General
The wiper A7R is designed to reliably prevent the ingress of dirt, dust, grains of sand and metal shavings from dynamic rod guides in difficult environments. Its shape and the appropriate material ensure that stubborn deposits can be safely wiped off. Pressurisation in the back of the scraper should be prevented with this single-sided scraper element.

Installation instructions
The wiper A7R does not require any special screw rings or retaining plates to fit. It can be easily snapped into closed grooves, which are simple to produce. An oversize on the outer diameter ensures the necessary tight fit.
Miscellaneous
To prevent damage, the wipers must not be pulled over sharp edges and corners. For special applications (high temperature, speed, specific pressure load or the use of special media), please contact our application engineering department.
Area of application
For translational movement of piston rods, working and actuating cylinders
