High Speed Large Diameter Slewing Ring Bearing without Gear for Ladle Turret

Xuzhou Wanda Slewing Bearing Co.,Ltd. is a slewing bearing manufacturer specializing in standard and non-standard slewing bearing.Over the years, we supplied high quality product & good service to every user and gain good credit.We have strict quality control system in our own factory,meanwhile, we have passed ISO9001-2008 Quality System Certification and JG/T66-1999, JG/T67-1999, JG/T68-1999, JB/T2300-1999 with our country’s engineering & machinery standards.

The Single Row Four Point Contact Ball Slewing Bearing is composed of 2 seat rings.It features compact in design,and light in weight.The balls contact with the circular race at four points,via which the axial force,radial force and resultant moment may be born simultaneously.
It may be used for slewing conveyer, welding arms and positioners,light,medium duty cranes,excavators and other engineering machines.

The single row four point contact ball slewing rings is composed of two seat rings, which design in compact structure and light weight, steel ball contact with the circular raceway at four points; it can bear the axial force, radial force and the tilting moment at the same time.

It can be used for slewing conveyer, welding manipulator, light & medium duty crane, excavator, and other construction machinery.

A slewing bearing or slew[ing] ring is a rotationalrolling-element bearing or plain bearing that typically supports a heavy but slow-turning or slow-oscillating load, often a horizontal platform such as a conventional crane, a swing yarder, or the wind-facing platform of a horizontal-axis windmill. (To "slew" means to turn without change of place.)

Compared to other rolling-element bearings, slewing bearings are thin in section and are often made in diameters of a metre or more; the slewing bearings on the Falkirk Wheel are 4 metres diameter and fit over a 3.5 metre axle. Slewing bearings resemble oversize aircraft control surface bearings.

Slewing bearings often use two rows of rolling elements. They often use three race elements, such as an inner ring and two outer ring "halves" that clamp together axially.

Slewing bearings are often made with gear teeth integral with the inner or outer race, used to drive the platform relative to the base.
