Rotary Shaft Seal CORTECO 12011063 NBR BA Oil Seal

Rotary Shaft Seal for Front Axle and Wheel Hub

Single-Lip Oil Seal for Agricultural Machinery

Main Product Description

The CORTECO 12011063 NBR BA 105x140x12 oil seal is a high-quality rotary shaft seal designed for reliable shaft sealing in agricultural and industrial machinery. This seal is commonly used in front axle and wheel hub assemblies, including applications in NEW HOLLAND machines, where durable and stable technical sealing is essential.

The BA design indicates a single-lip oil seal with a metal outer case, ensuring a secure fit in the housing and consistent sealing performance. The primary sealing lip retains oil inside the system, making this oil seal suitable for applications with controlled operating conditions and moderate exposure to contamination.

Manufactured from NBR (nitrile rubber), the seal offers excellent resistance to oils and greases, along with stable mechanical properties across typical operating temperature ranges. NBR material maintains elasticity over time, supporting high durability and long service life during continuous operation.

With precise dimensions of 105x140x12, the seal ensures accurate installation on the shaft and in the housing, which is critical for effective rotary sealing. Compared to double-lip designs, a single-lip BA oil seal provides lower friction and efficient operation in applications where additional dust protection is not required.

The CORTECO 12011063 oil seal is a proven solution for B2B customers seeking reliable performance, long service intervals, and dependable sealing in agricultural machinery, wheel hubs, and drivetrain components.
