Precision movement starts with precision manufacturing. JOC produces bearing housings, rings, cages, and gear blanks to tight tolerances, supported by balanced heat treatment and controlled surface integrity. As a China manufacturer and trusted supplier, we unify forging, turning, grinding, and shot-peening to secure load capacity, low noise, and long service life.

Material cleanliness and process control. We use certified alloy steels with defined inclusion levels, manage case depth on carburized gears, and keep roundness, runout, and tooth profile within spec. For bearings, we guard raceway roughness and residual stress to prevent premature spalling; for gears, we optimize tooth micro-geometry to minimize transmission error.
Traceability and repeatability. From raw bars to final inspection, we document every step under ISO/TS systems, enabling stable mass production and reliable aftermarket supply. Need AGMA/DIN grade targets or NVH constraints? We’ve got you. **Let’s align specs—**contact our engineers through Contact Us today.
