Small Precison Worm Decrease Gearboxes
There are many of specifications you will have to consider when making a worm gearbox selection.
First, what is the insight and output torque requirements? Next, verify vendor horsepower/torque charts and pick the correct worm equipment reducer.
If how big is the gearbox will be an important consideration after that check the reducer dimension specs, not all producers make compact units. In fact, working with the proper supplier can help you not only find the right equipment reducer but also prevent some of the most common errors in reducer selection. We provide a free guide to help you find the right supplier to utilize.
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 are the major differences between these two models. Both feature the hollow or solid output shaft. Both versions are compact and offer users a wide selection of ratios, including:
SW-1, 3.5:1 to 60:1
SW-5, 5:1 to 100:1
Understanding the specifications of your unique application or task is vital to selecting the correct worm gearbox.

Using miniature gears, Ever-Power offers designed and built unique, high precision mini gearboxes that can’t be found somewhere else. Our miniature gearboxes are available in numerous configurations, including worm and wheel, cross axis helical, bevel, inline spur, and more. We can also provide customized micro gearboxes that are designed and created to meet your specific specifications.
Contact us for the mini gearbox your application requires, or demand a quote upon a custom micro gearbox.
Micro Gearbox Options
Gearboxes are also called reducers, gear reducers, speed reducers, equipment drives, and gearmotors. All terms can be used pretty much interchangeably. Please be aware that the links for our small gear drives include information on the full selection of frame sizes for that series or style.
Bevel Box Micro Equipment Drive
Our bevel box miniature gear drives are application rated for the optimum balance of functionality and cost. Torque could be balanced to meet your RPM and working life requirements. Light-weight with low backlash overall performance (less than 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 amounts of thrust in a compact package. They provide an result shaft at 90° from the input, and are available in gear small worm gearbox 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 a few minutes of backlash or better. Also called “shaft to bore gearboxes,” these devices provide a single insight shaft that protrudes from reverse sides of the casing; output is usually a keyed bore. Standard one- and double-end shafts are available and given keys and retainer rings. An array of gear ratios and insight sizes are available to meet your preferences.
High efficiency: up to 86% at 1,000 RPM
Low backlash: ≤30 arc minutes or better
