Technical Excellence
Advanced Metallurgy: We use high-alloy steels such as 20CrMnTi and 17CrNiMo6. Every gear undergoes controlled carburizing and quenching to achieve a surface hardness of HRC 58-62.
Precision Grinding: All gears are finished on high-precision CNC gear grinding machines to reach DIN Grade 5 accuracy, ensuring minimal noise, low vibration, and 98%+ transmission efficiency.
Rigid Housing Design: Gearbox casings are cast from high-strength gray iron or fabricated steel, stress-relieved and machined on CNC boring mills to ensure perfect shaft alignment under maximum load.
Smart Lubrication: Integrated sensors for oil temperature, pressure, and vibration monitoring are available for predictive maintenance . Optimized lubrication circuits and heat dissipation designs to handle the continuous high-temperature cycles of steel production.
Precision Internal Engineering: Our gearboxes are powered by in-house machined High-Strength Industrial Gears and shafts, ensuring minimal backlash and superior load capacity.
Manufacturing Edge
**In-House Precision Machining.** The lifespan of a gearbox depends on the alignment of its housing. We utilize large-scale CNC Gantry Machining Centers to process our gearbox casings in a single clamping. This ensures that the center distance and parallelism of the shaft holes are maintained within microns, preventing uneven gear wear and premature failure.
