CORTECO 01029799 NBR B1SLSF 80x120x11/22.5 mm - Radial Shaft Seal Simmerring

CORTECO 01029799 B1SLSF - Technical Characteristics

CORTECO 01029799 is a radial shaft seal designed to seal the interface between a rotating shaft and a stationary housing.

Unlike conventional radial shaft seals specified with a single axial width, this product has two axial dimensions: 11 mm and 22.5 mm. These dimensions are associated with the special geometry of the B1SLSF profile.

The sealing elastomer is NBR. An additional dust lip helps restrict external contamination from entering the primary sealing area.

Correct selection requires the complete dimensional designation 80x120x11/22.5 mm. Omitting the second axial dimension may result in the selection of an incorrectly configured replacement seal.

CORTECO 01029799 - Dimensions

The 80 mm inside diameter corresponds to the nominal shaft diameter.

The 120 mm outside diameter corresponds to the nominal housing bore diameter.

The 11 mm and 22.5 mm values identify two axial dimensions of the seal construction.

Without the manufacturer's technical drawing, these dimensions should not be assigned specific measurement reference points. In particular, the 22.5 mm dimension should not automatically be interpreted as the width of the entire metal case.

What Does CORTECO 01029799 NBR B1SLSF Mean?

CORTECO - The product brand associated with the Freudenberg Group.

01029799 - The product reference number used in the CORTECO catalogue.

NBR - Nitrile butadiene rubber, the elastomer used for the sealing element.

B1SLSF - The complete construction designation identifying a special radial shaft seal profile with a metal case and additional dust protection.

B1 - The basic construction family featuring an exposed metal outer surface.

SL - A designation used in radial shaft seal nomenclature for an additional auxiliary dust lip.

SF - An additional designation identifying a special execution within the B1SLSF profile. Its precise geometry must be interpreted using the manufacturer's technical drawing rather than assumptions based on other profiles.

80x120x11/22.5 - The nominal inside diameter, outside diameter and two axial dimensions.

The complete B1SLSF designation is technically significant and should not be shortened to B1SL or B1.

B1SLSF Radial Shaft Seal Construction

Metal Outer Case

The B1 profile belongs to a family of radial shaft seals with an exposed metal outer surface.

This construction requires a correctly prepared housing bore and suitable installation fit.

Housing bore geometry, tolerances and surface condition influence the correct seating and static sealing performance of the seal.

Primary Sealing Lip

The primary sealing lip operates in dynamic contact with the rotating shaft surface.

Its function is to restrict leakage of the retained medium from the sealed assembly.

Sealing performance depends on the lip geometry, elastomer properties, shaft surface condition and lubrication conditions.

Additional Dust Protection

Catalogue information for CORTECO 01029799B confirms the presence of an additional dust lip.

This element helps reduce the entry of external contaminants into the primary sealing area.

However, the presence of an auxiliary dust lip does not automatically establish a specific IP protection rating or suitability for continuous water immersion.

Special Axial Geometry

The two axial dimensions of 11 mm and 22.5 mm distinguish CORTECO 01029799 from standard 80x120 mm radial shaft seals with a single specified width.

When replacing the seal, the available installation space, location of the sealing contact surfaces and original seal geometry must be checked.

NBR - Nitrile Butadiene Rubber

CORTECO 01029799 uses NBR, commonly known as nitrile rubber, as its sealing elastomer.

NBR is widely used in technical sealing applications involving compatible oils and lubricants.

The properties of a specific NBR compound depend on its formulation and operating conditions.

The NBR designation alone does not establish:

• The exact operating temperature range.

• Maximum permissible shaft speed.

• Allowable operating pressure.

• Elastomer hardness.

• Compatibility with every oil or chemical substance.

These characteristics require manufacturer-specific technical data for the exact product.

CORTECO 01029799 B1SLSF vs Other Seal Profiles

B1SLSF is not automatically interchangeable with B1SL or B1.

Differences may involve sealing geometry, lip arrangement and installation space requirements.

CORTECO 01029799 should not be replaced with a standard 80x120x11 mm seal solely because the nominal diameters and first axial dimension are identical.

Alternative Designations and Reference Numbers

The following catalogue and commercial references are associated with this product:

• CORTECO 01029799

• CORTECO 01029799B

• CORTECO 82029799

• CORTECO B1SLSF 80x120x11/22.5

• CORTECO 80x120x11/22.5 NBR B1SLSF

Associated FENDT reference: X550151501000

The 01029799B designation appears in replacement parts catalogues for this seal.

The reference 82029799 is also used as an alternative commercial product number.

The FENDT reference X550151501000 is associated with CORTECO 01029799B in parts catalogues. Compatibility with a specific machine model must be verified using the appropriate parts documentation.

Applications of CORTECO 01029799

The CORTECO dimensional catalogue associates reference 01029799 with FENDT machinery.

Replacement parts catalogues also identify the FENDT reference X550151501000.

This is a documented catalogue association, but it does not establish compatibility with every FENDT tractor or machine.

Selection for a particular application should be based on the original equipment part number, technical documentation and compatibility with the B1SLSF profile and 80x120x11/22.5 mm dimensions.

Selection and Interchangeability

Before ordering CORTECO 01029799, verify:

1. Product reference: 01029799 or 01029799B.

2. Nominal shaft diameter: 80 mm.

3. Nominal housing bore diameter: 120 mm.

4. Both axial dimensions: 11 mm and 22.5 mm.

5. Complete sealing profile: B1SLSF.

6. Sealing material: NBR.

7. Requirements for additional dust protection.

8. Housing geometry and available installation space.

9. Operating medium and service conditions.

10. Original equipment reference number, where available.

Matching the 80 mm and 120 mm diameters does not establish full interchangeability.

For this product, the B1SLSF profile and second axial dimension of 22.5 mm are particularly important.

Installation and Operating Considerations

Before installation, thoroughly clean the housing bore and the shaft surface.

Inspect the shaft for burrs, corrosion, sharp edges and wear grooves in the sealing contact area.

A metal-cased radial shaft seal should be installed evenly using an appropriate fitting tool.

Installation force must not be applied directly to the sealing lips, and the additional dust protection element must not be deformed.

During installation, account for both axial dimensions and ensure that the special profile does not interfere with adjacent machine components.

Lubrication and seal orientation must comply with the requirements of the specific equipment.

The seal should be stored in a clean environment and protected from contamination, mechanical deformation and unsuitable storage conditions.
