The CR02-P is a high-performance self-retaining radial shaft seal engineered for drive systems, pumps, and industrial gearboxes where protection against external contaminants is essential. This rotary shaft seal effectively manages operating pressures up to 0.5 Mpa / 5 Bar (72.5 PSI) and peripheral velocities of 0.5 m/s (1.6 ft/s). Designed in compliance with DIN 3760 design AS, it features an integrated clamping ring as an anti-twist device, a garter spring-loaded dynamic lip, and a dedicated dust lip to protect the primary sealing interface from dust and dirt across temperatures from -30℃ to +80℃ (-22℉ to +176℉).

• BESPOKE SEALING SOLUTIONS: Tailor-made profiles optimized for specific non-standard housing requirements, ensuring a perfect fit without mold costs.
• HIGH-PRECISION LATHE-CUT: Advanced CNC machining provides exact lip geometry and enhanced surface finish for superior static and dynamic tightness.
• HEAVY-DUTY INDUSTRIAL CAPACITY: Specialized in manufacturing high-performance large seals up to 3000mm, designed for extreme heavy machinery and oversized bore hydraulics.
• INTEGRATED DUST EXCLUSION: Secondary dust lip keeps external contaminants away from the primary sealing interface, significantly extending the service life of the shaft and seal.
• ANTI-TWIST STABILITY: Self-retaining design with an integrated clamping ring prevents seal rotation in the bore, even at increased surface roughness and thermal expansion.
The CR02-P series offers a superior sealing solution for apparatus engineering, combining an advanced FKM / Viton compound with a dual-lip design for maximum environmental exclusion. Its self-retaining structure includes a specialized clamping ring that acts as an anti-twist device, ensuring the seal remains stationary in the housing bore. With a high recovery rate and flexible lip geometry, the CR02-P excels at compensating for shaft-to-bore misalignment and run-out. This model provides high sealing efficiency and low breakaway torque, making it a reliable, high-performance alternative for rotating shafts in split housings or aggressive industrial environments.
