Metallic self-lubricating bearings

Metal self-lubricating bearings provide initial lubrication to reduce the initial lubricating film of friction, use solid lubricants, arranged in the direction of bearing movement, form a lubricating film, improve friction coefficient and wear resistance, use bronze alloy, provide mechanical strength, improve impact resistance and corrosion resistance.
