Characteristic of smooth roller：

1. The roller is made of cast steel material, and the working face and shaft shoulder of the roller are welded with special wear-resistant welding materials, which are hard and wear-resistant. The internal strength of the roller is high in bending and breaking resistance, which improves the wear-resistant ability and overcomes the defects of cracking, water leakage, block dropping and roller breaking after welding of the general roller, and prolonging the service life.

2. The surface of the roller can not be precision machined by the external circular grinder except between the shafts, which can be finished by the lathe. Other parts: the working surface of the roller, the bearing position and the connecting end of the wheel are precision machined by the external circular grinder to ensure the coaxiality of the roller, improve the product quality and prolong the service life.
