Double Row Different Diameter Ball Slewing Bearing

The double-row reducing ball slewing bearing has three races, and the steel balls and spacers can be directly discharged into the upper and lower races. According to the stress conditions, two rows of steel balls with different diameters are arranged. Can bear axial force and radial force at the same time.
