 Technical Parameter Table

Working Principle 

• R Series: Multi-stage helical gears mesh coaxially for in-line speed reduction and torque increase.

• F Series: Parallel-shaft helical gears transmit power in parallel layout.

• K Series: Front helical drive + rear spiral bevel gears for 90° direction change.

• S Series: Front helical stage improves efficiency; rear worm gear realizes high ratio and self-locking.Speed and torque are changed via tooth ratio, converting high-speed low-torque motor power to low-speed high-torque output.

Main Applications

• R Series: Assembly lines, fans, pumps, mixing equipment

• F Series: Textile, printing, packaging, automation lines

• K Series: Cranes, mining machinery, mixers, heavy conveyors

• S Series: Lifting platforms, roller shutters, small conveyors, light automation

• Widely used in metallurgy, chemical, grain, building materials, logistics, etc.

Production Process

• Raw Material Inspection → 2. Forging / Precision Forging

• Pre-heat Treatment (Normalizing) → 4. CNC Turning

• Hobbing / Milling / Gear Shaping → 6. Carburizing & Quenching or Tempering

• Low-temperature Tempering → 8. Bore & End Face Grinding

• Gear Grinding / Shaving → 10. Deburring, Cleaning, Flaw Detection

• Accuracy & Meshing Test → 12. Anti-rust & Packaging

Cautions

• Overload and over-speed operation are strictly prohibited to avoid tooth breakage

• Dry running without oil is forbidden to prevent scuffing and wear

• Do not strike tooth surfaces during installation to avoid precision damage

• Keep housing sealed to prevent dust and moisture ingress

• For S series, avoid long-term heavy load to prevent overheating and efficiency drop

• Stop immediately for inspection if abnormal noise, vibration or overheating occurs

• Replace gears in pairs when severely worn

• Store in dry and ventilated environment to prevent corrosion
