WPW Universal Speed Cast Iron Worm Gearbox — WPW Series

Most worm gearbox catalogues offer orientation-specific housings: one model for horizontal input, another for vertical, another for overhead motors. When your equipment design requires a single gearbox that can be installed in any orientation — or when your machine range must standardise on one drive product across diverse installation positions — standard orientation-specific housings force you to stock and manage multiple models. The WPW Universal Speed Cast Iron Worm Gearbox solves this with the WPW-series universal body: 5 shaft direction configurations (A/B/C/D/E) in a single housing platform, covering all standard installation orientations from 1/5 to 1/60 reduction ratio, sizes 40–250 mm, with output torques up to 4,796 Nm. One product. Every orientation.

■ 5 Shaft Direction Configurations — A, B, C, D, E

The WPW-series universal body supports 5 standard shaft direction configurations, covering all practical installation orientations: A (standard horizontal), B (input from side), C (vertical upward output), D (input from above), E (reverse orientation). All configurations share the same housing casting.

■ Universal Oil System — Correct Lubrication in All Orientations

The WPW-series oil channels, fill ports, and vent positions are designed to maintain adequate worm mesh oil submersion across all 5 shaft direction configurations. Each configuration has orientation-specific fill quantities specified in the installation guide.

■ Full WP Ratio Range: 1/5–1/60 in All Orientations

All standard WP worm ratios (1/5, 1/7.5, 1/10, 1/15, 1/20, 1/25, 1/30, 1/40, 1/50, 1/60) are available across all 5 shaftdirection configurations — no ratio restrictions for any installation orientation.

■ FC20+ Cast Iron Universal Body — Full Mechanical Specification

The WPW universal body is manufactured from FC20+ grey cast iron to the same mechanical specification as the orientation-specific WP series housings. Universal versatility is achieved through geometry — not through any compromise of material quality.

■ Output Torques up to 4,796 Nm (Size 250 at 1/60)

The WPW provides the full WP series output torque range up to 4,796 Nm at size 250/ratio 1/60, covering all standard industrial drive applications from small process equipment to heavy industrial drives.

■ ISO 9001:2000 + CE Certified Across All Configurations

All 5 shaft direction configurations are covered by the WPW ISO 9001:2000 quality certification and CE declaration of conformity — providing complete procurement documentation for any installation orientation.

⚒ OEM Machine Builders — Multi-Orientation Product Range

OEM builders manufacturing the same machine for diverse customer installation environments use the WPW as their single drive platform — reducing the number of gearbox SKUs required across their product range from many to one.

⚔ Process Plant Standardisation

Large process plants managing hundreds of drive units across diverse orientations benefit from standardising on the WPW universal platform — simplifying spare parts inventory, training, and maintenance documentation.

☵ Conveyor Systems — Multiple Belt Orientations

Conveyor system integrators whose projects include horizontal, inclined, and vertical conveyor sections use the WPW to drive all sections with a single gearbox product, simplifying procurement and field spares.

⚊ Food & Beverage Multi-Line Installations

Food and beverage facilities with multiple processing lines in different orientations use the WPW to standardise their drive maintenance across all production lines.

⚛ General Manufacturing — Mixed Drive Environments

General manufacturing environments where machines of different types and orientations share a common spares holding benefit from the WPW’s universal mounting versatility.

✎ ISO 9001:2000 Certified

Every WPW is manufactured, assembled, and tested under ISO 9001:2000 quality management. Our factory was among the first in this product category to achieve this certification.

✎ CE Marking

Full CE marking confirms compliance with EU Machinery Directive 2006/42/EC — covering safety, design standards, and manufacturing quality for all WPW-series universal configurations.

✎ Pre-Shipment Testing

Noise test (below 72 dB(A) at rated load), oil leak test (30-minute pressurisation), torque transmission test (output torque within ±5% of rated). Failed units are reworked — not shipped.

✎ Universal Configuration Quality

Each shaft direction configuration (A–E) is verified dimensionally for correct bore position, keyway orientation, and oil channel routing before leaving our production line.

“WPW is our single gearbox specification across all conveyor projects. Horizontal sections, inclined sections, vertical sections — all WPW. Our spare parts holding went from 6 models to 1. The quality is consistent and the universal mounting genuinely works in every position we have installed.”

“We standardised our entire machine range on WPW. The 5-direction universal body was the key feature — our machines are installed at customer sites with diverse facility layouts requiring different drive orientations. One product standard for all sites. Excellent practical engineering.”

“WPW universal body on our food processing equipment. Multiple production lines with different orientations — one gearbox for all. Maintenance training simplified to one product. Quality consistent across all orders. Highly recommended for multi-orientation applications.”

“WPW universal on our diverse processing equipment. The 5-orientation capability eliminated 4 different gearbox models from our procurement list. Cast iron quality is excellent. Good practical product for standardisation across mixed-orientation installations.”
