  • * The external dimensions for each mounting type and the dimensions of accessories (options) are the same as the standard type double acting single rod model. Refer to the manufacturer's catalog.

Notes

Minimum Stroke for Auto Switch Mounting

  • * The minimum stroke for mounting varies with the auto switch type and cylinder mounting type. In particular, the center trunnion type requires careful attention. (Refer to the catalog for details.)

Precautions for Use

  • *Avoid applying rotational torque to the piston rod. The non-rotating guide may become deformed, compromising the accuracy. Also, when screwing the nut onto the thread of the piston rod end, ensure the piston rod is fully retracted and use a wrench flat on the part protruding from the parallel part of the rod.
    At this time, be careful not to apply tightening torque to the non-rotating guide.

Disassembly/Replacement

  • * Contact the SMC support center when exchanging the rod packing. Air leaks may occur according to the position in which the rod packing is incorporated, so contact the SMC support center when exchanging the rod packing.
    Do not exchange the non-rotating guide. The non-rotating guide is press-fitted, so use a cover assembly when exchanging.

Other

  • * Before using, please refer to the "Safety Precautions," the "Actuator Precautions," and the "Auto Switch Precautions."
  • * Product images are representative models.
  • * Refer to the manufacturer's catalog for information not detailed above.
■ Refer to the table below for details about lead wire / connector specifications.

■ Made-to-order specifications: For details regarding a change to the trunnion bracket mounting location, please see below.
