A new linear motion guide actuator from THK features a driving element that uses right/left threads and enables symmetrical movements with a single motor. Formerly available only as a custom system, THK responded to the high demand for a right/left actuator by adding the Type KR-RL to its portfolio.

The modular linear actuator design makes it possible to grip objects and perform open-and-close operations with a single motor by using a right/left screw simultaneously capable of both right and left drive for the ball Source: THKscrew axis. The principle target market includes the electronics and automotive component industries, where demand for process automation is expected. The product is optimal for applications such as the parts that move tooling in fully automated wire strippers, electric robot grippers, screw tightening machines and dispensers.

The Model KR-RL is available in nine sizes ranging from 15 mm to 65 mm. Fewer individual pieces than component products translates into reduced assembly time for the drive element. The advantage of a single shaft capable of simultaneous right and left drive is that this single-axis modular product can be used to replace more complex component products relying on multiple axes, which helps reduce device size.
