Small Precison Worm Reduction Gearboxes
There are a variety of specifications you will have to consider when coming up with a worm gearbox selection.
First, what is the input and output torque requirements? Next, verify vendor horsepower/torque charts and pick the correct worm gear reducer.
If the size of the gearbox will likely be an important consideration after that check the reducer dimension specs, not all manufacturers make compact units. In fact, working with the right supplier can help you not merely find the right gear reducer but also prevent some of the most typical mistakes in reducer selection. We offer a free guide to assist you find the appropriate supplier to utilize.
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 will be 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 small worm gearbox selection 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 essential to selecting the correct worm gearbox.

Using miniature gears, Ever-Power provides designed and built unique, high accuracy 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 are able to also provide custom micro gearboxes that were created and built to meet your specific specifications.
Contact us for the mini gearbox your application requires, or request a quote on a customized micro gearbox.
Micro Gearbox Options
Gearboxes are also called reducers, gear reducers, velocity reducers, gear 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 Gear 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 working life requirements. Light-weight with low backlash overall performance (less than 1°, with choice 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 concise package. They provide an result 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 light weight aluminum housings and hardened alloy steel 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 moments of backlash or better. Also called “shaft to bore gearboxes,” the unit provide a single input shaft that protrudes from reverse sides of the casing; output is a keyed bore. Standard single- and double-end shafts can be found and supplied with keys and retainer rings. An array of gear ratios and insight sizes can be found 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 speeds up to 3,000 RPM
Miniature 4 Shaft Worm Gearbox
Every miniature 4-shaft worm gearbox from Ever-Power features precision-machined hardened metal gears, solid aluminium housings, and permanent lubrication. They provide two input shafts on opposite sides of the framework, with two output shafts perpendicular to the input shafts. Our mini 4 shaft worm equipment drives deliver high performance performance with low backlash.
