Main Description

The CORTECO shaft seal 12010979 NBR BA 52x85x10 is a high-quality rotary shaft seal (oil seal) designed for sealing rotating shafts in engines, agricultural machinery, and industrial applications. This shaft sealing ring effectively prevents oil leakage while protecting mechanical systems against external contamination.

Manufactured from NBR (nitrile butadiene rubber), the seal offers excellent resistance to oils, grease, and fuels, ensuring stable performance in typical operating temperature ranges found in engines and machinery. NBR is widely used in technical sealing solutions due to its reliability, cost efficiency, and long service life in standard oil-based environments.

The BA design indicates a single lip oil seal with a metal outer case, providing secure seating in the housing and consistent shaft contact. This construction ensures effective rotary sealing with low friction and reduced wear. As a single lip oil seal, it is suitable for applications where dust protection is not critical but dependable oil retention is required.

The CORTECO 12010979 oil seal is commonly used as an engine seal and machine shaft seal, particularly in agricultural equipment and drivetrains. It is compatible with machinery from manufacturers such as DANA, LANDINI, MASSEY FERGUSON, and MCCORMICK, making it a practical solution for maintenance, repair, and OEM replacement in professional B2B environments.
