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