WPWEK Double Speed Cast Iron Worm Reducer — Product Overview
The WPWEK extends the WPWE universal body concept to hollow bore output — adding the K-type coupling-free shaft insertion capability to the universal shaft direction platform at extreme ratios. Applications requiring shaft-mount installation in any of the WPW shaft direction configurations at ratios above 1/60 use WPWEK as the single universal hollow bore extreme-ratio drive.

WPWEK Double Speed Worm Reducer — Core Features
■ WPW Universal Body + K Hollow Bore + Double Stage — Universal Shaft-Mount Extreme Ratio
The WPWEK provides the universal shaft direction flexibility of the WPW body combined with K-type hollow bore output and dual-stage extreme ratio reduction. Any WPW shaft input direction, coupling-free shaft insertion at the output, ratios from 1/200 to 1/900+.
■ K Hollow Bore — Direct Shaft Connection at 6,050 Nm Maximum
The driven shaft inserts directly into the K-type hollow bore even at maximum output torques of 6,050 Nm (size 155–250). No output coupling at any torque or ratio level.
■ Universal WPW Body — Multiple Shaft Directions
WPW shaft direction flexibility extends to the K-bore output configuration — universal shaft-mount capability in all WPW input direction configurations.
■ Shaft-Mount Capable — Torque Arm Available
The torque arm boss enables shaft-mounting the WPWEK directly on the driven equipment shaft. Universal WPW body configurations remain available in shaft-mount mode.
■ Dual Independent Oil Chambers — Both Stages
Two independently sealed chambers for both gear stages. Oil volumes specified per WPW shaft direction in the lubrication table.
■ FC20+ Dual-Chamber Universal Housing — Rigid Shaft Alignment
Single-cast FC20+ grey cast iron dual-chamber universal housing maintains inter-stage and output bore alignment across all WPW shaft direction configurations.
WPWEK Worm Reducer — Industry Applications
☀ Universal Solar Tracker Shaft-Mount Drives
WPWEK universal body accommodates multiple tracker shaft direction configurations in a single product model — K-bore shaft-mount at extreme ratios, any WPW input direction for the specific tracker geometry.
⚙ Multi-Orientation Shaft-Mount Conveyor Drives
Conveyor systems with head shafts in multiple orientations use WPWEK universal body hollow bore drive — one product model, all shaft directions, extreme ratios, direct shaft insertion.
