Small Precison Worm Decrease Gearboxes
There are numerous of specifications you will have to consider when coming up with a worm gearbox selection.
First, what is the insight and output torque requirements? Next, examine vendor horsepower/torque charts and select the correct worm equipment reducer.
If how big is the gearbox will probably be an important consideration then check the reducer dimension specs, not all manufacturers make compact units. In fact, working with the proper supplier will help you not only find the right equipment reducer but also prevent some of the most typical mistakes in reducer selection. We provide a free guide to assist you find the appropriate supplier to utilize.
For low and fractional horsepower application we offer two sizes of worm equipment reducer, the SW-1 and the SW-5. Size and torque output are the major variations between these two models. Both feature either a hollow or solid result shaft. Both models are compact and provide users a wide selection 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 task is essential to selecting the correct worm gearbox.
