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.
Ever Power Manufacturing Quality — WPWK Worm Reducer

■ FC20+ 材料认证
铸件经工厂证书验证:抗拉强度最低为 220 MPa,硬度为 160–200 HB。
WPWK Universal Worm Reducer — Customer Reviews
“WPWK universal hollow bore on our conveyor system. Multiple shaft directions covered by one product model. K-bore on each shaft, torque arm in position. No coupling hardware anywhere in the system.”
“Used WPWK on our agricultural equipment shaft drives. Universal body covers all shaft positions on the machine. K-bore eliminates the coupling hardware exposed to field conditions.”
“WPWK on our multi-orientation agitator shaft drives. One product covers vertical-up, horizontal, and side output agitator positions. Coupling-free connection at all positions.”
“Good universal hollow bore reducer. WPWK-90 on multiple shaft positions. All working well. Would appreciate a full bore diameter table for all sizes published in the product documentation.”
