The CFW 45x76x9 BA NBR Oil Seal is a high-performance radial shaft seal developed for industrial applications requiring dependable lubricant retention and protection against leakage.

The BA Profile is one of the most widely used Freudenberg oil seal designs. It features a steel-reinforced body with a rubber-covered outer diameter and a spring-loaded primary sealing lip. This design provides excellent static sealing between the housing and the seal while maintaining consistent radial pressure against the rotating shaft.

The elastomer-coated outer diameter compensates for minor housing imperfections and thermal expansion differences, improving sealing reliability and installation performance. The garter spring continuously maintains sealing force throughout the operating life of the seal, helping reduce oil leakage and extend equipment life.

Manufactured from premium NBR (Nitrile Butadiene Rubber), the seal provides excellent resistance to lubricating oils, hydraulic fluids, gear oils, and grease. NBR remains one of the most commonly specified materials for industrial oil seals because of its excellent balance of oil resistance, durability, flexibility, and cost efficiency.

With dimensions of 45 x 76 x 9 mm, this seal is commonly used in industrial gearboxes, pumps, electric motors, conveyors, agricultural machinery, and imported European equipment.
