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 small worm gearbox output torque requirements? Next, check vendor horsepower/torque charts and pick the correct worm gear reducer.
If the size of the gearbox is going to be an important consideration after that check the reducer dimension specifications, not all manufacturers make compact units. In fact, working with the right supplier will help you not only find the right gear reducer but also avoid some of the most typical mistakes in reducer selection. We offer a free guide to assist you find the appropriate supplier to work with.
For low and fractional horsepower application we offer two sizes of worm gear reducer, the SW-1 and the SW-5. Size and torque output are the major differences between both of these models. Both feature either a hollow or solid output shaft. Both versions 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.

Using miniature gears, Ever-Power has designed and built exclusive, high accuracy mini gearboxes that can’t be found anywhere else. Our miniature gearboxes can be found in several configurations, which includes worm and wheel, cross axis helical, bevel, inline spur, and more. We can also provide customized micro gearboxes that were created and built to meet your specific specifications.
E mail us for the mini gearbox your application requires, or ask for a quote on a customized micro gearbox.
Micro Gearbox Options
Gearboxes are also known as reducers, gear reducers, speed reducers, gear drives, and gearmotors. All conditions can be used more or less interchangeably. Please note that the links for our small gear drives include info on the full range of frame sizes for that series or design.
Bevel Box Micro Gear Drive
Our bevel container miniature equipment drives are program rated for the ideal balance of efficiency and cost. Torque could be balanced to meet your RPM and working life requirements. Light-weight with low backlash overall 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 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 provide an output shaft at 90° from the input, and are available in gear ratios from 1:1 to 40:1. Lightweight but durable, with machined light weight aluminum housings and hardened alloy metal gears.
High efficiency: up to 88% at 1,000 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,” these devices provide a single input shaft that protrudes from opposing sides of the housing; output is a keyed bore. Standard single- and double-end shafts are available and given keys and retainer bands. An array of gear 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
