WPWKV Universal Speed Cast Iron Worm Gearbox
Hollow bore extended shaft drives — combining the shaft-mount convenience of hollow bore output with the extended shaft reach of V-type geometry — in a universal housing for multiple installation orientations represent a specific OEM drive configuration for wide belt, multi-drum, and spanning shaft-mount applications. The WPWKV Universal Speed Cast Iron Worm Gearbox combines the WPW universal body, K-type hollow bore with V-type extended geometry, and ratios 1/5–1/60 in a single cast iron housing. Extended hollow shaft drives in any orientation from one standard product.

Universal W-Body Structure
The WPW-series universal housing is manufactured as a single FC20+ grey cast iron casting with bore positions, keyway orientations, and oil channels configured for the selected shaft direction. All 5 shaft direction configurations (A/B/C/D/E) use the same casting geometry with specific machining per configuration.
Hardened 20CrMnTi steel worm shaft with case-hardened tooth flanks (55–60 HRC). The worm shaft and its bearings are selected for the specific input orientation of the model — A-type (below), S-type (overhead), or bilateral — ensuring rated bearing life in the correct load direction.
Tin-bronze ZCuSn10Pb1 alloy worm wheel machined to mesh precisely with the hardened worm shaft. The bronze material provides excellent anti-seizure properties and wear-in characteristics for the worm gear mesh.
Output shaft in quenched-and-tempered steel with double-lip oil seals rated for the specific output orientation (horizontal, vertical upward O-type, vertical downward X-type, side T-type, or extended V-type). Seal selection matches the hydrostatic pressure requirements of the installed orientation.
Single-stage oil bath lubrication. Oil fill port, oil gauge, vent plug, and drain plug are positioned for the selected shaft direction configuration. Fill quantities are specified per configuration in the installation guide — do not use generic fill values across configurations.
FC20+ cast iron foot-mount base integrated with the housing casting. Four mounting holes for B3 foot mounting. The base orientation is fixed for the selected shaft direction configuration. For shaft-mount (hollow bore) applications, the torque arm boss provides housing restraint.
Core Features & Benefits
■ Universal W-Body + K Hollow Bore (V Extended): Extended Shaft-Mount Any Orientation
WPWKV provides K-type hollow bore with V-type extended geometry in all 5 WPW shaft direction configurations. Extended hollow shaft-mount drives in any installation orientation from one standard product.
■ Extended Hollow Bore: Longer Shaft Reach Without Output Coupling
V-type extended hollow bore provides greater shaft engagement length or wider span from the gearbox housing face — without introducing an output coupling on the shaft-mount side.
■ Full WP Torque Through Extended Hollow Bore
WPWKV extended hollow bore rated for full WP torques subject to the overhang load table for the extended shaft geometry.
■ Torque Arm Boss for Extended Hollow Shaft-Mount
WPW universal body torque arm boss compatible with WPWKV extended hollow bore shaft-mount in all 5 shaft direction configurations.
■ H7 Hollow Bore Tolerance — Extended V-Type Geometry
H7 tolerance maintained in the V-type extended hollow bore, ensuring consistent shaft fit quality across the extended bore length.
■ 5 Shaft Direction Configurations Available
All 5 configurations (A–E) available with K hollow V extended output.
