They are availablewithbody diameters from0.59" (15mm) to1.57" (40mm) andwith stroke lengths of up to31.5" (800mm). Unlike standardHydraulicDampers that include free travel up to20%of stroke, thesedependable units haveno free travel and are ideal for applications that require this level of perfor- mance. Double-actingHydraulicDampers are standard. However, a single actingdesign is available. Adjustment is easily achievedby pulling and turning the roduntil thedesired damping speed is achieved. The travel speed is adjustable and remains constant throughout the stroke. The single acting version is con- trollable inonedirectiononly, with free-flow in theoppositedirection. Abuilt-in antilock guard allows adjustment tobemade at any damping ratewithout unit lock up. These reliableunits offer long life-cycleperformance and are available forQUICKDELIVERY. A variety of end fittings are available for easeof operation and installation, and are included.
