Rotary shaft and wheel hub oil seal for industrial applications

NBR COMBI sealing solution with high durability

Reliable rotary sealing for machinery and transmissions

Main description

The CORTECO 12001913 NBR COMBI 105x125x16 oil seal is a high-quality rotary shaft seal designed for demanding industrial applications where reliable sealing, resistance to lubricants, and long service life are required. This simmerring is commonly used as a shaft oil seal or wheel hub seal in transmission systems and heavy-duty machinery.

Manufactured from NBR (nitrile butadiene rubber), the seal offers excellent resistance to oils and greases, making it suitable for continuous operation in gearboxes, drive systems, and industrial power transmission units. NBR material is widely used in technical sealing due to its flexibility, wear resistance, and stable performance under standard industrial temperatures and operating conditions.

The COMBI design integrates the oil sealing function with additional protection against external contamination, improving overall sealing efficiency and contributing to high durability. This configuration supports long-term rotary sealing by reducing the ingress of dust and debris, which helps protect shafts, bearings, and internal components from premature wear.

With precise dimensions of 105x125x16 mm, the oil seal ensures accurate fit in both shaft and housing, which is critical for correct installation and reliable operation. The product is applied in industrial transmissions and machinery used by manufacturers such as GRAZIANO TRASMISSIONI and NEW HOLLAND, corresponding to reference numbers 3472100353 and 5136004.

The CORTECO 12001913 oil seal is frequently selected by maintenance departments and OEM users as a dependable technical sealing solution for industrial machines, gear units, and rotating assemblies where performance and reliability are essential.
