CORTECO 12018058B NBR BASL 22x47x7 Radial Shaft Seal

CORTECO 12018058B BASL is an NBR radial shaft seal measuring 22x47x7 mm. Catalogue dimensions are 22 mm inner diameter, 47 mm outer diameter and 7 mm height. The BASL design incorporates a spring-loaded primary sealing lip and an additional protective lip. This exact reference is catalogued for sealing a transfer case shaft.

CORTECO 12018058B NBR BASL 22x47x7 Radial Shaft Seal

CORTECO 12018058B BASL is a radial shaft seal (oil seal) manufactured from NBR - Nitrile Butadiene Rubber. It measures 22x47x7 mm, with a 22 mm inner diameter, 47 mm outer diameter and 7 mm height. The BASL profile combines a primary sealing lip with an additional protective lip. Catalogue data identify this exact reference as a shaft seal for a transfer case.

CORTECO 12018058B - Characteristics

CORTECO 12018058B provides dynamic sealing between a rotating shaft and stationary housing. The primary sealing lip runs against the shaft surface and controls the sealed medium.

For this specific reference, the main identification parameters are 22x47x7 mm dimensions, NBR material and BASL design. These characteristics should be considered together when identifying a replacement.

Dimensions

The catalogue dimensions of CORTECO 12018058B are:

Inner Diameter: 22 mm
Outer Diameter: 47 mm
Height: 7 mm
Dimensions: 22x47x7 mm

The three dimensions define the basic installation envelope but do not establish full interchangeability. Material and sealing design must also correspond to the requirements of the sealing position.

BASL Construction

BASL identifies a radial shaft seal construction incorporating a primary sealing lip and an additional protective lip.

The primary dynamic sealing lip is supported by a garter spring, which maintains radial contact between the sealing edge and the rotating shaft. The additional lip is positioned toward the external side and helps restrict contaminants from reaching the primary sealing zone.

The BASL profile is therefore an important part of the product specification and should not be ignored when comparing different 22x47x7 mm shaft seals.

NBR Material

CORTECO 12018058B is manufactured from NBR - Nitrile Butadiene Rubber. NBR is widely used in radial shaft sealing applications involving many mineral oils and greases.

Actual compatibility must be evaluated against the specific lubricant, operating temperature and service conditions. The NBR designation alone does not confirm compatibility with every synthetic lubricant, fuel or chemical.

Transfer Case Application

Catalogue data classify CORTECO 12018058B as a transfer case shaft seal.

This is more technically specific than describing the product simply as an automotive oil seal. When identifying the seal for a particular vehicle or transfer case, the exact reference and application data should be checked rather than relying only on the 22x47x7 mm dimensions.

12018058 and 12018058B

The product can be encountered under the references 12018058 and 12018058B in commercial and catalogue data. The complete current product reference is commonly listed as 12018058B.

Using the full 12018058B reference on the technical product page provides more precise identification while retaining 12018058 naturally in the content for catalogue and search matching.

Selection and Interchangeability

When selecting an equivalent for CORTECO 12018058B, verify:

Catalogue Reference: 12018058B
Dimensions: 22x47x7 mm
Material: NBR
Design: BASL
Product Type: Radial shaft seal
Lip Configuration: Primary sealing lip with additional protective lip
Application Requirements: Corresponding transfer case sealing position

A different 22x47x7 mm oil seal is not automatically interchangeable. Seals with different elastomers, lip configurations or application-specific designs can share identical dimensions.
