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
