MANUFACTURING PROCESS

6-STAGE PRODUCTION PROTOCOL

ZGBK adheres to a rigorous industrial workflow, ensuring every bearing meets global precision standards from raw material to final shipment.

01
Heat Treatment

Advanced controlled atmosphere furnaces ensure optimal hardness and metallurgical stability of bearing steel.

02
Precision Grinding

Automated grinding lines achieve micron-level dimensional accuracy on raceways and ring surfaces.

03
Super-finishing

Honing and super-finishing processes reduce surface roughness for smoother rotation and lower noise.

04
Component Cleaning

All rings, balls, and cages are thoroughly cleaned to eliminate contamination before assembly.

05
Precision Assembly

Automated assembly with strict radial clearance control ensures consistent internal geometry.

06
Final Quality Testing

Every bearing undergoes vibration, noise, clearance, and dimensional inspection before packaging.
