Small Precison Worm Reduction Gearboxes
There are numerous of small worm gearbox specifications you will need to consider when coming up with a worm gearbox selection.
First, what is the insight and output torque requirements? Next, check vendor horsepower/torque charts and pick the correct worm gear reducer.
If the size of the gearbox will probably be an important consideration after that check the reducer dimension specs, not all producers make compact units. Actually, 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 provide a free guide to assist you find the appropriate supplier to work with.
For low and fractional horsepower program we offer two sizes of worm gear reducer, the SW-1 and the SW-5. Size and torque output will be the major distinctions between these two models. Both feature the hollow or solid result shaft. Both models 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 particular application or project is vital to selecting the correct worm gearbox.
