CORTECO 20029771 TFE BAPTSLRSX7 154x180x12 – Radial Shaft Oil Seal for DAF

Technical specifications

The product identification details are based on the supplied designation and reference numbers.

Construction and operating parameters that have not been verified against CORTECO documentation must not be inferred from the general characteristics of similar shaft seals.

Understanding the CORTECO 20029771 designation

What does TFE mean?

The TFE designation is associated with fluoropolymer materials used in technical sealing applications.

Depending on the manufacturer's product classification, it may refer to a material used in the sealing element.

However, TFE should not automatically be interpreted as a specific PTFE grade, compound formulation, filler composition or operating temperature range.

The exact material specification of CORTECO 20029771 must be confirmed using the manufacturer's technical documentation.

What does BAPTSLRSX7 mean?

BAPTSLRSX7 identifies a particular seal design or profile.

Its construction may involve specific sealing lip geometry, contact characteristics and additional design features.

Without the manufacturer's documentation for part number 20029771, the following cannot be reliably confirmed:

• Number of sealing lips.

• Presence of a garter spring.

• Directional hydrodynamic features.

• Outer case construction.

• Additional protective sealing elements.

The complete BAPTSLRSX7 designation should be preserved when identifying and ordering the product.

Construction and operating principle

A radial shaft oil seal provides a sealing interface between a rotating shaft and a stationary housing.

Its primary purpose is to limit lubricant leakage and, depending on the design, reduce the entry of external contaminants into the mechanical assembly.

Main sealing functions

• Sealing the contact area around a rotating shaft.

• Limiting leakage of oil or another compatible operating medium.

• Operating against a suitably prepared shaft surface.

• Maintaining sealing performance within specified speed, temperature and pressure conditions.

Actual sealing performance depends on the lip geometry, sealing material, lubrication conditions and installation quality.

Importance of sealing lip geometry

The geometry of the sealing lip influences contact pressure, friction, lubricant retention and wear.

Different shaft seal profiles may require different installation methods and operating conditions.

For this reason, the BAPTSLRSX7 profile must be considered an essential part of the product identification.

Mounting dimensions – 154x180x12 mm

The nominal dimensions do not replace the manufacturer's requirements for shaft and housing tolerances.

Before installation, additional factors must be checked, including:

• Shaft surface roughness.

• Radial shaft runout.

• Shaft-to-housing alignment.

• Condition of the sealing contact surface.

• Housing bore geometry.

• Installation depth.

DAF OE reference numbers

The following DAF reference numbers have been supplied for this product:

These numbers are provided as product identification references.

Their association with CORTECO 20029771 and their mutual equivalence should be verified using the CORTECO catalogue or official DAF parts documentation.

Selecting the seal by OE number

When selecting a replacement seal for a DAF vehicle, compare:

• The part number of the removed seal.

• The OE number assigned to the specific vehicle.

• The complete CORTECO designation 20029771.

• Nominal dimensions 154x180x12 mm.

• BAPTSLRSX7 profile.

• Sealing material.

• Direction of rotation, if the seal has directional features.

• Manufacturer-specific installation requirements.

Matching nominal dimensions alone does not guarantee correct product selection.

Operating conditions and technical limitations

The following operating parameters have not been confirmed for the exact CORTECO 20029771 version:

General operating limits for PTFE materials or conventional elastomeric shaft seals should not be assigned to this specific product without confirmation.

Factors affecting sealing performance

The operating life of a radial shaft seal depends on several interacting conditions:

• Shaft rotational speed.

• Temperature at the sealing contact.

• Lubricant properties.

• Pressure differences.

• Shaft surface condition.

• Radial runout.

• Installation accuracy.

• Contamination.

• Compatibility between the sealing material and operating medium.

These factors should be assessed together when selecting a replacement seal.

Applications of CORTECO 20029771

The product is identified using the supplied DAF reference numbers.

It may be considered for maintenance of corresponding mechanical assemblies in DAF vehicles, provided catalogue compatibility is confirmed.

Typical functions of radial shaft oil seals include sealing rotating components in:

• Power transmission assemblies.

• Mechanical gearboxes.

• Rotating shaft mechanisms.

• Assemblies requiring lubricant retention.

These are general application categories for radial shaft seals, not confirmed installation positions for CORTECO 20029771.

The exact OE application and mounting location require verification.

Comparison of shaft seal selection criteria

Technical conclusion: shaft seals with identical nominal dimensions are not necessarily interchangeable.

Differences in material, lip geometry, directional features and installation requirements can significantly affect sealing performance.

Product selection and interchangeability

Before ordering, verify:

• CORTECO as the manufacturer.

• Manufacturer part number 20029771.

• Complete designation TFE BAPTSLRSX7.

• Dimensions 154x180x12 mm.

• Relevant DAF OE reference.

• Compatibility with the specific mechanical assembly.

• Shaft contact surface requirements.

• Sealing lip material and geometry.

• Direction of rotation requirements.

• Lubrication conditions.

• Operating temperature and pressure.

• Manufacturer's installation instructions.

When evaluating alternatives, complete technical specifications must be compared rather than nominal dimensions alone.

Why is the exact profile important?

Two seals may share the same inside diameter, outside diameter and width while using different lip materials or sealing geometries.

Such differences may affect:

• Contact pressure.

• Friction.

• Heat generation.

• Lubricant compatibility.

• Directional sealing performance.

• Installation procedure.

The exact BAPTSLRSX7 profile therefore remains an essential selection criterion.

Installation recommendations

Before installation, inspect the shaft, housing and seal.

Recommended procedures include:

• Cleaning the housing bore.

• Inspecting the shaft contact surface.

• Removing burrs and sharp edges.

• Verifying nominal dimensions and mounting tolerances.

• Determining the correct installation orientation.

• Using suitable tools to press the seal evenly into position.

• Protecting the sealing lip from mechanical damage.

• Following the manufacturer's instructions for lip preparation.

• Checking the installed axial position.

• Verifying sealing performance after the equipment is restarted.

Important considerations for fluoropolymer sealing materials

Certain PTFE sealing lip designs require dry installation and a specified stabilization period before operation.

Other seal constructions may require different preparation procedures.

Do not lubricate the sealing lip or install it dry without first confirming the instructions applicable to CORTECO 20029771.

Incorrect installation can damage the sealing lip or compromise sealing performance.
