CORTECO 49364109 BASLSFRDX67 85x130x16.5 FPM Oil Seal

Premium Differential Shaft Oil Seal for Heavy-Duty Commercial Vehicles

The CORTECO 49364109 BASLSFRDX67 is a premium rotary shaft oil seal engineered for differential and heavy-duty drivetrain applications. Manufactured from a combination of FPM (FKM fluoroelastomer) and ACM (polyacrylate rubber), it provides outstanding resistance to heat, transmission oils and long-term mechanical wear. The seal features a right-hand hydrodynamic helix, a spring-loaded primary sealing lip and an integrated dust lip to maximize sealing efficiency while preventing contamination. It is an OEM replacement for RENAULT TRUCKS 5010534863.

Application in Industrial Systems

The CORTECO 49364109 is designed for demanding rotating equipment operating under heavy loads.

Typical applications include:

• Differentials
• Drive axles
• Final drives
• Heavy-duty transmissions
• Industrial gearboxes
• Commercial vehicle drivetrains
• Agricultural machinery
• Construction equipment
• Mining machinery
• Heavy industrial rotating equipment

OEM Reference:

• RENAULT TRUCKS 5010534863

Construction and Design

The BASLSFRDX67 profile has been developed for reliable sealing in heavy-duty operating conditions.

Key design features include:

• Rotary shaft oil seal
• Differential shaft seal
• Spring-loaded primary sealing lip
• Integrated dust lip
• Right-hand hydrodynamic helix
• Rubber-covered outer diameter
• Reinforced steel insert
• Precision sealing lip geometry

The right-hand hydrodynamic helix actively returns lubricant toward the sealing zone during shaft rotation, reducing oil leakage and extending seal life.

Material Properties

The sealing element combines FPM (FKM) and ACM elastomers.

Material advantages include:

• Excellent high-temperature resistance
• Outstanding transmission oil resistance
• Excellent ageing resistance
• High wear resistance
• Good chemical resistance
• Ozone resistance
• Long operational life
• Stable sealing performance

The FPM/ACM combination provides superior durability in heavy-duty drivetrain applications where standard NBR seals are not sufficient.

FAQ

What does BASLSFRDX67 mean?

It identifies a radial shaft seal with a spring-loaded sealing lip, an integrated dust lip and a right-hand hydrodynamic helix designed to improve lubricant return during shaft rotation.

Why is FPM/ACM material used?

The FPM/ACM combination provides superior resistance to heat, transmission oils, oxidation and ageing, making it ideal for heavy-duty drivetrain applications.

Which OEM number does this seal replace?

It replaces RENAULT TRUCKS OEM 5010534863.

Does the seal include a dust protection lip?

Yes. The integrated dust lip helps prevent dirt, moisture and contaminants from entering the sealing area.

What is the purpose of the right-hand hydrodynamic helix?

It actively returns lubricant toward the sealing lip during shaft rotation, improving sealing performance and reducing oil leakage.
