Cast Bronze Bearing

HLDB cast bronze bearing with graphite is made of strong cast bronze with special solid lubricants embeded. The base metal withstands high load and the solid lubricants provide self-lubrication. The bearing shows excellent performance without pre-lubrication under conditions of extreme high or low temperature with low speed. This material provides a maintenance-free bearing solution, which can be applied under dry, high temperature, high pressure, corrosive, water or other chemical environments. It is widely used in plastic industries, water engineering, dam gate, mineral machines, ships, hydraulic turbines, etc. Also applied into construction machinery.
