High accuracy, high rigidity ballscrew actuator ideal for high-precision positioning.
KURODA JENATEC ball screw actuators are compact single-axis units consisting of a ball screw and a slide guide. With their slide block set in a U-guide rail, the actuators achieve low-profile design and compact shape, allowing for considerable reduction in necessary space as compared with the usual table-type structure. The SG series deliver excellent accuracy and rigidity, making them especially suitable for precision positioning.

Space-saving
Slide block is set in U-guide rail, making it possible to reduce the size and space considerably as compared with the usual table type structure.
Accuracy
Linear motion unit uses "gothic-arch 4 points-contact" structure to assure high rigidity. Guide rail, slide block and ball screw shaft are precise worked, making accurate positioning possible.
Rigidity
Despite of its compact structure, the rigidity of single axis module has remarkable improved by using a U-guide rail, so that it can be applied even to a structure supported at only one end. In addition, short block, long block and second block are available to enhance permissible moment.
No necessity for adjustment
Guide rail and ball screw are integrated in single axis module, eliminating the need for complicated fine adjustment and reducing the number of working processes to a great extent.
