This causes shock loading leading topremature cylinder failureor excessivemaintenance. Usingoversized cylinders towithstand this shock loading is not thebest solution since this considerably increases air consumption and costs. The side loading is removed from the shock absorber piston rod leading to considerably longer life. Seepage36 formoredetails. The lever 1 swingswith thepin2 in a slotted hole aroundpivot point 3. The lever is smoothly decelerated at theextremeend of its travel. It is possible touseonly one shock absorber for bothendpositionsby using different pivot points as shown. Tip: Leave approx. 0.06 inches of shock absorber stroke free at eachendof travel. With a little additional work anormal uni- directional shock absorber canbe converted towork in2directionsby using amecha- nism as shown. By using the air bleed adaptor theoperat- ing lifetimeof shock absorbers in aggres- siveenvironments canbe considerably increased. The adaptor protects the shock absorber seals from cutting fluids, cleaning agents, cookingoil, etc. by using a low pressure air bleed. 1 2 3 Free Travel Rs α Stroke s Pivot Point of Lever ShockAbsorber Stroke ShockAbsorber Stroke Seal with Teflon Tapeor Sealant InstallationExamples For: optimumdeceleration higher speeds smaller cylinders reduced air consumption smaller valves andpipework Example: MA3350-Z (cylindermounting) 4 Oneshockabsorber for bothendsof travel 3 Undamped free travelwith dampedendposition 1 ACEShockabsorbers for pneumaticcylinders
