Advantages of NBR B2SL double lip design

Technical sealing performance

Main description

The CORTECO 01032063 100x125x13 NBR B2SL oil seal is a professional double lip shaft seal designed for reliable rotary sealing in demanding industrial, agricultural and mechanical applications. Manufactured from high-quality NBR (nitrile rubber), this simmerring provides excellent resistance to oils, greases and mechanical wear, ensuring long service life and stable sealing performance.

The B2SL design indicates a double lip oil seal with an additional dust lip. The primary sealing lip prevents lubricant leakage, while the secondary lip protects the sealing area from dust, dirt and moisture. Compared to a single lip oil seal, this construction significantly improves sealing efficiency and extends operational durability in harsh working environments.

With dimensions 100x125x13, this shaft seal is commonly used in gearboxes, engines, drive systems and heavy-duty machinery. It is suitable for continuous operation where effective technical sealing and protection of rotating components are critical. The integrated tension spring ensures consistent contact pressure on the shaft, supporting reliable sealing even under variable loads.

This oil seal is compatible with selected CLAAS machinery (OEM reference 02123970), making it a dependable solution for maintenance, service and replacement in agricultural equipment. As a high-quality oil seal for machinery and engines, it helps reduce lubricant loss, protect internal components and minimize downtime.

Manufactured by CORTECO, this NBR oil seal meets strict quality standards expected by professional B2B customers across industrial and agricultural sectors.
