Zx200 Excavator Turntable Slewing Ring Bearing China Best Quality

A single row four-point contact slewing bearing usually makes a second bearing unnecessary, which provides some very important benefits:

• space savings

• weight savings

• cost savings

• rigidity and accuracy

• faster installation

• less maintenance

• integral mounting holes, gears, etc.

Thanks to a unique ball path geometry that produces twice as many contact points, a four-point contact slewing bearing can resist radial, thrust and moment loads individually or in any combination. It has one row of balls with an inner race and an outer race. The ball grooves are generated from two centers, with each radius slightly larger than the ball radius. Contact angles are typically 35° off the radial centerline, but can be varied to suit the application.
