WPWK Worm Reducer — Core Features
■ WPW Universal Body + K Hollow Bore — Universal Shaft-Mount
P-housing shaft direction flexibility with coupling-free hollow bore output. Shaft-mount in any of 5 installation orientations without an output coupling — the universal shaft-mount reducer.
■ K-Type Hollow Bore — Driven Shaft Direct Insertion
H7-tolerance through-bore with GB/T 1095 keyway accepts the driven shaft directly in any WPW shaft direction. No coupling hardware regardless of installation orientation.
■ Shaft-Mount Capable — Torque Arm Boss Standard
The torque arm boss enables shaft-mounting the WPWK directly onto the driven shaft in any WPW shaft direction configuration — foot-mount and shaft-mount both available.
■ Output Torque to 4,440 Nm — K-Bore Does Not Reduce Capacity
WPWK worm gear internals are identical to WPW. Hollow bore output does not affect torque ratings across all 11 sizes.
■ Bore Diameters 12–90 mm — All Standard Shaft Sizes
Hollow bore diameters from 12 mm (size 40) to 90 mm (size 250) cover the full range of standard industrial shaft diameters in a single universal product series.
■ Universal Housing — One Product for Multiple Shaft Directions
WPWK covers all WPW shaft direction requirements with hollow bore output — eliminating the need for direction-specific hollow bore reducer variants.
WPWK Worm Reducer — Industry Applications

☷ Universal Shaft-Mount Conveyor Drives
WPWK shaft-mount on conveyor head shafts in any orientation — horizontal, inclined, or vertical — using one product model, eliminating direction-specific hollow bore SKUs.
⚊ Agricultural Equipment Shaft Drives
Agricultural machinery with shaft-mount drives in multiple positions (auger heads, spreader shafts, irrigation) uses WPWK universal body to standardise the hollow bore drive on one product.
⚒ Multi-Orientation Industrial Shaft Drives
Industrial equipment with hollow bore shaft drives in multiple orientations standardises on WPWK — one product model, all installation geometries, coupling-free output.
⚙ Universal Agitator Shaft Drives
Process vessel agitator shafts in various installation positions use WPWK universal hollow bore — one product covers horizontal, vertical-up, vertical-down, and side output agitator configurations.
