Helical-Bevel Geared Reducer
KC Helical-Spiral Bevel Geared Reducer
Right-Angle Output via Spiral Bevel Gear Stage · Heavy-Duty Industrial Reducer
The KC helical-spiral bevel geared reducer combines a hardened helical input stage with a spiral bevel gear output stage, delivering smooth, quiet right-angle power transmission for demanding industrial drives. Its heavier frame construction (up to size 167/187 in combination) and motor power range of 0.12–200kW make it suited to continuous heavy-duty operation. Supplied with solid or hollow output shaft (with shrink-disk clamping option), in foot or flange mounted configurations, with a KC..RC combination available for extra-low output speeds.

Frequently Asked Questions
Common questions about the KC helical-spiral bevel geared reducer
How is KC different from RC?+
RC is a pure helical gearbox with a right-angle output via a helical gear pair. KC uses a spiral bevel gear stage for its right-angle output, which is generally chosen for heavier, larger-frame industrial applications requiring very smooth, quiet running under continuous heavy load. Tell us your torque and speed requirement and we'll recommend the right series.
What frame sizes and power range does KC cover?+
Standard KC frames go up to size 167, and the KC..RC combination (adding a helical pre-stage) extends coverage to frame combinations like 187/107 for higher ratios. Motor power spans 0.12kW to 200kW, covering light industrial through heavy continuous-duty drives.
What output shaft options are available?+
KC is available with a solid output shaft, a hollow shaft, or a hollow shaft with shrink-disk clamping for direct, coupling-free mounting onto your driven equipment shaft.
Is OEM/custom specification available?+
Yes. We support custom shaft configuration, mounting position, terminal box orientation and branding with flexible MOQ. Contact us via WhatsApp for OEM pricing and exact dimensional drawings for your frame size.
