CHB-JNA Bronze alloy metallic bearings with graphite plugs provides both the good wear resistance and great self-lubricating feature of the bearings.
This designation enables the bearings to be operated without oiling or greasing maintenance.
It is widely used in the field of high load and intermittent movement as well as oscillating movement conditions such as automobile assembling line, Water Turbine, Gate dams and Plastic Injection Machinery.
Depending on different working conditions, variety of types of different alloys are available.
