WPWDKA Universal Speed Cast Iron Worm Reducer — Product Overview
Zero coupling hardware at both ends, in-situ maintenance access, in any of 5 WPW mounting orientations — the maximum-specification A-type universal 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.

WPWDKA Worm Reducer — Core Features
■ Four Features: Universal Body + D-Split + IEC A-Flange + K Hollow Bore
Zero coupling hardware at both ends, in-situ maintenance access, in any of 5 WPW mounting orientations — the maximum-specification A-type universal reducer.
■ IEC A-Type Flange — Direct Motor Mount from Below
A-type IEC flange eliminates the motor adaptor. Motor bolts on in four bolts from below in any WPW orientation.
■ K Hollow Bore — Coupling-Free Shaft at Any Orientation
Driven shaft inserts directly through the K-bore in any WPW orientation — no coupling hardware at the output.
■ D-Split Cover — In-Situ Access in Any Orientation
Cover removes for worm wheel inspection in any WPW mounting orientation with motor and shaft connected.
■ One Product — Complete Motorised Hollow Bore A-Type Drive
Eliminates all direction-specific motorised hollow bore A-type reducer variants — one WPWDKA covers all requirements.
■ Output Torque to 4,440 Nm — Full Capacity
Four features do not reduce torque ratings. Size 250 delivers 4,440 Nm.
