lubrication properties eternal.

Its hardness is twice as high as that of ordinary copper sleeves, and its wear resistance is also twice as high. At present, it has been widely used in metallurgical continuous casting machines, train supports, steel rolling equipment, mining machinery, ships, gas turbines and other high temperature, high load, low speed and heavy load applications.

Multi-layer composite oil-free bearing

With steel plate as the base body, 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.

The use of this product can reduce the cost, reduce the mechanical volume, avoid the phenomenon of shaft biting and reduce the mechanical noise. Products have been widely used in the sliding parts of various machinery, such as printing presses, elevators, textile machines, tobacco machines, exercise machines, hydraulic pallets, micro motors, solenoid valves, automobiles, motorcycles and household machinery.


Linear bearings, non-standard parts, PTFE soft belts, FB bronze bearings, JF bimetal bearings, SF-1 oil-free bearings, SF-2 boundary lubrication bearings, FZ steel ball cage series, powder metallurgy oil bearings, graphite inlays Self-lubricating bushings, TF graphite scattered embedded gold bearings, alloy inlaid high wear-resistant bearing bushes.
