We focus and control every production detail,Only for the delivery of good products to customers.
Product available including: Single and Double Row Ball, Three Row Roller, Cross Roller Sealed and Unsealed Internal Geared, External Geared and Non-Geared Clearance or Preloaded.
Turntables and Slewing Rings are offered in both metric and inch sizes with the ability to customize the mounting interfaces to suite your application. What differentiates Slewing Rings from Turntables is the inclusion of gear teeth on either the inner or outer rings.
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.

FAQ :
1 LW Slewing Bearing Heat Treatment
Heat Gear Slewing Bearings are in the majority of cases supplied with spur tooth. Stub teeth also is ok.There are two kinds of tooth hardening. They are normalizing and tempering, According to the different applications, there are two ways of quenching. They’re whole tooth quenching and single-tooth quenching. Single-tooth quenching can be divided into tooth surface & root quenching and tooth surface quenching.
2 . The Calculation of Slewing Bearing.
Static load capacity
The determined loads must be multiplied with a factor fstat allocated to the application. The product Fa’ or Mk’ must be below the static critical load curve of the selected bearing.
With regard to radial loads in load combinations
Fa = axial load
Fr = radial load
Mr = tilting moment
3 Protection Against Corrosion
We make Protection Against Corrosion on surface of bearing,and make couple of packing paper.
4.Customize.
Yes,we have professional technical terms.
5.Warranty:
General 1 year.
- Reliable reputation.
