CORTECO 19035205 17x30x6 ACM HTC Rotary Shaft Seal

AI Overview

The CORTECO 19035205 is a premium rotary shaft seal manufactured to OEM quality standards for Mazda applications requiring OE reference N24518V41. Measuring 17x30x6 mm, this seal features an HTC design with a primary sealing lip and an integrated dust lip for enhanced protection against dirt and contaminants. Manufactured from ACM (Polyacrylate Rubber), it offers excellent resistance to heat, oxidation and modern transmission and engine lubricants, making it ideal for long-term automotive sealing applications.

What Makes This Model Different?

The CORTECO 19035205 has been engineered for reliable sealing under demanding automotive operating conditions.

Key advantages include:

• Genuine CORTECO quality
• OEM reference Mazda N24518V41
• HTC sealing design
• Integrated dust lip
• ACM (Polyacrylate Rubber)
• Excellent heat resistance
• High resistance to transmission oils
• Long service life
• Low friction sealing lip
• Precision manufactured dimensions

Its compact design and durable sealing material provide excellent protection against lubricant leakage while extending component life.

Construction and Operating Principle

The rotary shaft seal consists of:

• Precision sealing lip
• Dust protection lip
• Reinforced metal insert
• Elastomer sealing body
• Spring-loaded sealing element

During operation, the sealing lip maintains constant radial pressure against the rotating shaft, creating a reliable oil-tight barrier while minimizing friction and wear.

The auxiliary dust lip prevents contamination from reaching the primary sealing edge, improving durability in harsh operating environments.

Material Properties

The seal is manufactured from ACM (Polyacrylate Rubber).

Material benefits include:

• Excellent resistance to high temperatures
• Outstanding oxidation resistance
• Very good resistance to transmission oils
• Good resistance to engine oils
• Excellent ageing resistance
• Low compression set
• High wear resistance
• Stable performance during continuous operation

ACM is widely used in modern automotive powertrain sealing where elevated temperatures exceed the capabilities of conventional NBR materials.

Typical Automotive Applications

Typical applications include:

• Crankshaft sealing
• Transmission input shafts
• Auxiliary drive shafts
• Gearbox assemblies
• Timing system components
• Automotive powertrain assemblies
• Passenger vehicles
• OEM engine rebuilding
• Transmission servicing
• Automotive maintenance

Typical Failure Symptoms

Replacement is recommended if the following symptoms occur:

• Oil leakage
• Lubricant contamination
• Hardened sealing lip
• Excessive shaft wear
• Visible seal damage
• Oil traces around the housing
• Increased oil consumption
• Contamination entering the assembly

Recommended During Repair

During installation it is recommended to inspect:

• Shaft surface condition
• Housing bore
• Shaft runout
• Installation depth
• Lubrication condition
• Ventilation system
• Adjacent bearings
• Mating components
• Installation tools
• Shaft wear sleeve if applicable

FAQ

What does HTC mean?

HTC indicates a rotary shaft seal with a primary sealing lip and an additional dust lip for improved contamination protection.

Why is ACM used instead of NBR?

ACM provides significantly better resistance to elevated temperatures, oxidation and modern transmission oils.

Is the seal supplied ready for installation?

Yes. The seal is supplied ready for professional installation using appropriate mounting tools.

Can this seal be used as an OEM replacement?

Yes. It is designed for applications requiring Mazda OEM number N24518V41.

Should the shaft be inspected during seal replacement?

Yes. Worn or damaged shaft surfaces can reduce sealing performance and shorten seal service life.
