A6 Wiper Seal
Descriptions
The A6 wiper serves to prevent ingress of dust, dirt, sand and swarf. This is achieved by its special design which largely prevents scoring, protects the guiding parts and extends the service life of the seals. The wiper requires no tight fit due to its integrated dirt shield which ensures operating reliability even in the case of coaxiality fluctuations of up to 1.5 mm, depending on the rod diameter.
Features
• Outstanding wiper properties for excentricity of the cylinder rod.
• Good wear resistance.
• Smooth running due to optimum adjustment of the functional lips.
• Easy snap assembly without assembly aids.
• High temperature resistance in case of suitable compound selection.
• Product geometry prevents dirt deposits at the front face of the cylinder.
• Installation in closed and undercut housings.
Range of application:
The wiper ring of the A6 product series has been developed for axially operated rods in hydraulic and pneumatic working cylinders, plungers and rod guidances. It delivers enhanced performance in applications where excentricity occurs vis-à-vis the groove, with excentricity of up to 1.5 mm being permissable.
