TCB80 Casting Bronze Bearing
Structure Characteristics and Applications
TCB800 is based on the copper alloy. It offers technically and economically favorable bearings solutions. It is of high load capability, low weight and good corrosion resistance. TCB800 can offer different types of bronze alloys according to the required life time, service etc. The tolerance is much tighter than wrapped bronze bushes. This kind of products are widely used in machine-tool, agricultural machinery, crane electromotor, spring pin, steering shaft and transmission, etc. We can use different copper alloy material as per customer's requirements.
