Linear Reciprocating (ASTM G133)

The Linear Module reproduces the reciprocating motion typical in many real-world mechanisms. The instrument produces a friction coefficient for both the forward and backward movements of the stroke. This reciprocating technique is very useful for studying the static coefficient of friction over time, as opposed to the kinetic coefficient measured with the Pin-on-Disk wear testing geometry. The software allows change of friction at any specific point along one lap to be plotted versus time.
