Introduction


K846 is a standard metal dust wiper. It is used for rod seals. K846 is simple dust seal with sealing system. It is including 2 lips in order to exclude dust and moisture from entering into cylinder and collect passing fluid from rod seal.

K846 is a double-acting wiper manufactured from tough, wear resistant p. Its robust outer wiper lip excludes contaminants from the hydraulic system, and the internal wiper lip collects fluids that bypass the primary rod seal, to give dry rod performance.

 

The K846 profile can be used as a heavy to light duty wiper. When used in high pressure applications in conjunction with the proper KOLBEN rod seals, the K846 compliments the sealing system by providing an additional beveled sealing lip, yielding excellent film-breaking and the driest rod sealing available. These dual acting features also enable it to be used by itself in low pressure applications as both the rod seal and the wiper. Knife-trimmed sealing lips ensure the best possible film breaking.

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.
