Small Precison Worm Reduction Gearboxes
There are numerous of specifications you will have to consider when coming up with a worm gearbox selection.
First, what’s the input and output torque requirements? Next, examine vendor horsepower/torque charts and pick the correct worm gear reducer.
If how big is the gearbox will probably be an important consideration then check the reducer dimension specs, not all producers make compact units. In fact, working with the right supplier will help you not merely find the right equipment reducer but also avoid 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 program you can expect 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 output shaft. Both models are compact and provide users a wide variety 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 project is vital to selecting the right worm gearbox.

Using miniature gears, Ever-Power has designed and built unique, high accuracy mini gearboxes that can’t be found somewhere else. Our miniature gearboxes can be found in many 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 built to meet your unique specifications.
E mail us for the mini gearbox the application requires, or ask for a quote upon a custom micro gearbox.
Micro Gearbox Options
Gearboxes are also known as reducers, gear reducers, quickness reducers, gear drives, and gearmotors. All terms can be used more or less interchangeably. Please be aware that the links for our small gear drives include details on the full selection of frame sizes for that series or style.
Bevel Box Micro Equipment Drive
Our bevel box 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 overall performance (as little as 1°, with choice 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 compact package. They offer 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 aluminium housings and hardened alloy steel gears.
High efficiency: up to 88% at 1,000 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 called “shaft to bore gearboxes,” these devices provide a single insight shaft that protrudes from opposing sides of the casing; output is usually a keyed bore. Standard single- and double-end shafts are available and supplied with keys and retainer rings. An array of equipment ratios and input sizes are available to meet your preferences.
High efficiency: up to 86% at 1,000 RPM
Low backlash: ≤30 arc minutes or better
