Max Spare : W39
Profile : Wiper Seals
Details :
W39 is a double-acting, twin o-ring energized, rod wiper seal designed to include two different unique wiping geometries. The two lips combine to scrape debris from the rod and contain residual oil on rod extension, as well as allowing oil to pump back into the cylinder. The o-ring energizers provide the force necessary to maintain the engagement of the wiping lips against the sliding surface and allow the wiper to adjust for deflection. Generally, Bronze is used as filler. But, Glass/Graphite filled PTFE can also be made. The Bronze filled PTFE Iiner seal ring when in contact with the piston rod ensures a stick slip free movement & reduces friction to a minimum.
