Small Precison Worm Reduction Gearboxes
There are a number of specifications you will need to consider when coming up with a worm gearbox selection.
First, what is the insight and output torque requirements? Next, check vendor horsepower/torque charts and select the correct worm gear reducer.
If how big is the gearbox will likely be an important consideration then check the reducer dimension specifications, not all manufacturers make compact units. In fact, working with the proper supplier will help you not only find the right gear reducer but also avoid some of the most typical errors in reducer selection. We provide a free guide to help you find the right 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 differences between these two models. Both feature either a hollow or solid output shaft. Both models are compact and provide users an array of ratios, including:
SW-1, 3.5:1 to 60:1
SW-5, 5:1 to 100:1
Understanding the specifications of your particular application or task is vital to selecting the correct worm gearbox.

Using small worm gearbox miniature gears, Ever-Power has designed and built exclusive, high accuracy mini gearboxes that cannot be found somewhere 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 are designed and built to meet your unique specifications.
Contact us for the mini gearbox the application requires, or ask for a quote on a customized micro gearbox.
Micro Gearbox Options
Gearboxes are also known as reducers, gear reducers, acceleration reducers, equipment drives, and gearmotors. All conditions can be used pretty much interchangeably. Please note that the links for our small gear drives include info on the full selection of body sizes for that series or style.
Bevel Box Micro Equipment Drive
Our bevel package miniature equipment drives are software rated for the the best balance of functionality and cost. Torque can be balanced to meet up your RPM and operating life requirements. Lightweight 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”
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 are available in gear ratios from 1:1 to 40:1. Lightweight but durable, with machined aluminum housings and hardened alloy metal gears.
High efficiency: up to 88% at 1,000 RPM
Low backlash: as low as ≤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 mins 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 housing; output is definitely a keyed bore. Standard one- and double-end shafts are available and supplied with keys and retainer rings. 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
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 steel gears, solid aluminium housings, and permanent lubrication. They provide two insight shafts on reverse sides of the framework, with two output shafts perpendicular to the insight shafts. Our mini 4 shaft worm equipment drives deliver high efficiency overall performance with low backlash.
