Small Precison Worm Reduction Gearboxes
There are many of specifications you will have to consider when making 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 the size of the gearbox will be an important consideration then check the reducer dimension specs, not all producers make compact units. Actually, working with the right supplier can help you not only find the right gear reducer but also prevent some of the most typical errors in reducer selection. We offer a free guide to help you find the right supplier to utilize.
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 differences between these two models. Both feature either a hollow or solid result shaft. Both models are compact and provide users a wide selection 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 vital to selecting the correct worm gearbox.

Using miniature gears, Ever-Power offers designed and built exclusive, high precision mini gearboxes that cannot be found somewhere 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 customized micro gearboxes that were created and created 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, 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 range of body sizes for that series or style.
Bevel Box Micro Gear Drive
Our bevel container miniature gear drives are software rated for the maximum balance of overall performance and price. Torque could be balanced to meet up your RPM and operating life requirements. Light-weight with low backlash performance (as little as 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 levels of thrust in a concise package. They offer an output shaft at 90° from the input, and are available in equipment ratios from 1:1 to 40:1. Lightweight but long lasting, with machined aluminium housings and hardened alloy metal 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 mins of backlash or better. Also known as “shaft to bore gearboxes,” the unit provide a single insight shaft that protrudes from opposite sides of the housing; output can be a keyed bore. Regular one- and double-end shafts are available and given keys and retainer rings. An array of equipment ratios and input sizes are obtainable to meet up your needs.
High efficiency: up to 86% at 1,000 RPM
Low backlash: ≤30 arc minutes or better
