Small Precison Worm Reduction Gearboxes
There are a variety of specifications you will need to consider when coming up with a worm gearbox selection.
First, what is the insight and output torque requirements? Next, check vendor horsepower/torque charts and pick the correct worm gear reducer.
If the size of the gearbox is going to be an important consideration then check the reducer dimension specs, not all manufacturers make compact units. In fact, working with the right supplier will help you not just find the right gear reducer but also avoid some of the most typical mistakes in reducer selection. We provide a free guide to help 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 are the major differences between both of these models. Both feature either a hollow or solid output shaft. Both versions 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 unique application or task is vital to selecting the right worm gearbox.

Micro Gearbox Options
Gearboxes are also known as reducers, gear reducers, acceleration reducers, gear drives, and gearmotors. All conditions can be used pretty much interchangeably. Please be aware 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 Gear Drive
Our bevel box miniature gear drives are program rated for the maximum balance of overall performance and cost. Torque can be balanced to meet up your RPM and working life requirements. Lightweight with low backlash performance (less than 1°, with option 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 provide an output shaft at 90° from the input, and are available in gear ratios from 1:1 to 40:1. Light-weight but long lasting, with machined light weight aluminum housings and hardened alloy steel gears.
