Small Precison Worm Decrease Gearboxes
There are a variety of specifications you will have to consider when coming up with a worm gearbox selection.
First, what’s the insight and output torque requirements? Next, check 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 specs, not all manufacturers make compact units. Actually, working with the right supplier will help you not just find the right gear reducer but also prevent some of the most common mistakes in reducer selection. We offer a free guide to help you find the right supplier to work with.
For low and fractional horsepower application we offer two sizes of worm equipment reducer, the SW-1 and the SW-5. Size and torque output are the major distinctions between these two models. Both feature either a hollow or solid output shaft. Both models are compact and provide 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 unique application or task is essential to selecting the right worm gearbox.

Micro Gearbox Options
Gearboxes are also known as reducers, gear reducers, rate reducers, gear drives, and gearmotors. All conditions can be used more or less interchangeably. Please note that the links for our little gear drives include information on the full range of body sizes for that series or design.
Bevel Box Micro Equipment Drive
Our bevel container miniature equipment drives are app rated for the the best balance of overall performance and cost. Torque can be balanced to meet your RPM and operating life requirements. Light-weight with low backlash efficiency (less than 1°, with choice 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 amounts of thrust in a concise package. They offer an result shaft at 90° from the input, and so are available in equipment ratios from 1:1 to 40:1. Light-weight but long lasting, with machined aluminum housings and hardened alloy steel gears.
High efficiency: up to 88% at 1,000 RPM
