The WP series worm gearbox is a right-angle speed reducer built around a hardened steel worm and a tin-bronze worm wheel, supplied in centre distances from 40 to 250 mm. It is the practical choice for general machinery, light conveyors, packaging equipment and positioning drives where a compact, quiet and self-locking reduction stage is needed at modest cost.
Standard single-stage ratios run from 5:1 to 100:1, and the range covers foot-mounted, flange-mounted, shaft-mounted and universal housings so the same gearbox can be dropped into new builds or used as a direct replacement on existing equipment. Cast iron housings are used across the range for stiffness and heat dissipation; aluminium housings are available on the smaller frames where weight matters. Input shafts, output shafts and hollow output bores can be specified to match the motor and the driven machine.
Worm gearing runs quietly and, at higher ratios, resists back-driving — useful on hoists, tilting mechanisms and inclined conveyors where holding the load without an additional brake simplifies the design. Because the sliding contact generates more heat than helical gearing, we check the duty cycle, ambient temperature and thermal rating before confirming a frame size, and we recommend the correct lubricant grade for the operating temperature.
Every unit is supplied as a complete, run-tested assembly with the ratio, mounting position, shaft direction and motor adaptation confirmed against your data before release. We can also combine the gearbox with an IEC motor, a brake motor or a variable-frequency drive as one shipment. Lead time is confirmed against the specific configuration at quotation, and spare worm wheels, seals and bearings remain available for the service life of the unit.
Send us your input speed, required output speed, torque or motor power, mounting position and operating hours. We will match a frame, confirm the thermal rating and return a complete selection with a quotation.
