Small Precison Worm Decrease Gearboxes
There are a variety of specifications you will have to consider when making a worm gearbox selection.
First, what is the insight and output torque requirements? Next, verify 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 specs, not all manufacturers make compact units. Actually, working with the proper supplier can help you not only find the right gear reducer but also prevent some of the most common errors in reducer selection. We offer a free guide to assist you find the right supplier to utilize.
For low and fractional horsepower app you can expect two sizes of worm gear reducer, the SW-1 and the SW-5. Size and torque output will be the major differences between these two models. Both feature either a hollow or solid output shaft. Both models 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 particular application or project is essential to selecting the right worm gearbox.

Micro Gearbox Options
Gearboxes are also known as reducers, gear reducers, speed reducers, gear drives, and gearmotors. All conditions can be used pretty much interchangeably. Please note that the links for our little gear drives include details on the full range of body sizes for that series or style.
Bevel Box Micro Equipment Drive
Our bevel box miniature gear drives are application rated for the optimum balance of functionality and cost. Torque can be balanced to meet your RPM and working life requirements. Lightweight with low backlash efficiency (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 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 result shaft at 90° from the input, and 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: as low as ≤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 minutes of backlash or better. Also known as “shaft to bore gearboxes,” these devices provide a single input shaft that protrudes from opposite sides of the housing; output is usually a keyed bore. Standard single- and double-end shafts can be found and supplied with keys and small worm gearbox retainer bands. An array of gear 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
