The lowest cost and shortest delivery schedules are usually achieved through the utilization of standard worm and gear sets. In addition to using common shaft middle distances, ratios, and bearing mounting parts, designs will include standard bores, flanges, and bolt circles where conceivable. Since the use of nonstandard hubs is not uncommon to the worm equipment industry, Ever-power provides for this by having a flanged rim design and style available for mounting on any adaptable center.
Our metric worm gears can be found in pairs with worm shafts or worms. They are constructed of stainless steel, steel, brass or plastic material materials. Available in various sizes which range from module 1 to module 5.
