OPTIONS: SERIES CRS COMPACT CYLINDERS SHOCK PADS ON EXTENSION AND RETRACTION Shock pads eliminate metal-to-metal contact and minimize piston impact. Shock pads are recommended for applications where the piston travels the full stroke length and contacts the head and/or cap (with no attached loads). The use of shock pads reduces noise and provides maximum cylinder life in these applications. SHOCK PAD ON EXTENSION EXTENDED LENGTH WRENCH FLATS B The design of a compact cylinder requires the length to be as short as possible. The standard wrench flat length is .125" [3 mm]. The option -F11...

OPTIONS: SERIES CRS COMPACT CYLINDERS MAGNET FOR PHD SERIES 6790 & JC1 SWITCHES This option equips the cylinder with a magnetic band on the piston for use with PHD Series 6790 and JC1 Switches. These switches mount easily into the integral slots in the body. PHD recommends the use of stainless steel or de-magnetized fasteners on units with this option. NOTE: Option -M adds 1/4" [6.38 mm] to the overall length of the cylinder of a plain unit. SERIES 6790 & JC1 SWITCHES PART NO.
