Feature

Important notes on selection

(1) Load capacity shown assumes an operation in 0.3G (0.2G for lead 2.5 and vertical oriented), which is the upper limit of acceleration.
(2) Available duty depends on the operating condition (e.g.load mass, acceleration/deceleration). Please refer to page 1-448 for further details.
(3) Horizontal load capacity shown assumes an operation running with an external guide. Detent mechanism may get damaged if a force was applied to the rod, except towards its moving direction.
(4) Encoder type box for model item will be "I" for simple absolute as well.
(5) Safety measures may be required depending on the attachment orientation. Please refer to page 1-379 for further information.

*1 Connect the motor / encoder. Please refer to page 1-293 for the further details about the cable.

*2 The rod moves to the ME upon returning to origin, so please take precaution that it may not interfere with anything during the process.

*3 The direction the width between two flats are facing differs by product.

(Note) The external dimension will be the same for both with or without brake. Minimum stroke for brake equipped specification starts from 70mm, and does not support any intended use of 60mm and below.

(Note) Do not apply any external force on to the rod except towards the direction of its movement. Detent mechanism may get damaged if a force was applied to the rod from its right angle, or towards its rotating direction.
