®C SeriesCylinders/RamsForty models to choose from. Capacities range from 5 to 100 tons and strokes up to 16 in. (406 mm).Designed for working pressures up to 10,000 psi (700 bar). Accessories are available to add to these rams’ versatility.Also available with locking collars (C_____CL Series)10Features:•Grooved ram cap (replaceable)•Internal piston rod threads•Aluminum bronze gland nuts (many competitors use lowerstrength bronze)•Urethane or glass filled teflon rod wipers•Tapered gland nut stop area for dead endingCollar threads with thread protector•Solid steel body (not welded like some competitors offer)Chrome plated piston rod (some competitors have unplated•steel)Rod and body made of better material (mediumcarbon/alloy steel)•Hardened steel stroke limiting stop ring•Aluminum Bronze Piston BearingPremium urethane "U" cup seal with seal guideHeavy duty flat wire spring•Simple spring attachmentBase mounting holes (except 75 and 100 ton models)Benefits:•Prevents damage to the end of the piston rod•Keeps load from slidingProvides for attachment of approved accessories on 5 to•25 ton ramsReduces wear on piston rod and provides high strength forfull dead ending•High strength and better wear than 660 bearing bronzeKeeps dirt, water and other contaminants out of the internalbearing and bore surfaces and has high abrasion resistance•Higher burst pressuresUsed to mount ram in a fixture or attachment and whenfully engaged in a mating thread will withstand the fullrated capacity of the ramProtects unused collar thread•Eliminates leakage sourcesBetter wear and corrosion resistance compared with•uncoated steelHigher strength, more uniform than low carbon used byothers•Better wear and higher burst pressuresHigh strength retainer allows full dead ending without damage•High strength and better wear than 660 bearing bronzeProvides high cycle lifeEliminates seal rolling and leakageMore coils and no spring hooks (loops) provide longer life•Saves time in repairSecure mounting10Rev. 7-31-95
