The rollers move linearly within the channel as they counter-rotate. During the motion each contact surface has the same surface velocity, which results in very low friction. The Rolamite can be used in various ways such as a component in switches, thermostats , valves, pumps, and clutches .
Transport equipment is used to move material from one location to another (e.g., between workplaces, between a loading dock and a storage area, etc.), while positioning equipment is used to manipulate material at a single location. [3] The major subcategories of transport equipment are conveyors, cranes, and industrial trucks.
The rollers crisscross each other at a 90° angle and move between the four semi-flat and parallel rods that surround the rollers. The rollers are between "V" grooved bearing races, one being on the top carriage and the other on the base.
