Description
Prevents external contaminants from entering the system. A single-lip wiper (the lip refers to the protruding portion or edge of the seal) cleans the rod as it retracts. A double-lip wiper cleans the rod as it retracts and seals oil to eliminate oil leakage (external leakage). The double-lip wiper is retained with a bearing retainer. These polyurethane wipers are wrapped in metal on the outside for added strength. They are often referred to as encased wipers (metal-encased) or J-style wipers (the metal is typically J-shaped in cross-section).
