010.20.280 four point contact ball slewing bearing

Single-row four point contact ball slewing bearings consist of outer ring and inner ring which can support axial, radial and tilting moment loads at the same time.

  • We often provide other two types bearings as follows:
    – Single-row four point contact ball slewing bearing (internal gears)
    – Single-row four point contact ball slewing bearing (external gears)
  • Here you will find details of such kind of bearings.

Main technical specifications of CNC vertical grinding machines : Working diameter 300mm-1700mm.
Equipment and Production capacity: We possess high precision mechanical equipments, such as CNC
vertical lathes, CNC vertical grinding machines, CNC gear shaping machines, and magnetic powder
detecting machines for roller and rings. The inside diameter of CHG bearings range from 100mm
from 4500mm, either standard and nonstandard, and the accuracy of bearings can reach P4. CHG have
high-precision roller production line and heat treatment equipment, which make a solid foundation
for manufacturing high-precision products.

vertical lathes, CNC vertical grinding machines, CNC gear shaping machines,and magnetic powder
detecting machines for roller and rings. The inside diameter of CHG bearings range from 100mm from
4500mm, either standard and nonstandard, and the accuracy of bearings can reach P4. CHG have high-
precision roller production line and heat treatment equipment, which make a solid foundation for
manufacturing high-precision products.

CNC gear shaping machines

Main technical specifications of CNC gear shaping machines:
1.Maximum working outside diameter: external tooth / interanl tooth 1600 / 2100mm;
2.Maximum modulus 16mm;
3.Maximum tooth width 330mm.
Equipment and Production capacity : We possess high precision mechanical equipments, such as CNC vertical
lathes, CNC vertical grinding machines, CNC gear shaping machines, and magnetic powder detecting machines
for roller and rings. The inside diameter of CHG bearings range from 100mm from 4500, either standard and
nonstandard, and the accuracy of bearings can reach P4. CHG have high-precision roller production line and
heat treatment equipment, which make a solid foundation for manufacturing high-precision products.

Heat Treatment Equipment 

We possess heat treatment equipments. In order to make sure the surface hardness and stability after heat-
treatment, heat-treatment carburizing is controlled by computer, which will exactly control the carbon potential
concentration and the depth of carburized layer. This can make a solid foundation for manufacturing high-precision
products.
