Combined helical & worm drive
Two-stage transmission with front helical gear plus rear worm wheel, input and output shafts run in parallel.
Integral hollow shaft output
Through hollow bore allows customer's drive shaft to insert inside and fasten via key or locking assembly.
Seamless sealed die-cast housing
Alloy one-piece casing with fully enclosed structure to keep internal grease and block dust or oil leakage.
Reliable self-locking function
Inherent worm self-lock prevents load reverse rotation after shutdown, ideal for lifting and conveyor equipment.
Flexible installation
Hollow bore directly fits machine shaft without extra couplings or adapter flanges to cut accessory cost.
Low noise operation
Smooth meshing of helical and worm gears reduces vibration for quiet running performance.

Eight reasons to choose us
Q:Can hollow bore size be custom machined to match client's shaft dimension?
A: Standard bore is default size, customized boring is available with confirmed customer drawing before production.
Q: Will self-lock fail under sudden heavy reverse impact load?
A:Self-lock works under normal load; extra brake is recommended if frequent huge reverse shock exists.
Q: Is original factory oil suitable for extreme high or low ambient temperature?
A: Standard grease fits normal temperature; special temperature-resistant lubricant can be arranged per order notice.
