CORTECO 01003358 75x95x10 NBR B2 - Radial Shaft Seal Simmerring

CORTECO 01003358 NBR B2 - Technical Characteristics

The CORTECO 01003358 radial shaft seal is designed to seal the interface between a rotating shaft and a stationary housing.

The primary sealing lip maintains dynamic contact with the shaft surface, helping prevent leakage of the retained medium.

The B2 construction is distinguished by its exposed metal outer surface and additionally reinforced metal case. Compared with seals featuring a rubber-covered outside diameter, this design has different installation and static sealing characteristics within the housing bore.

Correct selection requires verification of the 75x95x10 mm dimensions, B2 profile, NBR sealing material and operating conditions.

CORTECO 01003358 - Dimensions

The 75 mm inside diameter corresponds to the nominal shaft diameter.

The 95 mm outside diameter corresponds to the nominal housing bore diameter.

The 10 mm width defines the axial dimension of the seal.

These nominal dimensions do not replace the requirements for housing tolerances, shaft surface condition or installation fit.

What Does CORTECO 01003358 NBR B2 Mean?

CORTECO - The brand under which the radial shaft seal is supplied.

01003358 - The product reference number used in the CORTECO dimensional catalogue.

75x95x10 - Nominal dimensions in millimetres: inside diameter, outside diameter and axial width.

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

B2 - Radial shaft seal profile featuring an exposed metal outside diameter, an additionally reinforced metal case and a spring-loaded primary sealing lip.

The B2 designation does not include the SL suffix, which identifies an additional dust lip in the corresponding B2SL construction.

B2 Simmerring Construction

Exposed Metal Outer Surface

The B2 profile features a metal outside diameter.

This construction differs from seals with a rubber-covered outside surface. Housing bore tolerances, surface condition and uniform installation are particularly important for achieving the intended fit and static sealing performance.

Reinforced Metal Case

The B2 profile incorporates additional metal reinforcement.

This construction provides increased case rigidity and helps maintain the seal's geometry during correct installation.

However, a reinforced metal case does not compensate for an incorrectly dimensioned or damaged housing bore.

Primary Sealing Lip

The primary sealing lip is manufactured from NBR elastomer and operates in contact with the rotating shaft surface.

Its function is to restrict leakage of the retained medium while maintaining the required dynamic sealing contact.

Garter Spring

The standard B2 construction uses a circumferential garter spring to support the contact pressure of the primary sealing lip.

The spring helps maintain sealing contact during shaft rotation.

No Auxiliary Dust Lip

The standard B2 profile does not incorporate the additional dust lip identified by the SL suffix.

This is an important distinction between the B2 and B2SL constructions.

NBR - Nitrile Butadiene Rubber

The CORTECO 01003358 uses NBR, also known as nitrile rubber, as its sealing elastomer.

NBR is widely used in radial shaft seals designed to operate with compatible oils and lubricants.

Its performance depends on the specific rubber compound, including acrylonitrile content, curing system and additives.

Therefore, the NBR designation alone does not establish the exact operating temperature range, hardness, maximum shaft speed or compatibility with every operating medium.

These parameters must be verified against the technical documentation for the specific seal.

CORTECO 01003358 B2 vs Other Seal Profiles

The comparison describes the basic structural differences between these seal profiles.

B2 and B2SL are not identical seals. The B2SL version incorporates an additional auxiliary dust lip, affecting the sealing geometry and contact conditions.

The BA profile has a rubber-covered outside diameter and may require different housing installation conditions from the B2 design.

Matching nominal dimensions of 75x95x10 mm do not automatically establish full interchangeability.

Alternative Designations and Reference Numbers

The designation 01003358B appears in distributor catalogues for an NBR B2 seal with nominal dimensions of 75x95x10 mm.

Before ordering, the complete product reference should be checked against the relevant catalogue documentation.

The FENDT reference does not establish compatibility with every machine or tractor model manufactured by FENDT.

Selection and Interchangeability of CORTECO 01003358

Before purchasing a replacement, verify:

1. CORTECO reference number: 01003358.

2. Nominal shaft diameter: 75 mm.

3. Nominal housing bore diameter: 95 mm.

4. Axial seal width: 10 mm.

5. Sealing elastomer: NBR.

6. Construction profile: B2.

7. Exposed metal outside diameter and reinforced case.

8. Operating medium and service conditions.

9. Shaft surface condition and housing bore requirements.

10. Any equipment-specific installation requirements.

The B2 seal should not automatically be replaced with a BA, B1, B2SL or another seal of identical nominal dimensions.

When selecting a replacement by machine part number, compatibility must also be verified using the relevant service documentation or parts catalogue.

Applications of CORTECO 01003358

CORTECO 01003358 belongs to the category of radial shaft seals designed for dynamic sealing between a rotating shaft and a stationary housing.

The CORTECO dimensional catalogue associates this reference with FENDT applications. Parts catalogues also list the reference X552245609000.

However, this does not confirm compatibility with every FENDT tractor or machine.

Selection for a particular application should be based on the original part number, equipment documentation and required sealing construction.

Installation and Operating Considerations

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

Check for scratches, corrosion, burrs and wear grooves in the sealing contact area.

Because the B2 profile has a metal case, the seal should be pressed evenly into the housing using a suitable installation tool.

Installation force must not be applied directly to the sealing lip or garter spring.

Protect the sealing lip when passing it over sharp shaft edges, keyways or splines.

In conventional oil-retaining arrangements, the primary spring-loaded sealing lip faces the retained medium unless the equipment documentation specifies otherwise.

Installation lubrication must be compatible with the NBR elastomer and the operating medium.

Store the seal in a clean environment and protect it from deformation, contamination and unsuitable storage conditions.
