The STEFA / TRELLEBORG 32x50x10 CB NBR Oil Seal is a high-quality radial shaft seal engineered for industrial rotating equipment where reliable lubricant retention and efficient sealing performance are essential.

The CB profile (equivalent to Trelleborg TRA design) features a spring-loaded primary sealing lip with a fully rubber-covered outer diameter. This construction provides excellent static sealing between the seal and housing while maintaining consistent radial pressure on the shaft surface. The design is especially suitable for clean industrial environments where contamination levels are moderate.

The integrated garter spring continuously maintains sealing force throughout the seal's service life, helping to reduce lubricant leakage and extend equipment reliability. The rubber-covered outer diameter also compensates for minor housing imperfections and thermal expansion differences.

Manufactured from premium NBR (Nitrile Butadiene Rubber), the seal offers excellent resistance to mineral oils, lubricating grease, hydraulic fluids, and petroleum-based lubricants. NBR remains the most commonly used oil seal material for industrial applications because of its excellent balance of oil resistance, flexibility, wear resistance, and cost efficiency.

With dimensions of 32 x 50 x 10 mm, this seal is commonly installed in electric motors, industrial gearboxes, pumps, conveyor systems, agricultural equipment, and general industrial rotating machinery.
