WPWDK Universal Speed Cast Iron Worm Gearbox
The combination of direct IEC motor connection and hollow bore shaft-mount output — zero couplings on both sides — in a gearbox that also supports all installation orientations is the most flexible motorised shaft-mount drive specification available. The WPWDK Universal Speed Cast Iron Worm Gearbox delivers exactly this: WPW-series universal body (5 shaft direction configurations), D-type IEC motor flange (direct motor, no input coupling), and K-type hollow bore output (direct shaft mount, no output coupling). For OEM machine builders and plant engineers who need a motorised shaft-mount drive that works in any orientation, the WPWDK is the definitive single-product solution.

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
■ D-IEC Flange + K Hollow Bore + Universal Body: Zero Couplings, All Orientations
WPWDK integrates three features: D-IEC motor flange (no input coupling), K hollow bore output (no output coupling), and WPW universal body (5 shaft directions). The complete zero-coupling motorised shaft-mount drive in any orientation.
■ D-Split Housing: In-Situ Service with Motor and Shaft Connected
D-split housing cover removes without disturbing the IEC motor or the hollow bore driven shaft — in all 5 shaft direction configurations. Universal in-situ serviceability for the zero-coupling drive system.
■ IEC Motor Frame Range: M8 to M16
Full range from M8 fractional (0.06 kW, size 40) to M16 heavy industrial (14+ kW, size 250). All IEC motor sizes for standard industrial conveyor and process drives are covered.
