worm gear components

The lowest cost and shortest delivery schedules are normally achieved through the use of standard worm and gear sets. In addition to using standard shaft center distances, ratios, and bearing mounting parts, designs should include standard bores, flanges, and bolt circles where possible. Since the use of non-standard hubs is not uncommon to the worm gear industry, provides for this by having a flanged rim design available for mounting on any adaptable center.
