WPWS Universal Speed Cast Iron Worm Reducer — Product Overview
Universal P-housing with S-type (above) input shaft — overhead motor geometry in the universal body’s multi-orientation mounting platform.
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.

WPWS Worm Reducer — Core Features
■ WPW Universal Body + S-Type Overhead Input
Universal P-housing with S-type (above) input shaft — overhead motor geometry in the universal body’s multi-orientation mounting platform.
■ S-Type Above Input — Reduced Lateral Footprint
Motor mounts vertically above the housing. Reduces lateral machine width versus A-type side-mounted motor configurations in constrained installations.
■ 11 Sizes: 40–250 mm — Full Industrial Range
Same torque range as WPW: 2.2 Nm (size 40 / 1/5) to 4,440 Nm (size 250 / 1/60).
■ Universal P-Housing — 5 Mounting Orientations
S-type input combined with universal P-housing enables overhead motor geometry in any of the 5 standard WPW mounting orientations.
■ Bilateral S-Type Input — Either Side
S-type input shaft bilateral — motor couples from either side of the overhead input shaft.
■ N150–N220 Lubrication — S-Type Adjusted Volumes
Oil volume specified for S-type overhead input orientation. Use the WPWS lubrication table for correct fill volumes.
WPWS Worm Reducer — Industry Applications
⚒ Narrow-Frame OEM Machine Overhead Drives
OEM builders with lateral width constraints use WPWS overhead motor geometry — universal body covers all mounting orientations within the narrow frame requirement.
⚊ Compact Conveyor Overhead Motor Drives
Conveyor drives in constrained-width channels use WPWS overhead S-type input to keep motor within the frame width.
⚙ Pump Station Compact Drives
Pump stations with multiple drives in constrained lateral spacing use WPWS overhead motor — universal body for varied mounting orientations.
☷ Agricultural Narrow Machine Drives
Agricultural row-crop machinery with narrow working widths uses WPWS overhead motor to keep drive hardware within row spacing limits.
