Item NO.: CHB-600
CHB-600 bronze bushing. Based on high strength brass, lubricating by oil added in the groove, which has the same performance with Tin bronze bushing but with much higher hardness, the life time for low speed application is 2 times of tin bronze bushing. It can be used in heavy load condition.
We can offer different materials and make the bushings and oil grooves according to customer’s drawings and requirements.
