CORTECO 12016528 FPM - High-Durability Rotary Shaft Oil Seal

Applications

The CORTECO 12016528 rotary shaft seal is a precision oil seal designed for demanding industrial and automotive environments. With internal diameter 40 mm, outer diameter 55 mm and width 7 mm, this shaft sealing ring fits camshaft, crankshaft or countershaft positions—particularly in gearboxes, engines and rotating assemblies. Constructed from FPM (fluoro-rubber) and featuring a dust-lip design (single or double lip), it delivers top-level performance in shaft seal, oil seal and rotary seal applications. Compatible with a range of OEM references including ABARTH (46434591 / 55195339), ALFA ROMEO (same codes), FIAT, LANCIA, CITROËN (032627), PEUGEOT, TOYOTA (9008031034 / 9031140006 / 9031140013 / 9031140022) and many more, it is ideal for both aftermarket replacements and industrial machine retrofits.

Whether integrated into a bearing housing, mounted as part of a bearing unit or installed standalone in a transmission, this oil seal provides vital barrier protection for rotating shafts and helps prevent lubricant leakage, dust ingress and performance-degrading contamination.

Advantages & Key Benefits

• High durability: The FPM material ensures excellent resistance to oils, greases, fuels and elevated temperatures - supporting long service life in harsh conditions.

• Dust-lip design: The anti-dust lip prevents ingress of contaminants, bolstering reliability in industrial applications and engine systems alike.

• Compact standard size (40x55x7 mm): Facilitates direct replacement in many applications and simplifies stocking for procurement departments.

• Industrial & automotive readiness: Engineered for both engine seal and transmission seal roles, making it versatile for applications in cars, gearboxes and machinery.

• Technical seal solution: As a rotary seal, this product meets requirements for rotary seal, shaft sealing ring, and technical seal applications where tight sealing and low friction are essential.

FAQ - Frequently Asked Questions

Q1: What is the difference between a single-lip oil seal and a dust-lip (anti-dust) seal?
A1: A single-lip oil seal is designed primarily to retain lubricant, whereas a dust-lip or dust-lip design adds an additional barrier against contaminant ingress. This is especially valuable in harsh or high-travel environments where dust, dirt or moisture pose a risk.

Q2: Why is FPM (fluoro-rubber) used for this rotary shaft seal?
A2: FPM provides exceptional resistance to oils, greases, fuels, high temperatures and aggressive chemicals. This makes it ideal for industrial and automotive applications where standard elastomers might degrade or fail prematurely.

Q3: How do I confirm the correct size for a shaft seal?
A3: Measure the shaft diameter to match the inner diameter (d), measure the housing bore for outer diameter (D), and ensure the width (B) aligns with the groove or pocket. In this case 40x55x7 mm is specified.

Q4: Can this seal be used in a bearing housing or part of a bearing unit?
A4: Yes. The seal can be integrated into a bearing housing or used as part of a bearing unit, provided the dimensions and seal type match the assembly requirements.

Q5: What industrial applications are suitable for this seal?
A5: This seal is ideal for engine camshaft or crankshaft sealing in automotive platforms, countershaft sealing in transmissions, as well as industrial equipment with rotating shafts requiring high-durability sealing in oil-rich or dusty environments.
