Precautions during push-operation

When performing high-thrust pushing operations in a high-temperature environment, use the product within the limits shown in the graph.

Adaptive controller

(Note) EC series has their controller built-in themselves. See page 2 769 for details of the built-in controller.

Oversea specification

Important notes on selection

(1) The payload capacity indicated in the "Main specifications" is the maximum value. Please refer to "Load capacity by speed and acceleration table" for further information.
(2) The horizontal payload assumes that a guide is used in combination to prevent radial load and moment load from being applied to the rod. If you decide not to install a guide, please refer to "Front bracket tip load and running life".
(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.

Dimension drawing

ST： Stroke

M.E.： Mechanical end

S.E.： Stroke end

(Note) The rod moves to the M.E. upon returning to origin, so please take precaution that it may not interfere with anything while the returning process is running.

(Note) Secure the cable so that the base of the cable does not move.

　Cables can be separated and replaced. (Connector connection inside cable box)

　The standard exit direction for the actuator cable is from the rear side.

　The cable exit direction (optional) can be changed by changing the direction of the cable box.
