Product Description

The CORTECO 12037245 is a premium rotary shaft seal engineered for high-performance industrial and automotive machinery. Manufactured from NBR (Nitrile-Butadiene Rubber), this oil seal provides exceptional resistance to oils, greases, and chemical exposure, ensuring long-term reliability in heavy-duty applications. It is suitable for DEUTZ-FAHR (215291690) and SAME (215291690) equipment, making it ideal for tractors, engines, transmissions, and hydraulic systems.

Key advantages of this shaft sealing ring include:

• High durability and wear resistance - NBR material withstands high rotational speeds, temperature fluctuations, and long-term mechanical stress.

• Enhanced oil and grease resistance - suitable for engine, transmission, and hydraulic applications where fluid retention is critical.

• Precise dimensions for secure fit - inner diameter 100 mm, outer diameter 129.85 mm, width 12.5/14 mm, providing optimal sealing performance.

• Versatile applications - compatible with industrial machinery, agricultural engines, drive systems, and other rotating assemblies requiring robust rotary seals.

This CORTECO oil seal is designed to perform reliably under continuous rotation, reducing maintenance cycles and downtime. Its design ensures effective sealing for single-lip (SC) and double-lip (TC) configurations, offering protection against leakage, contamination, and premature wear.

FAQ - Frequently Asked Questions

Q: What is the difference between a single lip and double lip oil seal?
A: Single-lip seals (SC) protect against oil leakage in standard applications, while double-lip seals (TC) offer additional protection against dust, dirt, and contamination, ideal for harsh environments.

Q: Which materials are best for oil and chemical resistance?
A: NBR, FKM, and silicone are commonly used. NBR is ideal for oils, greases, and moderate temperatures, ensuring durability in engines and industrial machinery.

Q: How do I select the correct shaft seal size?
A: Choose based on shaft diameter, housing bore, and width. Proper fit is essential for optimal sealing performance and long service life.

Q: Can this seal be used in agricultural machinery?
A: Yes, the CORTECO 12037245 NBR seal is compatible with DEUTZ-FAHR and SAME tractors and other agricultural equipment.

Q: Is installation difficult?
A: Proper installation requires alignment in the housing and light lubrication on the seal lip to prevent damage during assembly.
