Max Spare : W38
Profile : Wiper Seals
Details :
W38 is a double acting wiper seal with two geometrically different wiping lips suitable for medium to heavy duty hydraulic cylinders with small groove dimensions. It comprises of combination of O-ring energiser and outer seal ring made of PTFE added with a filler to increase the resistance of seal ring to wear & tear. The o-ring energizer provides the force necessary to maintain the pressure 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
