The wear-resistant Ultrathan® AG wiper seal / ring serves to prevent ingress of dust, dirt, sand and swarf at the rod eyes of a hydraulic cylinder. This reduces the risk of “seizure” on the swivel bolt due to external contamination.The good wiping effect is achieved by the special design of the wiper lip.
In addition, the wiper lip opens up during lubrication and allows excess grease to escape. The proven P5008 polyurethane compound stands for abrasion resistance, minor permanent deformation and robustness against external mechanical impact. The wiper is securely held in place in the axially open groove via press-fit of the metal jacket vis-à-vis the inner groove diameter. As the wiper lip is flush with the rod eye it is largely protected against external mechanical damage.
• Robust seal profile for harshest operating conditions.
• Extreme wear resistance.
• Suitable for fully automatic installation.
• Simple fabrication of the housing.
Range of application:
Hydraulic cylinders and valve tappets
