Small Precison Worm Decrease Gearboxes
There are a number of specifications you will need to consider when coming up with a worm gearbox selection.
First, what’s the insight and output torque requirements? Next, check vendor horsepower/torque charts and pick the correct worm gear reducer.
If the size of the gearbox will likely be an important consideration then check the reducer dimension specs, not all manufacturers make compact units. Actually, working with the proper supplier will help you not only find the right gear reducer but also avoid some of the most common errors in reducer selection. We provide a free guide to assist you find the appropriate supplier to work with.
For low and fractional horsepower application you can expect two sizes of worm gear reducer, the SW-1 and the SW-5. Size and torque output are the major variations between both of these models. Both feature either a hollow or solid output shaft. Both models are compact and provide users a wide variety 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 project is vital to selecting the correct worm gearbox.

Micro Gearbox Options
Gearboxes are also called reducers, gear reducers, speed reducers, gear drives, and gearmotors. All terms can be used pretty much interchangeably. Please note that the links for our small gear drives include info on the full selection of framework sizes for that series or style.
Bevel Box Micro Equipment Drive
Our bevel box miniature gear drives are app rated for the the best balance of efficiency and price. Torque can be balanced to meet up your RPM and working life requirements. Light-weight with low backlash overall performance (less than 1°, with option of 1/2”).
Output torque: up to 7 oz.-inches
Low backlash: ≈1°, option of 1/2”
Rated for input boosts 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 output shaft at 90° from the input, and so are available in gear ratios from 1:1 to 40:1. Lightweight but long lasting, with machined aluminium housings and hardened alloy metal gears.
High efficiency: up to 88% at 1,000 RPM
Low backlash: only ≤30 arc minutes
Rated for input boosts to 4,000 RPM
“Left hand” models available
Miniature 2 Shaft Worm Gearbox
Our miniature 2 shaft worm gearmotors are engineered for ≤30 arc mins of backlash or better. Also known as “shaft to bore gearboxes,” the unit provide a single insight shaft that protrudes from opposite sides of the casing; output is a keyed bore. Standard one- and double-end shafts can be found and given keys and retainer rings. An array of equipment ratios and input sizes are available to meet your needs.
High efficiency: up to 86% at 1,000 RPM
Low backlash: ≤30 arc minutes or better
Obtainable in ratios from 5:1 to 120:1
Rated for input boosts to 3,000 RPM
Miniature 4 Shaft Worm Gearbox
Every miniature 4-shaft worm gearbox from Ever-Power features precision-machined hardened steel gears, solid aluminium housings, and long term lubrication. They provide two insight shafts on reverse sides of the body, with two result shafts perpendicular to the insight shafts. Our mini 4 shaft worm gear drives deliver high effectiveness efficiency with low backlash.
