Multi-stage parallel helical layout
Multiple sets of helical gears arranged in parallel with standard center distance for compact overall size.
Combined flange & hollow bore end
Integral output end with outer mounting flange and inner through hollow bore for two installation options.
Side oil level sight glass
Built-in oil indicator on housing to check lubricant volume without opening casing.
Flexible space matching
Users pick flange or hollow shaft mounting without modifying machine frame when installation space is limited.
Easy oil management
Visible sight glass helps detect oil shortage or leakage promptly to prevent dry abrasion.
Low running noise
Gradual meshing of helical gears cuts vibration, ideal for indoor and low-noise production lines.

Q:Do different ratios of same power share identical housing dimension?
A: Outer casing size stays same, only internal gear parts differ.
Q: Is extra protection needed for outdoor rainy installation?
A: Standard seal works for occasional rain; extra rain cover is needed for permanent outdoor service.
Q: Is specific tightening order required for flange bolts?
A: Tighten bolts diagonally in several steps to prevent flange deformation and subsequent oil leak.
