With side load impact angles of more than 5° the operating
lifetime of the shock absorber reduces rapidly due to
increased wear of the rod bearings. The optional side load
adapter provides a long lasting solution.
Material: Threaded body and plunger, hardened high tensile
steel

Problem: Rotary motion of the striking surface creates side load,
which develops a bending moment on the piston rod.
This can bend the rod in some cases. In all cases, side
load will reduce seal and bearing life.
Solution: Use side load adapter.
Formula:
Example:
s
á = tan ( ) 2 • tanámax -1 s
2 • Rs Rsmin =
s = .98 (25mm)
Rs = 3.94 (100mm)
á = tan-1( ) .98
2 • 3.94
á = (7.09).
á max = 25. (adapter 250-0560)
.98
R 2 • tan 25 smin =
Rsmin = 1.05 (27mm)
á = angle of impact
á max = maximum angle of impact
