The slewing bearing is composed of three parts: the inner ring, the outer ring, and the rolling element. It can simultaneously carry a large axial force, radial force and a certain tilting moment. It is a general-purpose large-scale with comprehensive performance bearing. The inner and outer rolling rings have high-strength bolts respectively fixed on the turntable or chassis frame.
Longwei transmission slewing bearing Product type:
1.Single Row Four Point Contact Ball Slewing Bearings.
2.Single Row Crossed Roller Slewing Bearings
3Double Row Ball Slewing Bearings
4.Three Row Roller Slewing Bearings
5.Thin Section Slewing bearings(Light type).
6.Thin Section Slewing Bearings (Flange type)
– these preloaded slewing rings can support higher loads than four point contact bearings. They have proved themselves particularly where bearings are subjected to high radial forces and moderate axial and tilting moment loads
– they are suitable for applications with uniform running free from stick-slip, low rotational resistance and high requirements for axial and radial runout accuracy and rigidity, for example in robots, handling systems and machine tools.
