Important notes on selection

(1) Maximum speed drops when the stroke length increase, preventing it from reaching the critical revolution value of the ball screws. Use the "Stroke and Max.speed" to check the maximum speed at the stroke you desire.
(2) The value shown for load capacity in "Main specification" refers to the maximum value. Please refer to "Load capacity by speed and acceleration table" for further information.
(3) When performing push operation, please refer to the "Correlation diagram of push force and current limit value". Pressing force shown are their standard value. Refer page 1- 315 for important points to be taken note of.
(4) The duty ratio must be limited according to the ambient temperature of use. Refer to page 1-326 for further details.
(5) Requires extra care required depending on the mounting posture. Refer to page 1-307 for further details.
(6) The approximate overhang load length is 400mm or less in Ma, Mb and Mc directions. Please refer to page 2-109 for the overhang load length.
(7) The center of gravity of the attached object should be less than 1/2 of the overhang distance. Even if the overhang distance and load moment are within the allowable values, if abnormal vibration or noise occurs during operation, loosen the operating conditions before use.
(8) When connecting the RCON-EC connection specification (ACR) to the EC connection unit (RCON-EC-4), the number of connections that can be made is limited. Refer to page 2-798 for further details.

ST： Stroke

M.E.： Mechanical end

S.E.： Stroke end

(Note) Please be careful while returning to the home position, for there is a chance of collision while having the slider returning to the M.E. position.

(Note) Please pay attention to the length of the mounting bolt. When using the mounting screws on the back of the base, if the bolts are too long, they may interfere with internal parts and cause abnormal sliding or damage to parts.

(Note) When fixing the actuator using the through hole in the base, the side cover and stainless steel sheet must be removed first.
