Small Precison Worm Reduction Gearboxes
There are numerous of specifications you will have to consider when making a worm gearbox selection.
First, what’s the input and output torque requirements? Next, verify vendor horsepower/torque charts and pick the correct worm gear reducer.
If the size of the gearbox is going to be an important consideration after that check the reducer dimension specifications, not all manufacturers make compact units. Actually, working with the right supplier will help you not just find the right equipment reducer but also prevent some of the most common mistakes in reducer selection. We provide a free guide to assist you find the appropriate supplier to work with.
For low and fractional horsepower app we offer two sizes of worm equipment reducer, the SW-1 and the SW-5. Size and torque output are the major variations between both of these models. Both feature either a hollow or solid result shaft. Both models are compact and offer users a wide variety 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 correct worm gearbox.

Micro Gearbox Options
Gearboxes are also known as reducers, gear reducers, velocity reducers, equipment 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 selection of frame sizes for that series or style.
Bevel Box Micro Equipment Drive
Our bevel container miniature equipment drives are application rated for the ideal balance of performance and price. Torque can be balanced to meet your RPM and working life requirements. Lightweight 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”
Rated for input boosts 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 levels 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. Lightweight but durable, with machined aluminium housings and hardened alloy metal gears.
High efficiency: up to 88% at 1,000 RPM
Low backlash: only ≤30 arc minutes
