Small Precison Worm Decrease Gearboxes
There are many of specifications you will need to consider when making a worm gearbox selection.
First, what’s the insight and output torque requirements? Next, verify vendor horsepower/torque charts and pick the correct worm gear reducer.
If how big is the gearbox will probably be an important consideration then check the reducer dimension specs, not all producers make compact units. In fact, working with the proper supplier can help you not merely find the right equipment reducer but also prevent some of the most typical mistakes in reducer selection. We offer a free guide to help you find the appropriate 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 either a hollow or solid output shaft. Both versions are compact and offer 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 particular application or task is vital to selecting the right worm gearbox.

Using miniature gears, Ever-Power offers designed and built exclusive, high accuracy mini gearboxes that can’t be found somewhere else. Our miniature gearboxes can be found in many configurations, which includes worm and wheel, cross axis helical, bevel, inline spur, and more. We can also provide custom micro gearboxes that were created and created to meet your specific specifications.
Contact us for the mini gearbox the application requires, or ask for a quote on a custom micro gearbox.
Micro Gearbox Options
Gearboxes are also called reducers, gear reducers, swiftness reducers, gear drives, and gearmotors. All terms can be used more or less interchangeably. Please be aware that the links for our little gear drives include info on the full selection of body sizes for that series or style.
Bevel Box Micro Equipment Drive
Our bevel container miniature gear drives are program rated for the the best balance of functionality and cost. Torque could be balanced to meet up your RPM and working life requirements. Lightweight with low backlash efficiency (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 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 concise package. They offer an result shaft at 90° from the input, and are obtainable in gear ratios from 1:1 to 40:1. Lightweight but long lasting, with machined aluminium housings and hardened alloy steel gears.
High efficiency: up to 88% at 1,000 RPM
Low backlash: only ≤30 arc minutes
Rated for input speeds up to 4,000 RPM
“Left hand” models available
Miniature 2 Shaft Worm Gearbox
Our miniature 2 shaft worm gearmotors are engineered for ≤30 arc moments of backlash or better. Also known as “shaft to bore gearboxes,” these devices provide a single insight shaft that protrudes from reverse sides of the casing; output is certainly a keyed bore. Standard one- and double-end shafts can be found and given keys and retainer bands. An array of equipment ratios and input sizes can be found to meet your needs.
High efficiency: up to 86% at 1,000 RPM
Low backlash: ≤30 arc minutes or better
Available in ratios from 5:1 to 120:1
