WPWK Universal Speed Cast Iron Worm Reducer — WPW Series

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.

The WPW P-housing accommodates all five standard shaft direction configurations in a single casting — eliminating the need for direction-specific housing variants. Input power from 0.06 kW (size 40) to 98 kW (size 250), output torques from 2.2 Nm to 4,440 Nm across 11 standard sizes.

■ 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.

☷ 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.

■ ISO 9001:2000 Certified Production

Every WPW unit is manufactured under ISO 9001:2000 quality management. Raw material inspection, in-process checks, and final testing are documented and traceable.

■ CE Marking — EU Machinery Directive 2006/42/EC

Full CE compliance for export to EU, UK, Australian, and New Zealand markets.

■ Pre-Shipment Testing: Noise, Leak, Torque

Noise below 68 dB(A) at rated load, 30-minute pressurisation leak test, and output torque within ±5% of rated. Non-conforming units reworked before shipment.

■ FC20+ Material Certification

Housing castings verified by mill certificates: minimum 220 MPa tensile strength, 160–200 HB hardness.

“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.”
