WPDX D+X Inverted Drive Cast Iron Worm Reducer — Product Overview
Ceiling-mounted and inverted overhead drive applications demand two things beyond the standard WPX: direct motor mounting without an adaptor plate, and maintenance access without bringing the unit down from the ceiling. The WPDX delivers both. The integrated IEC motor flange eliminates the adaptor. The D-type split housing allows the cover to be removed and the worm wheel inspected while the unit remains ceiling-mounted and the motor stays connected.
Output torques up to 3,025 Nm across 12 standard sizes make the WPDX the reference choice for overhead mining conveyors, industrial process line ceiling drives, and hanging drive systems where maintenance accessibility and direct motor mounting are both required.

WPDX Worm Reducer — Core Features
■ X-Type Downward Output — Purpose-Built Inverted Drive
Vertical downward output shaft is standard — no inverted mounting kit, no right-angle adapter. Mount the housing ceiling-up, output shaft points directly to the driven equipment below.
■ D-Type Split Housing — Ceiling-Position Maintenance
Cover removal in the ceiling-mounted position without lowering the unit. Worm wheel access with motor still connected and unit still on the ceiling structure — critical for reducing planned maintenance downtime.
■ IEC Motor Flange — No Adaptor Plate Required
Integrated IEC 72-1 flange eliminates the motor adaptor from the overhead drive BOM. Four motor bolts, drive complete — no coupling, no alignment, no adaptor fabrication.
■ Output Torque to 3,025 Nm — Same as WPDA
D+X configuration does not affect worm gear capacity. WPDX size 250 delivers 850–3,025 Nm identical to the WPDA.
■ FC20+ Cast Iron — Rigid Under Inverted Load
Cast iron housing maintains dimensional stability in inverted ceiling-mount configurations under the sustained weight of the drive unit and motor — aluminium housings can creep under long-term overhead load.
■ Weight 5–396 kg, 12 Sizes
From compact size 40 (5 kg) to heavy-duty size 250 (396 kg) — the full industrial overhead drive power range in a single WPDX product series.
WPDX Worm Reducer — Industry Applications

⚊ Mining Overhead Conveyor Drives
WPDX ceiling-mount with IEC motor and downward shaft drives mining conveyor heads directly from above. D-split cover enables in-position inspection during maintenance windows without dismounting from the structure.
⚒ Industrial Process Line Ceiling Drives
Automotive and electronics assembly lines with overhead conveyor systems benefit from WPDX direct-motor ceiling drive — eliminates floor-level obstructions and simplifies plant layout.
☷ Hanging Drive Systems
For monorail, drag chain, and hanging conveyor systems, WPDX ceiling-mount configuration with downward output provides the most mechanically efficient drive arrangement.
⚙ Overhead Crane & Hoist Auxiliary Drives
WPDX auxiliary drives for crane traversal and hoist mechanisms benefit from the inverted IEC motor flange and downward output shaft — compact, direct, and serviceable in position.

WPDX Worm Reducer — Customer Reviews
“WPDX on our ceiling-mounted overhead conveyor drives. IEC motor bolts on from the side, X-type shaft points down to the conveyor head. D-split cover opens for inspection while unit stays ceiling-mounted.”
“Used WPDX-120 on inverted drives in our continuous process line. Direct IEC motor flange, downward output, split maintenance access in place — exactly what an overhead drive should be.”
“WPDX on our hanging gravity feed drives. D+X combination gave us the most compact overhead drive envelope with full maintenance access from below — no need to lower the unit for inspection.”
“Good D+X combination for ceiling applications. Motor mounts direct, downward shaft output, split housing opens in position. Would appreciate a size 165 to fill the gap between 155 and 175.”
