Small Precison Worm Reduction Gearboxes
There are a variety of specifications you will have to consider when making a worm gearbox selection.
First, what’s the insight and output torque requirements? Next, examine vendor horsepower/torque charts and select the correct worm gear reducer.
If the size of the gearbox will probably be an important consideration after that check the reducer dimension specs, not all manufacturers make compact units. Actually, working with the right supplier will help you not only find the right equipment reducer but also prevent some of the most common errors in reducer selection. We offer a free guide to help you find the right supplier to work with.
For low and fractional horsepower software we offer two sizes of worm gear reducer, the SW-1 and the SW-5. Size and torque output are 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 specs of your particular application or task is vital to selecting the right worm gearbox.

Micro Gearbox Options
Gearboxes are also called 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 details on the full range of frame sizes for that series or design.
Bevel Box Micro Equipment Drive
Our bevel container miniature equipment drives are program rated for the the best possible balance of overall performance and cost. Torque can be balanced to meet your RPM and operating life requirements. Lightweight with low backlash overall performance (less than 1°, with choice of 1/2”).
Result torque: up to 7 oz.-inches
Low backlash: ≈1°, option of 1/2”
Rated for input boosts 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 provide an result shaft at 90° from the input, and so are small worm gearbox Obtainable in gear 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

“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 input shaft that protrudes from opposing sides of the housing; output is a keyed bore. Standard one- and double-end shafts are available and given keys and retainer rings. An array of equipment ratios and input sizes can be found to meet your preferences.
High efficiency: up to 86% at 1,000 RPM
Low backlash: ≤30 arc minutes or better
