Dry bearing composite bushing is based on high quality and low carbon steel plate, intermediate sintered spherical bronze powder, a mixture of polytetrafluoroethylene (PTFE) and lead on the surface, and rolled bearing (can be made into flanging bearings, shims, gaskets, etc.). The utility model has the advantages of small friction coefficient, good wear resistance, good corrosion resistance and no oil lubrication.
The use of this product can reduce costs, reduce mechanical volume, avoid biting phenomenon and reduce mechanical noise. At present, it has been widely used in the sliding parts of various machines, such as gear pumps, hydraulic components, pneumatic components, printing machines, textile machines, tobacco machines, fitness devices, hydraulic trucks, micro motors, automobiles, motorcycles and agroforestry machines.
It is applicable to work without oil. The static and dynamic friction coefficient is close to prevent the "crawling" phenomenon.
The temperature range is wide, and it can work in the temperature range of -195 C to +270 degree C. Good wear resistance, low friction coefficient and long service life.
It has good corrosion resistance and can be used in various corrosive media (including liquids and gases). The mechanical strength is high, and it can withstand large stable load and dynamic load. It can reduce vibration, reduce noise and improve working environment.
