The lowest cost and shortest delivery schedules are usually achieved through the use of standard worm and gear sets. Furthermore to using standard shaft middle distances, ratios, and bearing mounting parts, designs should include standard bores, flanges, and bolt circles where likely. Since the use of nonstandard hubs isn’t uncommon to the worm gear industry, Ever-power offers this by having a flanged rim style available for installation on any adaptable centre.
Our metric worm gears come in pairs with worm shafts or worms. They are constructed of stainless steel, metal, brass or plastic-type materials. Available in different sizes ranging from module 1 to module 5.
