How It Works: The Rolling Ring Linear Drive
A rolling ring linear drive converts the rotary motion of a shaft into smooth, reciprocating linear motion, using a sophisticated arrangement of specially engineered rolling rings, making it ideal for a wide variety of industrial applications, from wire winding to precision positioning. Unlike a traditional lead screw, the rolling ring drive uses rollers inside a drive head that press against a smooth, rotating shaft at a set angle. As the shaft rotates, the angled contact and the compression generated against the inner races of these bearings causes them to roll along the shaft’s length, allowing the drive head to travel linearly along the shaft. By changing the angle of the rings, the user can reverse the direction of travel or change the speed of linear motion.
