CORTECO 12010936 NBR BA 40x62x10 mm - Radial Shaft Seal Simmerring

CORTECO 12010936 NBR BA - Technical Characteristics

CORTECO 12010936 is a radial shaft seal designed to restrict lubricant leakage at the interface between a rotating shaft and a stationary housing.

The BA profile is distinguished by its rubber-covered outside diameter. This construction provides static sealing between the outer surface of the seal and the housing bore.

The primary sealing lip operates in dynamic contact with the shaft surface. A circumferential garter spring helps maintain the required sealing contact pressure.

The NBR elastomer is commonly used in sealing applications involving compatible oils and lubricants.

This product has catalogue associations with power transmission assemblies, including differentials and automatic transmissions.

CORTECO 12010936 - Dimensions

The 40 mm inside diameter corresponds to the nominal shaft diameter.

The 62 mm outside diameter corresponds to the nominal housing bore diameter.

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

Nominal dimensions alone do not establish the required installation tolerances or permissible shaft surface wear.

What Does CORTECO 12010936 NBR BA Mean?

CORTECO - A technical sealing products brand associated with the Freudenberg Group.

12010936 - The catalogue reference identifying the specific radial shaft seal.

40x62x10 - Nominal dimensions in millimetres, expressed as inside diameter, outside diameter and axial width.

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

BA - A radial shaft seal profile with a rubber-covered outside diameter and a spring-loaded primary sealing lip.

The standard BA profile does not include the additional auxiliary dust lip identified by the SL suffix.

BA Radial Shaft Seal Construction

Rubber-Covered Outer Surface

The BA profile incorporates a metal supporting case covered externally with elastomer.

The rubber covering provides static sealing between the seal and the housing bore.

It can also accommodate minor housing surface irregularities within the limits permitted by the seal design and installation requirements.

Primary Sealing Lip

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

Its function is to retain the operating lubricant within the sealed assembly.

Correct performance requires a suitable shaft surface condition, proper lubrication and material compatibility.

Garter Spring

The standard BA construction incorporates a circumferential garter spring supporting the primary sealing lip.

The spring helps maintain sealing contact between the elastomer and the shaft during operation.

No Additional Dust Lip

The standard BA profile does not incorporate an auxiliary dust lip.

Variants offering additional protection against external contamination must be identified by their complete construction designations.

NBR - Nitrile Butadiene Rubber

NBR, also known as nitrile rubber, is an elastomer widely used in radial shaft sealing applications.

It is commonly used in assemblies operating with compatible mineral oils and lubricants.

Actual chemical resistance and permissible operating conditions depend on the specific rubber compound.

The NBR designation alone does not establish the exact operating temperature range, permissible pressure, maximum shaft surface speed or elastomer hardness.

For automatic transmission applications, compatibility with the specified automatic transmission fluid (ATF) must also be verified.

CORTECO 12010936 BA vs Other Seal Profiles

BA and BASL differ in the presence of an additional dust lip.

B1 and B2 profiles have exposed metal outer surfaces, while BA features a rubber-covered outside diameter.

These differences affect installation requirements and static sealing within the housing bore.

Radial shaft seals with identical nominal dimensions of 40x62x10 mm but different construction profiles are not automatically interchangeable.

Applications of CORTECO 12010936

Differential Assemblies

CORTECO 12010936 is listed in parts catalogues as a differential shaft seal.

In this application, the seal helps restrict lubricant leakage from the differential housing around a rotating shaft.

Automatic Transmissions

CORTECO 12010936 is also listed as a radial shaft seal for automatic transmission applications.

Correct selection requires dimensional, construction and material compatibility with the specific transmission assembly.

In particular, NBR compatibility with the specified transmission fluid, operating pressure and temperature requirements must be verified.

Other Catalogue Associations

The supplied reference numbers also include manufacturers associated with agricultural and specialist machinery, including CARRARO, GOLDONI, SAME, LAMBORGHINI, MERLO and VALTRA.

This does not establish universal compatibility with every machine manufactured by these companies.

Selection and Interchangeability

Before purchasing CORTECO 12010936, verify:

1. CORTECO product reference: 12010936.

2. Nominal shaft diameter: 40 mm.

3. Nominal housing bore diameter: 62 mm.

4. Axial seal width: 10 mm.

5. Construction profile: BA.

6. Sealing material: NBR.

7. Original equipment OEM reference number.

8. Operating medium, including gear oil or ATF where applicable.

9. Operating pressure, temperature and shaft speed.

10. Shaft surface condition and installation requirements.

Matching nominal dimensions of 40x62x10 mm do not automatically establish interchangeability between seals with different profiles or elastomer materials.

Installation and Operating Considerations

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

Inspect the shaft sealing contact area for scratches, corrosion and wear grooves.

Press the seal evenly into the housing using an installation tool suitable for its diameter and construction.

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 spring-loaded primary sealing lip faces the retained medium unless the equipment documentation specifies otherwise.

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

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