Description
WPWKS Universal Speed Cast Iron Worm Reducer — Product Overview
Universal P-housing with overhead S-type input and coupling-free K hollow bore — overhead motor geometry with direct shaft connection in any of 5 orientations.
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.

WPWKS Worm Reducer — Core Features
■ WPW Universal Body + S Overhead + K Hollow Bore
Universal P-housing with overhead S-type input and coupling-free K hollow bore — overhead motor geometry with direct shaft connection in any of 5 orientations.
■ S-Type Overhead Input — Compact Lateral Footprint
Motor overhead reduces lateral machine width — any WPW mounting orientation.
■ K Hollow Bore — Coupling-Free Output at Any Orientation
Driven shaft inserts directly through K-bore in any WPW mounting orientation.
■ Shaft-Mount + Overhead Motor in Any Orientation
Torque arm boss enables shaft-mount with overhead motor in any WPW orientation — the most compact drive configuration.
■ Output Torque to 4,440 Nm — Full Capacity
Torque ratings identical to WPW.
■ One Product — All Overhead Hollow Bore Drive Positions
Eliminates direction-specific overhead hollow bore reducer variants.
