The cheapest cost and shortest delivery schedules are normally achieved through the utilization of standard worm and gear sets. Furthermore to using normal shaft center distances, ratios, and bearing installation parts, designs will include standard bores, flanges, and bolt circles where possible. Since the use of nonstandard hubs isn’t uncommon to the worm gear industry, Ever-power provides for this by having a flanged rim design and style available for mounting on any adaptable middle.
Our metric worm gears can be found in pairs with worm shafts or worms. They are constructed of stainless steel, steel, brass or plastic-type materials. Available in different sizes which range from module 1 to module 5.
