The lowest cost and shortest delivery schedules are normally achieved through the application of standard worm and gear sets. In addition to using common shaft center distances, ratios, and bearing mounting parts, designs will include normal bores, flanges, and bolt circles where feasible. Since the utilization of nonstandard hubs is not uncommon to the worm gear 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, steel, brass or plastic-type material materials. Available in several sizes ranging from module 1 to module 5.
