WPWDK Universal Speed Cast Iron Worm Reducer — Product Overview
Universal P-housing with direct IEC motor mounting, K hollow bore coupling-free output, and D-split in-situ maintenance cover — zero coupling hardware at either end in any WPW shaft direction.
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.

WPWDK Worm Reducer — Core Features
■ Four Features: Universal Body + IEC + K-Bore + D-Split
Universal P-housing with direct IEC motor mounting, K hollow bore coupling-free output, and D-split in-situ maintenance cover — zero coupling hardware at either end in any WPW shaft direction.
■ IEC Flange — No Adaptor at Any Shaft Direction
IEC 72-1 flange at the input stage eliminates the motor adaptor across all 5 WPW shaft direction configurations.
■ K Hollow Bore — Coupling-Free Shaft Insertion at Any Orientation
K-type through-bore accepts the driven shaft directly at any WPW output shaft direction — no coupling, no coupling maintenance, no coupling fatigue in any orientation.
■ D-Split Cover — In-Situ Access in Any Configuration
Cover removes for worm wheel inspection in any WPW shaft direction — universal maintenance access across all installation orientations.
■ Single Product — All Motorised Hollow Bore Drive Positions
WPWDK eliminates the need for direction-specific motorised hollow bore reducer variants — one product model covers all installation orientations.
■ Output Torque 2.2–4,440 Nm — Full Capacity Retained
Four features do not affect worm gear torque ratings. WPWDK size 250 delivers 4,440 Nm — the same as WPW.
