Precautions Air Cylinder Single Acting: Spring Return Series CJ1 Bore Size: o2.5, o4 How to Order/Single Acting Polyurethane Soft nylon Piping Caution 1. Do not force to connect piping in such a way that the lateral force could be applied on a cylinder tube. This could cause a cylinder tube to slant and malfunction. Because this could cause a cylinder tube to tilt and malfunction. Mounting Caution 1. Do not use it in such a way that a load could be applied to the piston rod during the retraction. The spring that is built into the cylinder provides only enough force to retract the piston rod. Thus, if a load is applied, the piston rod will not be able to retract to the end of the stroke. 2. Do not install it by directly grasping the cylinder tube, as this could cause a tube to deform and malfunction. +0.5 0 mm Tubing type Metric size Material Polyurethane Soft nylon Size O.D. 4 mm 4 mm Model no.
