Small Precison Worm Decrease Gearboxes
There are numerous of specifications you will have to consider when coming up with a worm gearbox selection.
First, what’s the insight and output torque requirements? Next, check vendor horsepower/torque charts and pick the correct worm equipment reducer.
If how big is the gearbox will be an important consideration then check the reducer dimension specifications, not all producers make compact units. Actually, working with the proper supplier will help you not only find the right gear reducer but also prevent some of the most typical mistakes in reducer selection. We provide a 
free guide to help you find the appropriate supplier to work with.
For low and fractional horsepower application we offer two sizes of worm equipment reducer, the SW-1 and the SW-5. Size and torque output are 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 variety 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 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 many configurations, including worm and wheel, cross axis helical, bevel, inline spur, and more. We are able to also provide small worm gearbox Custom micro gearboxes that are designed and built to meet your unique specifications.
Contact us for the mini gearbox the application requires, or request a quote on 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 pretty much interchangeably. Please be aware that the links for our small gear drives include information on the full range of framework sizes for that series or design.
Bevel Box Micro Equipment Drive
Our bevel container miniature equipment drives are program rated for the the best balance of efficiency and cost. Torque can be balanced to meet your RPM and operating life requirements. Light-weight with low backlash functionality (less than 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 amounts of thrust in a compact package. They offer an result shaft at 90° from the input, and 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 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 called “shaft to bore gearboxes,” the unit provide a single input shaft that protrudes from opposite sides of the casing; output is definitely a keyed bore. Standard one- and double-end shafts can be found and given keys and retainer rings. An array of equipment ratios and insight sizes can be found to meet your needs.
High efficiency: up to 86% at 1,000 RPM
