Pneumatic cylinders are used for linear work. The key characteristics are fast motion speed and cycle sequences, plus good dynamic performance. The requirements for the sealing systems used are as diverse as the application areas for pneumatic cylinders: from assembly lines in clean and temperature-controlled factory halls to crustbreaker cylinders in aluminum production.
In this webinar, learn how Parker Prädifa's modular seal-wiper kit enables the same pneumatic cylinders to be used for a wide variety of applications.
Due to the extensive variety of sealing materials available, temperature ranges from -200 to +260 °C can be covered as well as extreme requirements in terms of media resistance and cleanliness, dry-running properties, and stick-slip-free operation.
Modified wiper geometries are available to provide protection against ambient influences. They prevent ingress of liquids, viscous media, and deposits on the piston rod into the cylinder.
