Small Precison Worm Decrease Gearboxes
There are numerous of specifications you will need to consider when coming up with a worm gearbox selection.
First, what is the input and output torque requirements? Next, check vendor horsepower/torque charts and pick the correct worm gear reducer.
If how big is the gearbox will be an important consideration after that check the reducer dimension specifications, not all manufacturers make compact units. Actually, working with the right supplier will help you not only find the right equipment reducer but also avoid some of the most common errors in reducer selection. We provide a free guide to assist you find the right supplier to work with.
For low and fractional horsepower application we offer two sizes of worm gear reducer, the SW-1 and the SW-5. Size and torque output will be the major distinctions between both of these models. Both feature either a hollow or solid result shaft. Both versions are compact and offer 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 unique application or project is essential to selecting the right worm gearbox.

Using miniature gears, Ever-Power has designed and built exclusive, 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 custom micro gearboxes that are designed and built to meet your specific specifications.
Contact us for the mini gearbox the application requires, or demand a quote upon a customized micro gearbox.
Micro Gearbox Options
Gearboxes are also called reducers, gear reducers, velocity reducers, equipment drives, and gearmotors. All conditions can be used pretty much interchangeably. Please note that the links for our little gear drives include info on the full selection of frame sizes for that series or design.
Bevel Box Micro Equipment Drive
Our bevel container miniature equipment drives are application rated for the the best balance of overall performance and cost. Torque can be balanced to meet 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 amounts of thrust in a compact package. They offer an output shaft at 90° from the input, and so are available in equipment ratios from 1:1 to 40:1. Lightweight but durable, with machined light weight aluminum housings and hardened alloy steel 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 a few minutes of backlash or better. Also called “shaft to bore gearboxes,” these devices provide a single input shaft that protrudes from opposing sides of the housing; output is certainly a keyed bore. Regular solitary- and double-end shafts are available and supplied with keys and retainer rings. An array of gear ratios and insight sizes are available 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
