Compact Worm Gearboxes

Worm Wheel Miniature Gearboxes

Our RW series miniature worm gear box assembly may be small, but it's tough enough to handle demanding power transfer applications. Constructed with machined aluminum housings and hardened steel input and output gears, they’ll deliver many years of reliable performance.

Available in three standard output ratios and with two output shaft diameter options, it’s easy to find the Ondrives.US right miniature gearbox for your needs. Each RW model worm gear box assembly provides proportionally high torque values (1.4 NM at 3,000 RPM) with very low backlash (maximum 2° backlash).
