Small Precison Worm Decrease Gearboxes
There are many of specifications you will need 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 gear reducer.
If how big is the gearbox is going to 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 merely find the right equipment reducer but also prevent some of the most typical errors in reducer selection. We offer a free guide to assist you find the appropriate supplier to work with.
For low and fractional horsepower app you can expect two sizes of worm equipment reducer, the SW-1 and the SW-5. Size and torque output are the major distinctions between these two models. Both feature either a hollow or solid result 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 specs of your particular application or project is vital to selecting the right worm gearbox.

Using miniature gears, Ever-Power has designed and built exclusive, high precision mini gearboxes that cannot be found somewhere else. Our miniature gearboxes are available in several configurations, which includes worm and wheel, cross axis helical, bevel, inline spur, and more. We can also provide custom micro gearboxes that are designed and created to meet your unique specifications.
E mail us for the mini gearbox your application requires, or ask for a quote on a custom micro gearbox.
Micro Gearbox Options
Gearboxes are also called reducers, gear reducers, quickness reducers, equipment drives, and gearmotors. All terms can be used more or less interchangeably. Please note that the links for our small 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 equipment drives are application rated for the optimum balance of performance and cost. Torque can be balanced to meet up your RPM and operating life requirements. Light-weight with low backlash overall performance (as little as 1°, with option of 1/2”).
Output torque: up to 7 oz.-inches
Low backlash: ≈1°, option of 1/2”

“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,” the unit provide a single insight shaft that protrudes from reverse sides of the housing; output is usually a keyed bore. Standard single- and double-end shafts are available and supplied with keys and retainer bands. An array of gear ratios and insight sizes can be found to meet your preferences.
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
