Saint-Gobain Rulon® AR Bearing/Seal PTFE

Rulon® AR is somewhat more flexible than Rulon® LR, hence suitable for seals and bonded coating of slide surfaces. It has many decades of use in automotive shaft seals and fuel metering pump cups. Rulon AR has a practically universal chemical inertness like that of Rulon LR and provides long life and reliability in continuous non-lubricated service. It is capable of operating at PV values up to approximately 10,000 psi-ft/min. Higher PV values are possible for intermittent use applications.Key Attributes:Universal chemical inertnessLong life and reliability in continuous non-lubricated serviceMore flexible than Rulon® LRWorking Temperature Range: -240° to +288°C [-400° to +550°F]
