Specifications subject to change without notice or incurring obligation 3 precision guiding and long, trouble free life. A rubber disk is included at the end of each guide pin to take up end play and firmly seat the pins in the precision guide pin holes. An information label is applied to each cylinder to warn against damage. Use when any attachment to the piston rod must not rotate. 5-9-13 Option Specifications Adjustable extend stroke Option -AS For strokes through 6" Full stroke adjustment is standard. Note! To maintain operator safety features of this option, it is NOT available with mounting styles: WR and WFR. Use caution when mounting to avoid creating pinch points.

Operating Pressure Square Head Series only in Single Rod and optional Double Rod (-DR) Two guide pins incorporated inside the cylinder pass through the piston head.These guide pins prevent rotation of the rod with a tolerance of ± 1°. The guide pins, being incorporated inside, are protected from the environment, physical damage, and are lubricated by the system lubrication, and require NO additional space, leaving the rod end area free for attachments and tooling as required by your application. The guide pins are precision ground tool steel and run in SAE 660 bearing bronze bushings and Polyurethane O'r ings. These features provide Guide Pin, Ground Tool Steel Rubber Disk Bushing, SAE 660 Bearing Bronze O'Ring, Polyurethane Wrench flat random rotation Finish Plating; Pro-Coat™ , Electroless Nickel, Heads & Tube Option -N Pro-Coat™ , Electroless Nickel Plating is a hard, smooth, corrosion and wear resistant coating. It will often suffice for applications where stainless steel is specified. Its lasting luster provides high eye appeal. The coating is a high nickel, low phosphorous alloy depositedby chemical reduction without electric current that is "mil-for-mil" more corrosion resistant than electroplated nickel. The surface is virtually pore free. The thickness of the nickel deposit is constant over the entire surface. Blind holes, threads, small diameter holes and internal surfaces all receive the same amount of plating. It has natural lubricity and a high resistance to abrasion. As shipped hardness of the coating is approximately 49 Rockwell C. Heat treating can increase hardness to approximately 60 Rockwell C. For specific applications, consult engineering. The cylinder heads and tube, inside and outside, are plated. Tie rods and nuts are standard stainless steel. Rod bushing is standard hard anodized aluminum and Duralon ® . 3.8 WARNING THIS CYLINDER HAS A NONROTATING ROD. TO PREVENT INTERNAL DAMAGE HOLD ROD BY WRENCH FLATS WHEN INSTALLING OR REMOVING ATTACHMENTS.
