SK450 Excavator Slewing Rng Bearing 

When the rotary support bearing is working, the inner and outer rings realize relative rotation through the combination of rolling elements. When the external force acts on the bearing, the load is transmitted to the inner and outer rings, and is transmitted to each other through the rolling element, achieving the carrying capacity. At the same time, the rolling motion of the rolling element reduces the friction force and improves the rotation efficiency of the bearing. Therefore, the rotary support bearing can achieve smooth rotating motion in various equipment and withstand various loads in different directions.
