BASL Design - Primary Sealing Lip and Additional Dust Lip

The CORTECO 12011159 features a BASL-type construction used in radial shaft sealing applications.

Primary Sealing Lip

The primary sealing lip contacts the rotating shaft surface and creates a sealing interface designed to reduce lubricant leakage from the mechanical assembly.

Its effectiveness depends on appropriate lip contact pressure, shaft surface quality, lubrication and operating conditions.

Additional Dust Protection Lip

The additional dust lip is positioned toward the external side of the sealing arrangement.

Its function is to help prevent dust, dirt and other contaminants from reaching the primary sealing lip.

This design can be particularly useful in mechanical assemblies exposed to contamination during operation.

However, the presence of a dust lip does not automatically mean the seal is suitable for every dusty environment or for submerged operation.

Seal Body Construction

The BASL design combines elastomeric sealing components with structural elements that provide appropriate installation and retention within the housing.

Exact construction details, including the spring specification, reinforcement materials and internal geometry, should be confirmed using the manufacturer's documentation for this specific part number.

NBR Material - Properties of Nitrile Butadiene Rubber

NBR is one of the most widely used elastomers in industrial rotary shaft seals.

Resistance to Oils and Lubricants

NBR is commonly used in contact with many mineral oils and industrial lubricants.

For this reason, nitrile rubber shaft seals are frequently selected for mechanical assemblies requiring lubricant retention.

However, exact compatibility depends on:

• Type of oil or grease.

• Chemical additives.

• Operating temperature.

• Exposure duration.

• Formulation of the specific NBR compound.

Mechanical Resistance

NBR offers mechanical properties suitable for many rotary shaft sealing applications.

Seal durability also depends on shaft surface roughness, shaft hardness, lubrication and correct installation.

Operating Temperature Range

NBR can be used within a temperature range determined by its specific compound formulation.

Exact minimum and maximum operating temperatures should not be assigned to CORTECO 12011159 without confirmation from the manufacturer's technical documentation.

Chemical Limitations

NBR is not resistant to every chemical substance.

Before using the seal with fuels, solvents, aggressive chemicals or unusual operating fluids, material compatibility must be verified.

Typical Applications of 40x62x7 NBR BASL Shaft Seals

Radial shaft seals with dimensions of 40x62x7 mm and BASL construction may be used in appropriately designed mechanical assemblies.

Potential applications include:

• Mechanical gearboxes.

• Drive assemblies.

• Rotating shaft housings.

• Agricultural machinery mechanisms.

• Industrial machine components.

• Systems requiring oil or lubricant retention.

• Mechanical assemblies requiring additional dust protection.

These are general examples of applications for this type of rotary shaft seal.

How to Select a Replacement for CORTECO 12011159

When selecting a replacement shaft seal, more than the nominal dimensions must be considered.

The most important parameters include:

1. CORTECO part number 12011159 or a verified original equipment reference.

2. Shaft diameter of 40 mm.

3. Housing bore diameter of 62 mm.

4. Seal width of 7 mm.

5. BASL construction with an additional dust lip.

6. NBR elastomer material.

7. Type and properties of the sealed medium.

8. Operating temperature, rotational speed and pressure.

9. Shaft rotation direction, if the original seal incorporates directional features.

10. Condition of the shaft surface and housing bore.

Can a 40x62x7 BASL Seal Be Replaced with a BA-Type Seal?

Interchangeability should not be assumed.

A BASL-type seal includes an additional dust protection lip that may not be present in a standard BA-type design.

Removing the dust lip may reduce protection against contamination under certain operating conditions.

Can a 40x62x8 Seal Replace a 40x62x7 Seal?

Not automatically.

The difference in axial width is 1 mm and may affect the sealing lip position on the shaft and correct installation within the housing.

Before changing the seal width, verify the housing depth and geometry of the entire assembly.

Can an NBR Shaft Seal Be Replaced with an FKM Seal?

This may be possible in certain applications, but it requires verification of construction, dimensions, material compatibility and operating conditions.

The use of FKM alone does not guarantee that a replacement seal will be suitable for the specific equipment.

Installation of CORTECO 12011159

Correct installation is essential for reliable radial shaft sealing and service life.

Preparing the Shaft and Housing

Before installation:

• Clean the shaft surface.

• Check the shaft for scratches, grooves and corrosion.

• Inspect the housing bore.

• Remove contaminants and burrs.

• Confirm the required dimensions of 40x62x7 mm.

Correct Seal Installation

The oil seal should be pressed evenly into the housing using an appropriate installation tool that does not deform the seal body.

The primary sealing lip should face the correct direction according to the assembly design, normally toward the lubricant being retained.

Before operation, ensure appropriate lubrication of the sealing lip contact area in accordance with the manufacturer's recommendations.

Common Installation Mistakes

• Installing the seal at an angle.

• Damaging the sealing lip on sharp shaft edges.

• Using an incorrect seal size.

• Installing the seal on a worn shaft surface.

• Incorrect orientation of the primary sealing lip.

• Insufficient initial lubrication.

• Applying excessive installation force.
