Factory Overview
We operate a full-chain self-production and self-marketing model, covering every step from steel pipe production to finished products. Our partnership factory is equipped with a complete bearing production line with full-process quality control.
Advanced production equipment and strict quality management systems are the foundation of our product quality, with an annual output of 150 million sets.
Main Production Equipment
From raw material to finished product — precision at every step
CNC Grinding Machines
High-precision CNC internal and external grinders achieving micron-level accuracy for raceway roundness and surface finish.
Super-Finishing Machines
Super-finishing of raceway surfaces reduces roughness, improving rotation precision, service life, and reducing noise.
Heat Treatment
Controlled-atmosphere furnaces precisely control quenching and tempering, ensuring optimal hardness, toughness, and wear resistance.
Cleaning Equipment
Multi-station ultrasonic cleaning lines thoroughly remove processing residues, ensuring internal cleanliness for assembly.
Automated Assembly
Semi/fully automated assembly lines precisely control clearance and grease filling, ensuring consistency and reliability.
Packaging Equipment
Automatic oiling and packaging with anti-rust treatment and vacuum packaging for transport and storage protection.
