Small Precison Worm Decrease 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 equipment reducer.
If how big is the gearbox is going to be an important consideration after that check the reducer dimension specifications, not all manufacturers make compact units. In fact, working with the right supplier can help you not only 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 work with.
For low and fractional horsepower software you can expect two sizes of worm gear reducer, the SW-1 and the SW-5. Size and torque output will be 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 specs of your particular application or project is essential to selecting the right worm gearbox.

Using miniature gears, Ever-Power offers designed and built exclusive, high precision mini gearboxes that can’t be found anywhere else. Our miniature gearboxes are available in numerous configurations, which includes worm and wheel, cross axis helical, bevel, inline spur, and more. We are able to also provide customized micro gearboxes that are designed and built to meet your unique specifications.
E mail us for the mini gearbox your application requires, or ask for a quote upon a custom micro gearbox.
Micro Gearbox Options
Gearboxes are also known as reducers, gear reducers, quickness reducers, equipment drives, and gearmotors. All conditions can be used pretty much interchangeably. Please be aware that the links for our little gear drives include info on the full range of framework sizes for that series or style.
Bevel Box Micro Gear Drive
Our bevel box miniature equipment drives are program rated for the the best possible balance of efficiency and cost. Torque can be balanced to meet your RPM and working life requirements. Light-weight with low backlash efficiency (as little as 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 amounts of thrust in a concise package. They offer an result shaft at 90° from the input, and are available in equipment ratios from 1:1 to 40:1. Lightweight but durable, with machined light weight aluminum housings and hardened alloy steel gears.
High efficiency: up to 88% at 1,000 RPM
Low backlash: only ≤30 arc minutes
Rated for input speeds up 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 called “shaft to bore gearboxes,” the unit provide a single insight shaft that protrudes from reverse sides of the casing; output is certainly a keyed bore. Standard one- and double-end shafts are available and supplied with keys and retainer rings. An array of gear ratios and insight sizes are offered to meet your needs.
High efficiency: up to 86% at 1,000 RPM
Low backlash: ≤30 arc minutes or better
Available in ratios from 5:1 to 120:1
Rated for input speeds up to 3,000 RPM
Miniature 4 Shaft Worm Gearbox
Every miniature 4-shaft worm gearbox from Ever-Power features precision-machined hardened metal gears, solid aluminium housings, and long term lubrication. They provide two input shafts on opposing sides of the frame, with two output shafts perpendicular to the input shafts. Our mini 4 shaft worm gear drives deliver high performance performance with low backlash.
