#50AB-SL4
Water Lubricated Aluminum Bronze Bearing
The #50AB-SL4 water lubricated aluminum bronze bearing adopts copper alloy with HB>150 as its base material. The oil-free bearing is inlaid with water lubricant, and its working surface has drilled holes.
The bearing with water lubricant is extremely resistant to heat and corrosion. A fragile phenomenon never occurs at low temperature. The water lubricated aluminum bronze bearing can be used at extremely low temperature. It is especially applicable to seawater and river environments such as the ships, valves, water turbines, water treatment, and the environmental engineering, etc.
