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.

The shaft seal is placed around the rotating shaft, at which point it seals the oil- or lubricant-filled passage. Even if the oil or lubricant is pressurized, it shouldn't leak. The shaft seal's lip will wrap around the rotating shaft.

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.

Different Types of Lip Seals You can find lip seals with a single lip, two lips or even three lips. Lip seals are also available in spring-loaded and non-spring-loaded designs. Spring-loaded lip seals feature an integrated 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.

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.)

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.
