12.1
Life of Actuator Using Ball Screws
The life of actuator using ball screws is set to 5,000 km (guideline), assuming it is operated with the
maximum loading capacity and maximum acceleration/deceleration.
12.2
Life of Actuator Using Slide-screws
The lead-screw type actuator uses a lead screw and its nut wears over time.
A reference for product life is presented based on the wear amount of the nut.
The positioning precision of this product, such as lost motion, will drop as the wear of the nut progresses.

Horizontal application
10 million back-and-forth operations
Vertical application
5 million back-and-forth operations
12.2.1 Relationship of Cycle Time and Product Life
(1) Horizontal application
The graph below shows the relationship between the cycle time for one back-and-forth operation and the
life of the product in a horizontal application (product life: 10 million back-and-forth operations).
The lines based on 8 hours of operation and 24 hours operations a day, for 240 days a year, are shown.
Use this graph as a reference when determining the product life.
