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.
