Small Precison Worm Reduction Gearboxes
There are numerous 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, verify vendor horsepower/torque charts and select the correct worm gear reducer.
If the size of the gearbox will probably be an important consideration after that check the reducer dimension specifications, not all producers make compact units. Actually, working with the right supplier can help you not only find the right equipment reducer but also prevent some of the most typical mistakes in reducer selection. We offer a free guide to assist 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 variations between these two models. Both feature the hollow or solid result shaft. Both versions 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 specs of your particular application or task is essential to selecting the right 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 numerous configurations, including 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 the application requires, or demand a quote upon a custom micro gearbox.
Micro Gearbox Options
Gearboxes are also called reducers, gear reducers, rate reducers, equipment drives, and gearmotors. All terms can be used more or less interchangeably. Please note that the links for our little gear drives include info on the full selection of frame sizes for that series or style.
Bevel Box Micro Equipment Drive
Our bevel container miniature equipment drives are application 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 functionality (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 levels of thrust in a concise package. They offer an output shaft at 90° from the input, and so are obtainable in gear ratios from 1:1 to 40:1. Lightweight but long lasting, with machined 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 speeds up 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 opposing sides of the housing; output is certainly a keyed bore. Standard one- 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 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 boosts 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 long lasting lubrication. They provide two insight shafts on opposing sides of the framework, with two result shafts perpendicular to the input shafts. Our mini 4 shaft worm equipment drives deliver high efficiency overall performance with low backlash.
