If rotational torque is applied, the non-rotating guide will be deformed, resulting in a loss of non-rotating accuracy. Also, to screw a bracket or a nut onto the threaded portion at the end of the piston rod, make sure that the piston rod is fully retracted, and place a wrench on the parallel section of the rod that protrudes. To tighten, take precautions to prevent the tightening torque from being applied to the non-rotating guide. 1. Please consult with SMC when the rod seal is to be replaced. A rod seal may allow air leakage depending on the position where it is installed. Therefore, please consult with SMC when a rod seal is to be replaced. 2. Do not replace the non-rotating guide. Since the non-rotating guide is press fitted, the entire cover assembly needs be replaced instead of a single part. Precautions Be sure to read before handling. Refer to front matter 57 for Safety Instructions and pages 3 to 12 for Actuator and Auto Switch Precautions.
