Two-metal sliding bearing material is the company's new products, from multi-metal composite material bearings, introduced steel liner back as the matrix material bearing layer, so that bearing with a high structural strength, anti-friction self-lubricating layer Materials from copper-based alloys bearing, it does not hurt dual, and can tolerate high-and low-temperature working conditions. When the pairs for the relative movement, friction in the solid lubricant on the surface, forming a layer of film to prevent inter-metal contact, thus reducing the coefficient of friction, increased the load bearing capacity.It is not easy to apply to the formation of the film re-load, high temperature, low temperature, vacuum, water vapor and inconvenience to add lubricants, dust, shock, and other conditions under the conditions of use. Well-structured, high-capacity, a good dry run and anti-fatigue properties.
