1 HYDRO-LINE, SeriesCylindersNFPA InterchangeableROCKFORD,ILMetallic Rod ScrapersA Metallic Rod Scraper providesincreased rod seal life by removingabrasive contamination from therod in severe Rod EndsModifications of standard rod ends or completely special rodend styles are available to meet unique rod end connectionrequirements. (See page 33 for standard rod ends.)Special PortsMetric, BSP, NPTF, SAE, Manifold, Flange and other portingoptions are available to meet specific requirements.

2 (See page 24.)Extra Heavy Chrome Tubes and RodsAdded wear and corrosion resistance are available by specifyingExtra Heavy Chrome (.002 to .003 thick).Not available on A5 Series FeedbackA complete line of precision cylinder position sensing and feedbackdevices are available. These packaged cylinder systems canhandle virtually any application requiring feedback throughoutthe cylinder stroke pneumatic or hydraulic, large or smallbore, long or short strokes, with or without velocity monitoring with resolutions of or better.

3 (See the Hydro-LineSystems Catalog.)PlatingElectroless Nickel, Cadmium and other plating finishes areavailable for corrosive, washdown, pharmaceutical, and Profile Reed & Hall Effect SwitchesHydro-Line Low Profile Reed and Hall Effect switches are availablefor all bore size A5 Series cylinders. These switches are activatedby a magnetic band fitted around the cylinder piston. Signalsfrom these switches are used as input to programmable controllers,sequencers, relays, and in some cases, to drive valve page 30-31 for Available on R5 Series Steel Piston RodsPiston rods in 300 and 400 series, 17-4 PH, and others areavailable for those applications requiring increased Coating and PaintingCylinders can be prepared with a primer coat or epoxy, lacquer,or enamel paint finish coatings to customer.
