Small Precison Worm Reduction Gearboxes
There are numerous of specifications you will have to consider when making a worm gearbox selection.
First, what is the insight and output torque requirements? Next, check vendor horsepower/torque charts and pick the correct worm equipment reducer.
If the size of the gearbox will be an important consideration then check the reducer dimension specifications, not all manufacturers make small worm gearbox compact units. In fact, working with the proper supplier will help you not merely find the right gear reducer but also prevent some of the most typical mistakes in reducer selection. We offer a free guide to help you find the appropriate supplier to work with.
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 these two models. Both feature the hollow or solid output shaft. Both models 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 task is essential to selecting the correct worm gearbox.

Micro Gearbox Options
Gearboxes are also known as reducers, gear reducers, speed reducers, gear drives, and gearmotors. All terms can be used pretty much interchangeably. Please note that the links for our small gear drives include info on the full range of frame sizes for that series or style.
Bevel Box Micro Gear Drive
Our bevel box miniature gear drives are program rated for the optimum balance of efficiency and cost. Torque could be balanced to meet your RPM and operating life requirements. Lightweight with low backlash overall performance (as little as 1°, with option 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 amounts of thrust in a concise package. They offer an output shaft at 90° from the input, and so are obtainable in gear 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: only ≤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 called “shaft to bore gearboxes,” these devices provide a single input shaft that protrudes from reverse sides of the housing; output can be a keyed bore. Standard solitary- and double-end shafts can be found and given keys and retainer bands. 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
Obtainable in ratios from 5:1 to 120:1
Rated for input boosts to 3,000 RPM
Miniature 4 Shaft Worm Gearbox
Every miniature 4-shaft worm gearbox from Ever-Power features precision-machined hardened steel gears, solid aluminium housings, and long lasting lubrication. They offer two insight shafts on reverse sides of the framework, with two result shafts perpendicular to the input shafts. Our mini 4 shaft worm equipment drives deliver high effectiveness overall performance with low backlash.
High efficiency: up to 82% at 1,000 RPM
Low backlash: as little as ≈2°
Available with gear ratios from 1:1 to 32:1
Rated for input boosts to 4,000 RPM
Miniature Flange Worm Gear Drive
