class="u-fs-M">*1: Value when horizontal. (Use clean, dry and nonfreezing air) However, as the stroke increases, it will likely be affected by the weight of its moving parts and the pressure will likely increase by approximately 0.003 to 0.005 MPa due to an offset load from the weight of the rod. <br />*2: See p. 339 in the SMC catalog regarding information on lubrication. This product uses turbine oil as an initial lubricant. Lubricant may seep out of the rod or the piping port. <br />*3: Control low speed actuation with differential pressure, speed controllers, etc. (Refer to the recommended circuit example on p. 319 of the SMC catalog for details.) <br />*4: The values are only for reference and are not guaranteed. </p><h3 class="m-h3--wysiwyg">Diagram</h3><div class="m-cols" data-autoheight="group"><div
