Pressure of operation: static to 20Mpa ( 200 bar) without back-up ring to 40Mpa ( 400 bar) with back-up ring to 200Mpa (2000 bar) with special back-up ring : dynamic off 5Mpa ( 50 bar) with back ring Speed : dynamic 0,5 m/s max. rotary 1,0 m/s max. Temperature : depending of material -50° C bis +240° C Special Features: X-ring as a further development on the O- ring has a square cross section and is pro- vided with sealing lips on the corners. The X-ring sealing effect result is through the 4 sealing lips and not due to deform of the total cross section. The wide range of dif- ferent quality of materials make it possible to seal different gas and fluids. No twisting during mounting and operation Burr-free sealing lips Cost convenient groove geometry Economic constructions Double acting High temperature and pressure range Small space if required Extensive series of sizes XR X-ring Mainly types of X-ring material / Tolerances Surface finish Machining tolerance for static and dynamic application Methodes of Mounting Groove sizes Standard sizes Groove sizes-dynamic external sealing Groove sizes-dynamic internal sealing 254 Content
