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.
