Small Precison Worm Reduction Gearboxes
There are a number of specifications you will need to consider when coming up with a worm gearbox selection.
First, what is the insight and output torque requirements? Next, examine vendor horsepower/torque charts and select the correct worm equipment reducer.
If how big is the gearbox will likely be an important consideration then check the reducer dimension specs, not all producers make compact units. Actually, working with the right supplier will help you not just find the right gear reducer but also prevent some of the most typical mistakes in reducer selection. We provide a free guide to help you find the right supplier to work with.
For low and fractional horsepower application you can expect two sizes of worm equipment reducer, the SW-1 and the SW-5. Size and torque output will be the major variations between both of these models. Both feature the hollow or solid output shaft. Both models are compact and offer users a wide range of ratios, including:
SW-1, 3.5:1 to 60:1
SW-5, 5:1 to 100:1
Understanding the specs of your unique application or task is essential to selecting the correct worm gearbox.

Micro Gearbox Options
Gearboxes are also called reducers, gear reducers, rate reducers, equipment drives, and gearmotors. All terms can be used more or less interchangeably. Please be aware that the links for our little gear drives include information on the full selection of body sizes for that series or design.
Bevel Box Micro Equipment Drive
Our bevel box miniature gear drives are software rated for the the best balance of efficiency and cost. Torque can be balanced to meet your RPM and working life requirements. Lightweight with low backlash performance (as little as 1°, with option of 1/2”).
Result torque: up to 7 oz.-inches
Low backlash: ≈1°, option of 1/2”
Rated for input speeds up to 2,000 RPM
Temperature range: -5° to 175°F (-20° to 79°C); optional to -40°F (-40°C)
Cross Axis Helical Miniature Gearbox
Ever-Power miniature cross axis helical gearboxes provide relatively high levels of thrust in a compact package. They offer an result shaft at 90° from the input, and are available in gear ratios from 1:1 to 40:1. Light-weight but durable, with machined aluminium housings and hardened alloy metal gears.
High efficiency: up to 88% at 1,000 RPM
