The lowest cost and shortest delivery schedules are usually achieved through the usage of standard worm and gear sets. Furthermore to using regular shaft middle distances, ratios, and bearing installation parts, designs will include regular bores, flanges, and bolt circles where likely. Since the use of nonstandard hubs is not uncommon to the worm equipment industry, Ever-power offers this by having a flanged rim style available for mounting on any adaptable center.
Our metric worm gears come in pairs with worm shafts or worms. They are made of stainless steel, metal, brass or plastic-type material materials. Available in different sizes which range from module 1 to module 5.
Ever-power manufactures worm equipment sets, which are made up of a worm and worm wheel, for use in a number of industries including aerospace and military instrumentation, medical, dental care, oil and gas exploration, robotics, optical and commercial handles.
