Simrit 40x68x14 COMBI NBR Rotary Shaft Seal

Reliable Rotary Sealing for Gearboxes and Drive Systems

COMBI Design - Enhanced Stability and Oil Retention

Technical Dimensions and Application Range

Main Description:
The Simrit 40x68x14 COMBI NBR rotary shaft seal is a high-quality oil seal engineered for demanding industrial and automotive applications. Designed as a reinforced shaft sealing ring, it serves as a reliable replacement for Corteco 12013319 while maintaining full dimensional compatibility and operational performance.

The size 40x68x14 indicates a shaft diameter of 40 mm, housing bore diameter of 68 mm and seal width of 14 mm. The COMBI construction features a rigid metal case combined with optimized sealing lip geometry, ensuring improved seating stability and efficient oil retention. Compared to a standard single lip oil seal (SC) or a classic double lip oil seal (TC), the COMBI design offers enhanced structural strength and better resistance to vibration and dynamic loads.

Manufactured from high-quality NBR elastomer, this rotary oil seal provides strong resistance to oils and grease, ensuring high durability in lubricated systems. The flexible sealing lip maintains consistent radial pressure against the shaft surface, minimizing leakage and reducing wear. It effectively protects adjacent components such as bearings and rotating shafts, extending overall system lifespan.

This rotary shaft seal is commonly used in gearboxes, drive axles, reduction units and other industrial applications requiring dependable technical sealing. It can function as an engine seal or transmission seal in automotive systems and as a robust industrial oil seal in heavy machinery. For B2B customers, it represents a reliable, cost-effective solution for maintaining equipment efficiency and reducing downtime.
