Small Precison Worm Decrease Gearboxes
There are numerous of specifications you will need to consider when coming up with a worm gearbox selection.
First, what’s the input and output torque requirements? Next, examine vendor horsepower/torque charts and select 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 producers 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 offer a free guide to help 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 distinctions between these two models. Both feature either a hollow or solid result shaft. Both versions are compact and provide users an array 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 task is essential to selecting the correct worm gearbox.
