1. The roller body adopts 40MN2 round steel forging technology with good comprehensive performance, and the tempering + quenching process ensures the wear resistance of the product;

2. After finishing grinding, the surface of the shaft will be polished to reduce the temperature rise inside the roller body and the wear mass loss of the bushing, thus improving the service life of the products;

3. Local hardening treatment of the thrust surface of the cover can better bear continuous heavy load and lateral extrusion capacity, further improving the adaptability of mine operation conditions.
