The CR04-A is a high-performance double-acting rotary compact seal specifically engineered for static and dynamic applications with pivoting movements in hydraulic systems and swivel drives. This specialized compact seal effectively manages operating pressures up to 16.0 Mpa / 160 Bar (2320 PSI) and peripheral velocities of 0.2 m/s (0.65 ft/s). Featuring an interference fit on the outside diameter for inside dynamic sealing surfaces, its space-saving design allows it to snap into simple grooves, providing an excellent sealing effect across a wide temperature range of -30℃ to +100℃ (-22℉ to +212℉).
