Small Precison Worm Reduction Gearboxes
There are a variety of specifications you will have to consider when making a worm gearbox selection.
First, what is the input and output torque requirements? Next, examine vendor horsepower/torque charts and select 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. In fact, working with the right supplier will help you not merely 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 appropriate supplier to work with.
For low and fractional horsepower software we offer two sizes of worm equipment reducer, the SW-1 and the SW-5. Size and torque output will be the major distinctions between both of these models. Both feature the hollow or solid output shaft. Both models 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 specs of your particular application or task is vital to selecting the right worm gearbox.

Using miniature gears, Ever-Power has designed and built exclusive, high precision mini gearboxes that cannot be found somewhere else. Our miniature gearboxes are available in many configurations, including worm and wheel, cross axis helical, bevel, inline spur, and more. We can also provide customized micro gearboxes that were created and created to meet your specific specifications.
E mail us for the mini gearbox the application requires, or request a quote upon a custom micro gearbox.
Micro Gearbox Options
Gearboxes are also known as reducers, gear reducers, velocity reducers, gear drives, and gearmotors. All conditions can be used pretty much interchangeably. Please note that the links for our small gear drives include info on the full selection of framework sizes for that series or style.
Bevel Box Micro Gear Drive
Our bevel container miniature gear drives are program rated for the the best balance of performance and cost. Torque could be balanced to meet up your RPM and working life requirements. Light-weight with low backlash performance (less than 1°, with choice of 1/2”).
Result torque: up to 7 oz.-inches
Low backlash: ≈1°, option of 1/2”
