Sealing, cushioning options enhance Festo stainless steel cylinders

May 30, 2018 – The latest generation of Festo’s CRDSNU round stainless steel pneumatic cylinders boasts new variants and installation possibilities for extended and contaminant-free operations. Based on the ISO 6432 standard and suitable for operations in harsh environments or where frequent and effective cleaning is a must, CRDSNU now offers options like an extremely long-life dry running seal as well as self-adjusting end-position cushioning, explains the company.

CRDSNU cylinders are used in food and packaging, chemicals and medical technology as well as in resource extraction. Variants are available with threadless front mounting which is designed to reduce the risk of contamination. Festo’s proprietary self-adjusting cushioning PPS does away with the adjusting screw, another place contaminants may lodge, it explains, adding that it is even resistant to aggressive media. Nevertheless, if a replacement dry running seal or hard scraper is needed, the cylinder’s two-part split bearing cap allows a new one to be installed quickly and easily without de-installing the cylinder, helping to reduce system downtime, says Festo. The CRDSNU line includes variants and mounting options suitable for almost every application, including low-temperature and heat-resistant versions and various piston rod setups: through piston rod, extended piston rod thread, or piston rods with female or special thread.
