The CR03-P is a high-performance double-acting rotary compact seal specifically designed for pivoting and rotating movements in hydraulic systems, swivel drives, and rotary distributors. This precision-engineered seal effectively manages extreme operating pressures up to 40.0 Mpa / 400 Bar (5800 PSI) and peripheral velocities of 0.2 m/s (0.65 ft/s). Featuring an interference fit on the outside diameter and integrated active back-up rings, it provides exceptional stability and significantly reduces the risk of gap extrusion across a wide temperature range of -30℃ to +100℃ (-22℉ to +212℉).
