WPWX Universal Speed Cast Iron Worm Gearbox
Inverted and sub-floor drives requiring vertical downward output across multiple installation orientations — where the same gearbox model must serve equipment with output shafts pointing down in various machine configurations — combine X-type downward output with universal housing versatility. The WPWX Universal Speed Cast Iron Worm Gearbox provides the WPW-series universal body with X-type vertical downward output across 5 shaft direction configurations. Inverted and sub-floor drives from ratio 1/5 to 1/60 in any installation orientation from a single 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 + X Vertical Downward Output: Downward Drive in Any Orientation
WPWX provides X-type vertical downward output in all 5 WPW shaft direction configurations. Sub-floor and inverted drives in any installation orientation from one standard product.
■ X-Type Output Oil Seals — Downward-Pressure Double-Lip
Vertical downward output shaft seals are double-lip premium seals rated for the hydrostatic pressure from the oil bath above resting on the seal face — same specification as single-orientation WPX.
■ Dual Oil Chambers Calibrated for X-Type Downward Orientation
Oil fill levels are specified for vertical downward output orientation in the WPWX installation guide for each shaft direction configuration.
■ X-Type Output Bearings Rated for Hanging Load
Output shaft bearings rated for the axial forces from hanging equipment loads below the downward output shaft.

All 5 shaft direction configurations (A–E) available for WPWX with X-type downward output.
■ Full WP Torque Range in Downward Configuration
WPWX rated for full WP output torques — up to 4,796 Nm at size 250 — in the X-type downward orientation across all 5 shaft direction configurations.

“WPWX universal X-type downward on our sub-floor and inverted drives. Universal body covers all our machine positions with downward output. Consistent quality across orders. Good practical product for sub-floor drive standardisation across multiple orientations.”
Germany 🇩🇪
“WPWX on our overhead conveyor downward output drives in multiple track positions. Universal body means one product for all track positions. X-type downward seal quality is excellent — no leaks despite the downward oil pressure on the seal face.”
China 🇨🇳
“WPWX universal downward output on our inverted mixer drives across multiple machine orientations. Universal body covers all positions with one product. Cast iron quality is excellent. Oil fill instructions for X-orientation across different shaft directions should be clearly documented per configuration.”
