Rotary Shaft Seal CORTECO 12019137 FPM CASSETTE 140x170x14.5/16

Product Overview

The CORTECO 12019137 is a rotary shaft seal (oil seal) in a cassette construction, designed for demanding industrial and automotive applications where enhanced protection and long service life are required. Manufactured from FPM (FKM) fluoroelastomer, this seal offers outstanding resistance to high temperatures, oils, synthetic lubricants, fuels, and hydraulic fluids.
The cassette design integrates sealing surfaces inside the assembly, improving durability and reducing shaft wear in harsh operating environments with contaminants such as dust, mud, or moisture.

Applications

This rotary oil seal 140x170x14.5/16 is commonly used in:
• Heavy machinery drives and gearboxes
• Agricultural and off-road equipment
• Industrial transmission systems
• Automotive and commercial vehicle axles & powertrains
• Hydraulic systems exposed to abrasive conditions

Its construction ensures effective sealing even in rotating and oscillating shaft operations, where precision and reliability are essential.

Key Advantages

• Cassette structure provides built-in protection of sealing lips and running surface
• High durability in contaminated environments
• FPM material guarantees excellent heat and oil resistance
• Designed to reduce shaft wear, extending component lifespan
• Suitable for continuous heavy-duty operation

FAQ

1. What is the advantage of a cassette oil seal over a standard oil seal?
Cassette seals include a protected sealing surface inside the assembly, which significantly reduces shaft wear and improves performance in dirty or abrasive environments.

2. Why choose FPM (FKM) material?
FPM provides superior resistance to heat, oils, synthetic lubricants, fuels, and chemicals, making it ideal for heavy-duty applications.

3. How do I confirm that the shaft size matches this seal?
Check the shaft diameter (140 mm) and housing bore (170 mm). The seal must fit both precisely for optimal performance.

4. Can this seal be used in high-speed applications?
Yes, provided the speed and temperature limits are within the recommended operating specifications.
