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.

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 "4-Ballway/4 points-contact" structure to assure high degree of rigidity. Guide rail, slice block and ball screw shaft are accurately ground, making accurate positioning possible.

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.
