WPWDA Universal Speed Cast Iron Worm Reducer — Product Overview
Universal P-housing with A-type IEC motor flange and D-split maintenance cover — the motorised in-situ-accessible version of the WPWA in the universal body.
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.

WPWDA Worm Reducer — Core Features
■ WPW Universal Body + IEC A-Type + D-Split
Universal P-housing with A-type IEC motor flange and D-split maintenance cover — the motorised in-situ-accessible version of the WPWA in the universal body.
■ IEC Motor Flange A-Type — Motor Bolts On from Below
A-type IEC 72-1 flange accepts standard motor frames from below without adaptor plate — universal body, direct motor, in-situ access.
■ D-Split Housing — In-Situ Maintenance
Cover removes for worm wheel inspection with motor and driven shaft connected, in any WPW mounting orientation.
■ Universal P-Housing — All Mounting Orientations
WPWDA P-housing supports 5 mounting orientations — one product covers all installation geometry requirements with direct IEC motor.
■ Output Torque to 4,440 Nm — Full Capacity
IEC flange and D-split do not reduce worm gear torque ratings.
■ Single Model Replaces Multiple Direction-Specific SKUs
WPWDA eliminates direction-specific motorised reducer SKUs for A-type input applications — one product, all orientations.
WPWDA Worm Reducer — Industry Applications

⚒ Universal Motorised A-Type Drive Platform
OEM builders use WPWDA as the universal motorised A-type drive — IEC direct, D-split access, all mounting orientations from one product.
