Detailed Description

Ball-roller combination slewing ring is designed to accommodate axial, radial, and tilting moment loads acting singly or in combination. This kind of slewing ring bearing features long lifespan and large outer diameter and mainly used in applications where eccentricity ratio e(e=2 xMx 1000/Fa x Dpw) is smaller than 1.2.
