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.
