Four-point contact ball slewing bearing

Double-row ball slewing bearing

Three-row cylindrical roller slewing bearing

Cross roller bearing

Raceways

The raceways of slewing rings are quenched on the surface. Its quenching hardness is HRC55-62, making sure that its effective hardening depth is enough.

Production Process

Raw material

LYJW bearing rings are made of high quality 42CrMo/50Mn and the raceway surface is quenched. We can provide rings of other materials according to customer’s specific requirements.

Rough turning

* After rough turning, the workpiece is detected by an ultrasonic flaw detector to examine cracks or other flaws and ensure the bearing’s stable quality and normal service life.

Heat treatment

* Perform medium frequency hardening on the surface of bearing raceway to form a hardened layer with hardness≥55HRC, depth≥4mm and the width of soft zone is≤50mm with a “S” mark on it.

Gear Processing

For bearings with external or internal gear, gear processing should be performed prior to grinding process to achieve the required
gear accuracy.

Drilling

Program on the CNC drilling machine according to the drawing and verify the size accuracy prior to drilling holes.

Grinding

Fine grinding: 46 or 60 grit resin grinding wheel is used to finely process the slewing bearings and achieve the required surface finish and size accuracy.

Assembly

After grinding, pre-assembly is carried out to calculate and adjust the clearance.After adjusting the clearance, check the start friction torque. If it is not acceptable, adjusting the race way and clearance again to achieve the required value.

Inspection- Calipers

LYJW performs strict quality control in compliance with ISO9001-2015 Quality Management System. Every process from materials to finished products is inspected and documented to control the quality of every piece of bearing.
