This causes shock loading leading to premature cylinder failure or excessive maintenance. Using oversized cylinders to withstand this shock loading is not the best 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. Wherever possible mount shock absorber so that impacting face is perpendicular to shock absorber axis half way through stroke. See pages 44 and 45 for more details. For: • optimum deceleration • higher speeds • smaller cylinders • reduced air consumption • smaller valves and pipework Example: MA 3350 M-Z -Z = cylinder mounting The lever 1 swings with the pin 2 in a slotted hole around pivot point 3. The lever is smoothly decelerated at the extreme end of its travel. It is possible to use only one shock absorber for both end positions by using different pivot points as shown. Tip: Leave approx.0.06 in (1.5 mm) of shock absorber stroke free at each end of travel. With a little additional work a normal unidirectional shock absorber can be converted to work in 2 directions by using a mechanism as shown. s = stroke Free travel 2 1 3 By using this air bleed collar the operating lifetime of shock absorbers in aggressive environments can be considerably increased. The adapter protects the shock absorber seals from cutting fluids, cleaning agents, cooking oils etc. by using a low pressure air bleed. Available for VC and VCL feed controls and select shock absorbers. Shock absorber stroke Shock absorber stroke Pivot point of lever 1. Ace Shock Absorbers for Pneumatic Cylinders 2.
