The cushioning ability depends to a large extent on the pneumatic circuit (e. g. counter pressure, pre-exhaust). The values given in the diagram were tested with an operation pressure of 87 psi (6 bar) using a 5/2 control valve. When installed horizontally, depending upon the speed, dynamic energy can be absorbed by the cylinder. Whenever the values given in the diagram are exceeded, the transported mass must be cushioned by additional shock absorbers. These have to be located at the center of gravity of the mass. inches (mm) 19.7' (6000) 16.4' (5000) 13' (4000) 9.8' (3000) 6.5' (2000) 3.2' (1000) 0 2 0.04" (1) 0.004" (0.1) 0.02" (0.4) ft.

(200 N) and a deflection about 0.04 (1 mm). Maximum distance between supports = 6' (1830 mm) (see diagrams). Therefore an additional support is required. 72" (1830) inches (mm) f1= 0.04" (1 mm) 2248 (10000) 1124 (5000) 224 (1000) 112 (500) 22.5 (100) 2.25 (10) 0.22 (1) 39" (1000) 0 6.6' (2000) 9.8' (3000) 13' (4000) 16.4' (5000) 19.6' (6000) F ibf (N) ø80 ø63 ø50 ø40 ø32 ø25 ø20 ø16 Deflection due to external forces Support length Example: Cylinder Ø 40 mm. external force 40 lbf (180 N), distance between supports 10' (3000 mm) Required: total deflection 1.
