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.

CR Seals are manufactured to meet the industries toughest challenges with superior performance. You can trust the robust reliability that comes with using CF Seals from SKF, and rest assured you won't have to deal with unplanned downtown or a diminished bottom line.

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 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.)

The most common lip seal material is nitrile (Buna-N). This material functions well at temperatures of minus 40 degrees F up to 275 degrees F. Nitrile lip seals cover most applications in industry from new equipment to replacement seals.

Industrial seals are used to prevent leakage, hold pressure, and deflect contamination at interfaces between components. Industrial seals are used at static and dynamic interfaces. Examples of static interfaces include the entry point of bolts and screws, and the interface between an engine block and cylinder head.

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.
