Crossed Roller Slewing Bearings With External Gear

External gear slewing bearings are generally composed of four parts: inner ring, outer ring, rolling element, and separator. As the core component adopts slewing bearing, it can carry the axial load and radial load at the same time. Although there are many types of cross roller type slewing bearings, their structures are basically the same. The single-row cross roller type slewing bearing is composed of two rings, and it features a compact structure, lightweight, and high manufacturing precision, it carries an axial load, overturning moment, and large radial load at the same time. The ring gear with internal or external teeth can be selected according to different applications. it also features easy installation and usage. The cross-roller type slewing bearings are widely used in lifting, transportation, and construction machinery.
