KR4620A+ 740L-00000 THK KR4620A Series Linear Motion Actuators Axial Deep Groove Ball Bearings SS-511 (Stainless Steel) 8mm BN = 7KR4620A+ 740L 00000 THK KR4620A Series Linear Motion Actuators The KR Actuator features a one piece outer rail with two integrated linear motion raceways for each block side. Assembly costs are reduced by incorporating both the drive mechanism (belt or ball screw) and the guide mechanism (LM Guide) into one unit. THK Linear Motion Actuators reduce the number of separately installed motion components, and the utilitarian design of a ball screw drive
