THK Linear Actuators

The KR Actuator features a one-piece outer rail with two integrated linear motion raceways for each block side. A ball screw drive through the center of the block completes this space-saving design. Every actuator in this line offers extremely rigid and highly accurate functions and utilities.

Assembly costs are reduced by incorporating both the drive mechanism (belt or ball screw) and the guide mechanism (LM Guide) into one unit. The compact GL linear actuator reduces the number of separately installed motion components.
