Small Precison Worm Decrease Gearboxes
There are numerous of specifications you will need to consider when making a worm gearbox selection.
First, what’s the insight and small worm gearbox 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 producers 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 typical mistakes in reducer selection. We offer a free guide to help you find the right supplier to utilize.
For low and fractional horsepower application we offer 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 result 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 called reducers, gear reducers, speed reducers, equipment drives, and gearmotors. All conditions can be used pretty much interchangeably. Please note that the links for our little gear drives include info on the full selection of frame sizes for that series or style.
Bevel Box Micro Gear Drive
Our bevel box miniature equipment drives are app rated for the ideal balance of 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 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 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. Lightweight but long lasting, with machined light weight aluminum housings and hardened alloy metal 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 mins of backlash or better. Also known as “shaft to bore gearboxes,” these devices provide a single input shaft that protrudes from opposing sides of the housing; output can be a keyed bore. Standard solitary- and double-end shafts are available and given keys and 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
