Small Precison Worm Reduction Gearboxes
There are a variety of specifications you will need to consider when making a worm gearbox selection.
First, what is the input and output torque requirements? Next, verify 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 manufacturers make compact units. In fact, working with the proper supplier will help you not merely find the right gear reducer but also avoid some of the most common 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 variations between both of these models. Both feature the hollow or solid output shaft. Both versions are compact and offer users a wide range 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 correct worm gearbox.

Micro Gearbox Options
Gearboxes are also called reducers, gear reducers, acceleration reducers, equipment 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 framework sizes for that series or design.
Bevel Box Micro Gear Drive
Our bevel package miniature equipment drives are program rated for the the best balance of efficiency and cost. Torque can be balanced to meet your RPM and working life requirements. Light-weight with low backlash performance (less than 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 provide an result shaft at 90° from the input, and so are obtainable in gear ratios from 1:1 to 40:1. Lightweight but long lasting, with machined light weight aluminum 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 a few minutes of backlash or better. Also called “shaft to bore gearboxes,” these devices provide a single insight shaft that protrudes from opposing sides of the casing; output is a keyed bore. Standard solitary- and double-end shafts are available and supplied with keys and retainer rings. An array of equipment ratios and insight sizes are available to meet your needs.
High efficiency: up to 86% at 1,000 RPM
Low backlash: ≤30 arc minutes or better
Available 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 metal gears, solid aluminium housings, and long term 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 functionality with low backlash.
