WPWA Worm Reducer — Core Features

■ WPW Universal Body with A-Type Below Input

Universal P-housing with A-type (below) input shaft direction fixed. Provides the mounting versatility of the WPW body for applications where the A-type input orientation is specified.

■ Standard Worm Reducer in Universal Housing

WPWA delivers the familiar bilateral A-type solid input with the universal body’s multi-orientation mounting capability — the standard foot-mount reducer that can be mounted in 5 positions.

■ 11 Sizes: 40–250 mm, Output Torque to 4,440 Nm

Complete industrial drive range in the universal P-housing. Size 40 at 1/5 delivers 2.2 Nm; size 250 at 1/60 delivers 4,440 Nm.

■ FC20+ Cast Iron Universal P-Housing

Single-cast FC20+ grey cast iron P-housing provides 3× vibration damping versus aluminium and maintains shaft alignment across all 5 mounting orientations.

■ N150–N220 Lubrication — Optimised for Universal Housing

Lower viscosity lubricant than WP-series equivalents, optimised for the universal P-housing oil distribution geometry across all mounting orientations.

■ Bilateral A-Type Input — Motor from Either Side

Standard bilateral solid input shaft accepts motor connection from either side — maintaining full WPA-equivalent motor coupling flexibility within the universal housing.

WPWA Worm Reducer — Industry Applications

WPWA WPW universal worm reducer industry applications

⚒ OEM Machines Requiring Universal Mounting

Machine builders who need A-type input with universal mounting position flexibility use WPWA — one product accommodates all installation orientations without changing the reducer model.

⚊ Conveyor Drives with Multiple Mounting Options

Conveyor drive applications where the same A-type input reducer must be installed in different orientations (horizontal, wall-mount, inverted) standardise on WPWA for the universal body.

☷ Agricultural Equipment Standard Drive

Agricultural machines using standard A-type input worm reducers gain universal mounting flexibility with WPWA — fitting the same unit in multiple orientations on the same machine.

⚙ Process Equipment Universal A-Type Drives

Process equipment standardising on A-type input reducers uses WPWA for the universal body’s flexibility to accommodate changed installation orientations without a product change.

WPWA Universal Worm Reducer — Customer Reviews

★★★★★

“WPWA on our OEM machine. Universal body lets us fit the same reducer in three different mounting orientations across the machine. Standard A-type input — same motor couplings as our WPA units.”

Sydney — R.C.
★★★★★

“Used WPWA on our conveyor system. Multiple mounting positions, one product model with universal body. Standard A-type input works with our existing motor hardware.”

Melbourne — B.T.
★★★★★

“WPWA on our agricultural equipment. Universal body with A-type input — same reducer fitted in horizontal, wall-mount, and inverted positions. Significant inventory simplification.”

Toowoomba — D.R.
★★★★☆

“Good universal body A-type unit. WPWA-90 in multiple positions. Working well. Would appreciate a clear comparison chart between WPWA and WPA for our engineering selection.”

Auckland — K.H.

Frequently Asked Questions — WPWA Universal Speed Worm Reducer

▶ How does WPWA differ from WPA?
The WPA uses a fixed WP series housing specific to A-type input. The WPWA uses the universal P-housing which can accommodate multiple mounting orientations. Both have A-type bilateral solid input and the same torque ratings — the WPWA offers more installation flexibility.
▶ What mounting orientations does WPWA support?
The WPWA P-housing supports all 5 standard WPW mounting orientations: foot-mount horizontal (B3), output shaft upward (B6), output shaft downward (B7), reverse horizontal (B8), and wall-mount configurations.
▶ What lubricant is correct for WPWA?
N150–N220 for ambient below 40°C; N220–N320 for 40°C to 65°C. The WPWA uses the WPW lubrication specification — slightly lower viscosity than WP-series units.
▶ What is the maximum output torque for WPWA size 250?
WPWA size 250 delivers up to 4,440 Nm at 1/60 ratio — the same as WPW and WPA equivalent since the worm gear internals are identical.
▶ Can WPWA use standard WPA motor coupling hardware?
Yes. The WPWA A-type input shaft dimensions are compatible with standard WPA motor coupling hubs and adaptors — no new coupling hardware required when replacing WPA with WPWA.
