A sealing lip made of an elastomeric or thermoplastic material that seals dynamically and statically against the shaft. The lip has a sealing edge that is formed by moulding, cutting or grinding. It is normally pressed against the counterface surface of the shaft, with a defined radial load, by a garter spring.

CR Seals from SKF Founded in 1878 as Chicago Rawhide, CR Seals has one of the longest histories in the seal industry. For the last 110+ years, CR Seals has been setting performance and service life standards for industrial and automotive shaft seals.

About CR chlorobutadiene Neoprene rubbers are homopolymers of chloroprene (chlorobutadiene) and were among the earliest synthetic rubbers used to produce seals. CR has good aging characteristics in ozone and weather environments, along with abrasion and flex cracking resistance.

PolyPaks are multi-purpose seals that are precision molded, multi-purpose sealing devices combining an O-Ring type O-Spring with a conventional lip Seal. PolyPaks provide excellent seal from hard vacuum to more than 60,000 Psi.

The actual seal width is approximately 0,4 to 0,8 mm (0.016 to 0.032 in.) wider than the bore depth B. For all-rubber HS and HSS seals, the bore depth tolerance should be ±0,13 mm (0.005 in.) and ±0,10 mm (0.004 in.)

Thanks to our advanced sealing technologies, designs and development processes, CR Seals outperform the competition on the test bench and in the real application. Why risk unplanned downtime and high warranty costs with a sub-par seal?

Some of the most common materials used for oil seals are nitrile, highly saturated nitrile, Viton®, FEP, silicone and polyacrylate. Simriz® oil seals are molded of an elastomer that has the broadest chemical resistance of any elastomeric material.
