Description
WPW Universal Speed Worm Gear Reducer — Multi-Orientation Flanged-Base Drive for Food, Packaging & General Industry
Most industrial worm gearboxes require careful orientation selection at the design stage — once a standard foot-mount unit is installed, it cannot be repositioned without oil level reconfiguration and potential housing modifications. The WPW universal speed worm gear reducer breaks this constraint with a flanged-base design incorporating multiple anchor bolt positions and multi-face oil ports that ensure correct lubrication in any of the five standard mounting orientations (A–E) plus non-standard angles.
This installation flexibility — combined with the same cast iron build quality, precision worm-and-wheel gearing, and ISO-standard ratio range (1/5–1/60) found in the WP series — makes the WPW the preferred choice for food processing conveyors, packaging machinery, and general industry applications where the mounting angle is constrained by the machine layout rather than the gearbox specification. Available in 12 sizes (40–250 mm), ratios 1/5 to 1/60, output torque up to 2,371 Nm. About Ever-power | Request a Selection Guide

✅ Key Features & Benefits
True Multi-Orientation Universal Mounting
The WPW can be anchored in any of five standard positions with correct oil lubrication confirmed for each — not simply a standard gearbox rotated at will. The multi-face oil port system, precision-flat base arms, and anchor bolt layout are all engineered for multi-orientation service. Keywords: universal mount worm gear reducer, multi-orientation flanged-base worm gearbox.
Flanged Anchor Base — More Rigid Than Foot-Mount
The four-point anchor bolt base distributes mounting reaction torques over a wider footprint than a two-pad foot-mount, reducing concentrated bolt stresses and minimising vibration transmission to the supporting structure — a meaningful advantage for food processing and packaging machinery where vibration affects product quality.
Precision Worm & Wheel — Low Noise, High Efficiency
Ground 20CrMnTi worm and ZCuSn10Pb1 bronze wheel to ISO 1328 Grade 7 tolerances deliver smooth, quiet drive (≤72 dB(A) at rated load) with efficiency 60–90% depending on ratio. Self-locking at ratios ≥1/30 provides passive load holding without a separate brake.
Design Flexibility — Same Gearbox, Multiple Machine Layouts
OEM machine designers can specify a single WPW size across multiple machine variants that differ only in drive orientation — eliminating the need to stock and manage separate WPA (vertical), WPX (dual), and WPS (finned) variants for each machine configuration.
12 Sizes — Full Industrial Range
Twelve sizes (40–250 mm) covering input powers up to 33 kW and output torques up to 2,371 Nm at 1500 r/min provide the complete range of industrial drive requirements from small packaging machine drives to large conveyor head drives.
Self-Locking for Safe Load Holding
At ratios of 1/30 and above, the WPW provides reliable static self-locking — holding connected loads securely when the motor is de-energised. This passive safety feature is valuable for inclined conveyors, elevating equipment, and packaging machine axis drives.

❓ Frequently Asked Questions
What makes the WPW ‘universal’ compared to a standard WP gearbox?
The standard WP series has a two-pad foot-mount base designed primarily for horizontal installation. The WPW has an integral flanged base with four anchor bolt positions and multi-face oil ports, allowing correct installation in horizontal, vertical, inclined, and wall-mount orientations without oil level adjustment tools or housing modifications. The WPW housing also accepts oil fill from the correct face for each orientation, ensuring both gear mesh and bearing lubrication regardless of mounting angle.
How many mounting orientations does the WPW support?
The WPW supports five standard shaft-direction positions (A–E) covering horizontal foot-mount, vertical shaft-up, vertical shaft-down, and inclined orientations. Non-standard angles can be accommodated — contact us with your specific mounting angle and we will confirm the correct oil fill position and anchor bolt torque specification.
What anchor bolt specification should I use for WPW installation?
The Z×L column in the specification table defines the recommended anchor bolt for each size. For example, size 70 uses M10×25 (M10 diameter, 25 mm embedment); size 135 uses M16×35. All four base arm holes are the same specification for a given size. For concrete foundation mounting, use anchor sleeves with the specified bolt size. Contact us for specific torque recommendations for your base material.
Can the WPW be used in food processing environments?
Yes — the WPW is widely used in food processing conveyor drives. For food safety compliance, specify: (1) NSF H1 food-grade lubricant (factory-fill option available), (2) epoxy coating for the external housing if wet wash-down is required, and (3) stainless steel external hardware. Contact us for a food-grade WPW specification for your specific food production environment.
What is the maximum output torque of the WPW?
At 1500 r/min input, size 250 at ratio 1/60 delivers approximately 2,371 Nm output torque (from the WP.WPK.WPW(A.S.X.O.T.V) power and torque table). For size 200 at ratio 1/60 approximately 1,449 Nm; size 135 at ratio 1/50 approximately 626 Nm. Contact our engineers with your required input power and ratio for a precise torque calculation.
