N O R G R E N Series A, EA, J & EJ Optional Features & Custom Cylinders All Dimensions in Inches Adjustable Stroke Provides variable reduction of the retract stroke and serves as a positive stop for the cylinder piston. Consists of a threaded stud located in the cap end of the cylinder. Milled wrench flats on the end of the adjustment stud allow for simple yet precise positioning to accommodate varying retract stroke requirements. TO ORDER: Enter option code A(_) . Specify adjustable stroke length. Adjustable Stroke with Piston Provides variable reduction of the retract stroke and serves as a positive stop for the cylinder piston. Consists of an adjustable stop piston at- tached to a threaded stud located in the cap end of the cylinder. Milled wrench flats on the end of the adjustment stud allow for simple yet precise positioning of the stop piston to accommodate varying retract stroke requirements. TO ORDER: Enter code AA(_) . Specify adjustable stroke length. Additional Female Thread Depth Piston rod thread depth can be ordered over standard. TO ORDER: Enter option code TF(_) and specify additional "A" depth. Additional Male Thread Length Piston rod thread extension can be ordered over standard. TO ORDER: Enter option code TX(_) and specify additional "A" length. Single Acting Spring Extend Available on Cap End of Cylinder for 1-1/2", 2", and 2-1/2" bore sizes, 12" maximum stroke. NOTE: Standard spring extend cylin der has 12 lbs. force pre-load, 30 lbs. force compressed. For other spring forces, bore sizes or longer strokes, consult John Henry Foster Co. TO ORDER: Enter option code SC . Single Acting Spring Retract Available on Rod End of Cylinder for 1-1/2", 2", and 2-1/2" bore sizes. 12" maximum stroke. NOTE: Standard spring retract cylinder has 12 lbs. force pre-load, 30 lbs. force compressed. For other spring forces, bore sizes or longer strokes, consult John Henry Foster Co. TO ORDER: Enter option code SR . Piston Rod Stud Reduces the chance for piston rod failure. The rod stud can be installed with different thread locker. TO ORDER, enter: Option code BL - removable adhesive sealant. Option code RS - high strength thread locker adhesive. NOTE: Type 2 studded rod shown. Cushion Adjust Screw Optional Locations Option code N(_ _) Specify optional location. Example: N(4 2) cushion location 4 Head end, standard position 2 Cap end. When using option code N , head and cap locations must be specified 1, 2, 3, or 4. Pinned Piston to Rod Norgren will supply a full size piston rod to piston joint, in addition to pinning the piston to the rod, for severe applications. If under normal operating conditions, the pinned piston and rod become detached, Norgren will replace the piston and rod assembly free of charge. TO ORDER: Enter option code PN . Magnetic Piston (No Wear Ring) When position sensing of the cylinder rod is required, a "magnetic piston" must be specified. A magnetic band is placed at the center of the piston which creates a magnetic field to actuate Norgren's reed, solid state or hall effect switch. NOTE: We cannot guarantee the operation of other manufacturers' switches. TO ORDER: Enter option code PS . Metallic Rod Scraper Aggressively scrapes the exposed portion of the piston rod free of weld spatter, paint spray, abrasive powders or many other foreign materials that could damage the rod seal. TO ORDER: Enter option code MS . Piston Rod Seal O-Ring Loaded (Series J & EJ) Pre-loaded lip seal has a very low leakage at low pressure. Excellent for low pressure hydraulic applications. TO ORDER, enter: Option code H - Rod seal only. Option code PP - Rod and piston seals.
