CORTECO 12011577 NBR BASL 40x56x8 Oil Seal

Rotary Shaft Seal for Engines and Industrial Machinery

Double-Lip Oil Seal with High Durability

Main Product Description

The CORTECO 12011577 NBR BASL 40x56x8 oil seal is a high-quality rotary shaft seal designed for reliable shaft sealing in engines, agricultural machinery, and industrial applications. This model is commonly used in equipment from manufacturers such as Iveco, Claas, SAME, and Lamborghini, where durable and precise technical sealing is required.

The BASL design indicates a double-lip oil seal with an additional dust lip. The primary sealing lip ensures effective oil retention, while the secondary lip protects the system against external contaminants. This configuration significantly improves sealing performance compared to a single-lip oil seal, especially in environments exposed to dirt, dust, and variable operating conditions.

Manufactured from NBR rubber, the seal offers excellent resistance to oils, greases, and standard operating fluids, along with stable mechanical properties in typical engine and machinery temperature ranges. The material maintains elasticity over time, ensuring consistent sealing performance and high durability during continuous operation.

With precise dimensions of 40x56x8, the oil seal provides accurate fitment on the shaft and in the housing, which is essential for long service life and leak-free operation. This seal is suitable for industrial applications, engine assemblies, gear units, and rotating equipment where dependable rotary sealing is critical.

The CORTECO 12011577 oil seal is a professional solution for B2B customers seeking reliable performance, long service intervals, and reduced maintenance costs in demanding mechanical systems.
