3. Product Life

This actuator applies a lead screw and the plastic nut gets worn away. As the plastic nut is worn, the accuracy of

the lost motion mainly gets worse. Based on the abrasion of the plastic nut and the degradation in the

performance of the grease on the screw, the product life is determined as it is described below. (It is the value

when an external guide and a free joint are used.)

Horizontal/vertical 10,000,000 cycles
