WPW Universal Speed Cast Iron Worm Reducer — WPW Series

The WPW P-housing is machined to accept input and output shaft connections from five standard directions — A (below), S (above), O (vertical upward output), X (vertical downward output), and T (side output). One housing design serves every standard installation orientation.

The WPW P-housing accommodates all five standard shaft direction configurations in a single casting — eliminating the need for direction-specific housing variants. Input power from 0.06 kW (size 40) to 98 kW (size 250), output torques from 2.2 Nm to 4,440 Nm across 11 standard sizes.

■ WPW P-Housing — 5 Shaft Direction Configurations

The WPW P-housing is machined to accept input and output shaft connections from five standard directions — A (below), S (above), O (vertical upward output), X (vertical downward output), and T (side output). One housing design serves every standard installation orientation.

■ Ratio 1/5–1/60 — Standard Single-Stage Range

Covers the full single-stage worm reducer ratio range. Size 40 at 1/5 delivers 2.2 Nm; size 250 at 1/60 delivers 4,440 Nm — all from the same universal housing geometry.

■ 11 Frame Sizes: 40–250 mm

From compact 6.5 kg size 40 mechanism drives to 430 kg heavy-duty size 250 industrial drives — 11 standard sizes covering the full range of industrial and agricultural drive requirements.

■ FC20+ Cast Iron Universal Housing — Vibration Damping

The P-housing is machined from a single FC20+ grey cast iron casting. Vibration damping 3× superior to aluminium equivalents — suitable for high-shock conveyor and agricultural applications.

■ N150–N220 Lubrication — Wider Low-Temperature Range

WPW uses N150–N220 mineral oil for ambient below 40°C — a lower viscosity than the WP series N220–N320, reflecting the WPW’s optimised shaft direction flexibility and oil distribution geometry.

■ Bilateral Input Shaft — Motor from Either Side

The bilateral input shaft accepts motor coupling connections from either side of the P-housing without ordering a mirrored unit — installation flexibility regardless of which of the 5 shaft directions is selected.

⚒ Multi-Orientation OEM Machine Builds

OEM machine builders with drive requirements in multiple shaft directions use WPW as a single universal product — one housing covers all installation geometry requirements across the machine.

⚊ Packaging Line Universal Drives

Packaging machines with drives in various orientations standardise on WPW universal body — horizontal conveyor drives, vertical lifts, and side drives all served by one product.

☷ Agricultural Equipment Versatile Drives

Farm equipment with drives in multiple positions — ground engagement, lateral spreader, and overhead fan drives — uses WPW to minimise the number of different gearbox types on the machine.

⚙ Industrial Process Equipment

Process equipment requiring speed reduction in varied installation orientations standardises on WPW for simplified spare parts inventory and maintenance training.

■ ISO 9001:2000 Certified Production

Every WPW unit is manufactured under ISO 9001:2000 quality management. Raw material inspection, in-process checks, and final testing are documented and traceable.

■ CE Marking — EU Machinery Directive 2006/42/EC

Full CE compliance for export to EU, UK, Australian, and New Zealand markets.

■ Pre-Shipment Testing: Noise, Leak, Torque

Noise below 68 dB(A) at rated load, 30-minute pressurisation leak test, and output torque within ±5% of rated. Non-conforming units reworked before shipment.

■ FC20+ Material Certification

Housing castings verified by mill certificates: minimum 220 MPa tensile strength, 160–200 HB hardness.

“WPW on our OEM packaging machine. Universal P-housing covers horizontal conveyor, vertical lift, and side output drives on the same machine with one product model. Eliminated three different gearbox types from our BOM.”

“Used WPW on our agricultural equipment. Multiple drive positions, one WPW model. Standard motor coupling hardware works on all positions. Simplified our spare parts inventory significantly.”

“WPW on our food processing line. Universal body handles all our drive orientations — IEC flange, standard coupling, all in one housing. Maintenance team only needs to know one unit.”

“Good universal reducer. WPW-90 covering three different orientations on our conveyor system. Would appreciate a published shaft direction selection guide to simplify configuration ordering.”
