Multi-stage continuous helical gear meshing
Larger tooth contact area reduces vibration and noise, covering high-speed ratio 3.77 to low-speed high-torque ratio 281.71.
Full stepped power range from 0.12kW to 250kW
The product line ranges from light-duty 0.12kW small conveyors to heavy 250kW mixing, mining and lifting machinery. It adapts to light assembly lines and heavy industrial high-load conditions without missing power specifications.
Modular universal housing with optional solid/hollow output shaft
The unified frame can switch reduction ratios simply by replacing internal gear components, with two output options: solid shaft and hollow shaft. Hollow bore supports flat key and shrink disc locking, and horizontal, vertical, side-mounted installation are all available.
High transmission efficiency & energy saving for long continuous operation
Helical gears cut friction loss greatly, delivering stable overall efficiency of 92%~96%, far superior to worm reduction gearboxes. It effectively reduces electricity expenditure for 250kW heavy machines running round the clock.
High rigidity & heavy load capacity with strong shock resistance and long service life
Uniform stress distribution enhances tooth root bending strength, allowing the gearbox to withstand frequent start-stop, instant overload and forward-reverse shocks. Thick cast iron housing resists deformation, slowing wear of gears and bearings under dusty, high-temperature and humid harsh environments.
Simplified selection within one series to cut inventory cost
One single series covers full ratio range 3.77~281.71 and power range 0.12~250kW. Customers do not need to stock multiple reducer types; matching motors and mounting brackets share high compatibility to reduce stock SKUs.

Q:How to confirm if a reducer matches the motor power?
A: Refer to the rated power marked on the reducer nameplate. The motor power shall not exceed the maximum matching limit of the housing. Select a lower power model for heavy-duty working conditions to prevent overheating from long-term overload.
Q: What basic notes should be followed during reducer installation?
A:Ensure coaxiality of input and output shafts and fasten the mounting base firmly. Fill lubricating oil to the middle scale for horizontal units, and follow factory oil level standards for vertical types.
Q:What causes abnormal noise during reducer operation?
A:Common reasons include insufficient lubricant, worn gears/bearings, loose installation or shaft misalignment. Check the oil level first; disassemble and inspect internal transmission parts if noise persists.
