AN-Style Rod Wipers

RW-XXX

AN-style rod wipers are designed for light duty applications where WD-style wipers are not required.  Wiper seals maintain sealing contact to the piston rod when the equipment is stationary (static, no reciprocating motion of rod) and in use (dynamic, reciprocating rod), whereas the tolerance for the rod diameter d is determined by the rod seal. Without a wiper seal, the retracting piston rod could transport contaminants into the cylinder.
