Description
WPWE Double Speed Cast Iron Worm Reducer — Product Overview
The WP series uses fixed-direction housings — WPA for horizontal I/O, WPO for vertical-up output, WPX for vertical-down output. Each application direction requires a different housing. The WPWE changes this with the WPW universal housing body: a single standardised design that accommodates input and output connections from all five standard shaft directions. At the same time, dual worm stages extend the available ratio to 1/200–1/900+. One universal housing, any shaft direction, extreme ratio.

WPWE Double Speed Worm Reducer — Core Features
■ WPW Universal Body — 5 Shaft Directions at Extreme Ratio
The WPW-series universal housing body accepts input and output shaft connections from five different directions in a single standardised housing design. The WPWE extends this universal flexibility to dual-stage extreme ratios — 1/200 to 1/900+ in any of the WPW shaft configurations, without ordering a different gearbox family.
■ 5 Input/Output Direction Combinations — One Housing
The WPW body accommodates horizontal bilateral, top-entry, front-entry, and vertical output shaft configurations in a single housing design — reducing inventory complexity for OEMs with multiple installation orientations.
■ Same 6,050 Nm Torque — Universal Body Does Not Reduce Capacity
The WPW universal housing maintains the same worm gear torque ratings as the standard WPE housing variants. WPWE size 155–250 delivers 6,050 Nm.
■ Dual Independent Oil Chambers — Both Stages
Two independently sealed chambers with separate fill, gauge, and drain. Oil volumes are specified per shaft direction in the WPW lubrication table.
■ FC20+ Dual-Chamber Cast Iron Universal Housing
Single-cast FC20+ grey cast iron dual-chamber design maintains inter-stage alignment across all shaft direction configurations.
■ WPW Universal Body Simplifies OEM Inventory
Using a single WPWE universal body to cover multiple shaft direction requirements reduces the number of different gearbox models an OEM must stock — simplifying purchasing, warehousing, and spare parts management.
WPWE Worm Reducer — Industry Applications

⚒ Multi-Direction OEM Machine Drives
OEM machine builders with multiple drive shaft direction requirements use WPWE as a single universal extreme-ratio platform — one product family covers horizontal, vertical, and angled drive configurations without changing gearbox type.
⚊ Packaging Machinery Extreme Ratio Drives
Packaging line drives requiring ultra-low output speeds (below 5 rpm) use WPWE universal body for flexible motor and load shaft direction configuration within the machine frame — no custom brackets or direction-specific reducers.
⚙ Multi-Orientation Processing Equipment
Food processing and pharmaceutical equipment with drives in multiple mounting orientations use WPWE to standardise on one universal reducer model across the full machine — simplifying spare parts and maintenance training.
☷ Agricultural Equipment Slow Drives
Agricultural machinery requiring slow-speed drives (spreaders, seeders, irrigation mechanisms) in various shaft configurations uses WPWE universal body at extreme ratios — one reducer model for all drive positions on the same machine.

Both housings carry FC20 mill certificates: 220 MPa minimum tensile strength, 160–200 HB hardness. Ultrasonic testing on size combinations 135–200 and above.
WPWE Double Speed Worm Reducer — Customer Reviews
“WPWE on our packaging line drives. WPW universal body means one reducer model covers three different drive shaft directions in our machine. 1/500 ratio, correct output speed, flexible installation.”
“Used WPWE on our food processing equipment. Universal body at extreme ratio — one spare part covers all drive positions on the line. Simplified our maintenance inventory significantly.”
“WPWE for our agricultural spreader drives. Multiple shaft directions on the same machine covered by one WPWE model. Double-stage ratio gives us the correct slow spread rate directly from a standard motor.”
“Good universal body double-stage unit. WPWE-70–120 covering multiple orientations on our OEM machine. Would appreciate a comprehensive shaft direction selection guide in the product documentation.”
