SMS DESIGN FEATURES Piston rod is hard chrome plated type 303 stainless Rod extension/wrench flats are long enough to fit standard wrenches. Special heavy duty wiper not only seals out solid contaminants but also effectively prevents liquids and gases from entering the cylinder interior. End caps are type 303 stainless steel Clean crevice free threaded construction assures maximum strength and allows easy wash down Heavy /8 wall type 304 stainless tube is precision honed Brass or aluminum piston is attached with a high strength threaded joint. Reduce noise and fatigue problems such as rod breakage with urethane/nitrile shock pads. Add /4" to the cylinder length for each pad. Pneumatic use only to 80 F. Pneumatic rod seal is a "longlife" nitrile cup. Hydraulic rod seal is pressure energized and extra long wearing for improved sealability. Composite rod bushing has high temperature capability and excellent chemical resistance. Solid lubricant fillers provide excellent wear characteristics for non-lube service. The bearing is inboard of the wiper and seal, away from the environment Optional wick provides teflon lube for non-lube service on O ring piston. Standard piston seal is large cross section O ring. Compounds are carefully selected for maximum cycle life. Optional U cup piston seals with teflon wear strip stretch the limits of service even futher. Reduce friction and operate without lube in the severest applications while extending or eliminating the service interval. If space permits for applications involving side loads or long strokes, select SMS, 2, 3, 5, 7, 8, 9, which have extra long bearings with added space between support points. Strokes longer than the maximum listed in the ordering procedure can be produced but careful consideration must be given to how the cylinder is applied how well is the load supported or guided, is the cylinder used in push or tension, is the cylinder vertical or horizontal, etc. Consult factory on all strokes longer than standard. Stroke increments other than standard can also be made. Special lengths are generally available in a few days and are priced as "non-standard" strokes. TM 36
