Worms and worm gears are used to power right angle, nonintersecting shafts. In normal applications the worm gear is driven by the worm. The most popular use of worms and worm gears is in applications where high ratio speed reduction is desired in a relatively limited space. They are also used in applications where high resistance to the worm gear shaft reversing and driving back through the worm is desired.

The McGill® CAMROL® full complement needle bearings feature black oxide treated bearing steel. They are available in two basic mounting styles for use in mechanical automation or linear motion applications. Our basic features each contribute to superior performance. The LUBRIDISC® seal option helps prevent metal to metal contact within the bearing. It also provides a barrier for containment entry and blowout protection when relubricating. These bearings are available with several dimensional choices. The seal options and combinations provide a specific solution for each application. Within the following section you can learn more about these features and how they can be applied to your application.
