Small Precison Worm Decrease Gearboxes
There are many 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 equipment reducer.
If how big is the gearbox is going to be an important consideration then check the reducer dimension specifications, not all producers make compact units. Actually, working with the right supplier can help you not just find the right gear reducer but also prevent some of the most common mistakes in reducer selection. We provide a free guide to assist you find the appropriate 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 will be the major variations between both of these models. Both feature the hollow or solid result shaft. Both versions are compact and offer 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 essential to selecting the right worm gearbox.

Using miniature gears, Ever-Power provides designed and built exclusive, high accuracy mini gearboxes that cannot be found somewhere else. Our miniature gearboxes are available in numerous configurations, which includes worm and wheel, cross axis helical, bevel, inline spur, and more. We can also provide custom micro gearboxes that were created and built to meet your specific specifications.
Contact us for the mini gearbox your application requires, or ask for a quote upon a custom micro gearbox.
Micro Gearbox Options
Gearboxes are also called reducers, gear reducers, velocity reducers, gear drives, and gearmotors. All conditions can be used pretty much interchangeably. Please note 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 box miniature gear drives are software rated for the ideal balance of overall performance and price. Torque could be balanced to meet your RPM and working life requirements. Light-weight 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 are available in gear ratios from 1:1 to 40:1. Light-weight but durable, with machined 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 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 moments of backlash or better. Also known as “shaft to bore gearboxes,” the unit provide a single input shaft that protrudes from reverse sides of the casing; output is usually a keyed bore. Regular single- and double-end shafts can be found and supplied with keys and retainer bands. An array of gear ratios and input sizes are available to meet up your needs.
High efficiency: up to 86% at 1,000 RPM
Low backlash: ≤30 arc minutes or better
