WPWKA Worm Reducer — Core Features

■ WPW Universal Body + A-Type Input + K Hollow Bore

Universal P-housing with A-type input from below and K hollow bore coupling-free output — shaft-mount in any of 5 WPW orientations.

■ K Hollow Bore — Coupling-Free in Any Orientation

Driven shaft inserts directly in any WPW mounting orientation — no coupling hardware regardless of installation position.

■ A-Type Below Input — Standard Motor Coupling

Standard A-type bilateral input shaft accepts conventional motor coupling hardware from either side.

■ Universal Shaft-Mount — 5 Orientations

Torque arm boss enables shaft-mounting the WPWKA in any WPW orientation — foot-mount and shaft-mount both available.

■ Output Torque to 4,440 Nm — K-Bore Full Capacity

WPWKA torque ratings identical to WPWK at all sizes.

■ One Product — All A-Type Hollow Bore Orientations

Eliminates direction-specific A-type hollow bore reducer variants from the BOM.

Frequently Asked Questions — WPWKA Universal Speed Worm Reducer

▶ How does WPWKA differ from WPKA?
WPKA uses a fixed WP housing A-type only. WPWKA uses the universal P-housing supporting 5 orientations. Same torque ratings and hollow bore dimensions.
▶ What are the hollow bore diameters for WPWKA?
Same approximate diameters as WPWK. Contact Ever Power with your specific size and shaft diameter requirements.
▶ Can WPWKA be shaft-mounted in any WPW orientation?
Yes. Torque arm boss supports shaft-mount in any WPW orientation.
▶ What is the maximum output torque for WPWKA?
Size 250 delivers up to 4,440 Nm — identical to WPWK.
▶ Does WPWKA support foot-mount and shaft-mount?
Yes. Both base plate and torque arm boss are present.
