CORTECO 49374259 Dimensions

The principal dimensions are:

d - Inside diameter / nominal shaft diameter: 45 mm

D - Outside diameter: 75 mm

B - Height: 9 mm

Complete dimensions:

45x75x9 mm

All three dimensions should be verified when selecting a replacement.

Matching the 45 mm shaft diameter and 75 mm outside diameter alone does not establish complete technical interchangeability.

ACM Polyacrylate Rubber

The sealing material of CORTECO 49374259 is:

ACM - Polyacrylate Rubber

ACM is an elastomer used in technical sealing applications involving compatible oils and lubricants.

The sealing material is an important selection criterion alongside dimensions and seal construction.

A 45x75x9 mm seal manufactured from NBR, FPM/FKM or another elastomer should not automatically be considered technically identical to CORTECO 49374259.

Exact material compatibility depends on the medium, additives, temperature and actual operating conditions.

BASLDRWX7 Simmerring Design

The exact CORTECO design designation for reference 49374259 is:

BASLDRWX7 Simmerring

This construction incorporates an additional dust lip.

The dust lip provides an additional barrier on the external side of the primary sealing area and helps restrict external contaminants from reaching the main sealing interface.

When selecting a corresponding seal, the BASLDRWX7 construction should therefore be considered together with the 45x75x9 mm dimensions and ACM sealing material.

Additional Dust Lip

CORTECO 49374259 incorporates an additional dust lip.

This is an important construction characteristic when comparing the seal with other 45x75x9 mm radial shaft oil seals.

Matching dimensions alone do not confirm that another seal has the same lip configuration.

For a technically corresponding replacement, the presence and function of the additional dust lip should also be considered.

Alternating Twist Sealing Geometry

CORTECO 49374259 is specified with:

Swirl Type: Alternating Twist

This means the seal uses alternating directional sealing geometry rather than being identified exclusively as a right-hand or left-hand twist version.

The alternating twist characteristic is an important feature of this exact CORTECO reference.

A seal with right-hand or left-hand directional geometry should not automatically be treated as technically identical solely because its dimensions are 45x75x9 mm.

CORTECO 49374259 Differential Shaft Seal

CORTECO 49374259 is catalogued as a:

Differential shaft seal

Relevant technical and search terms include:

shaft seal, differential

differential shaft seal

radial shaft oil seal

rotary shaft seal

oil seal

The application classification provides an additional identification criterion when distinguishing CORTECO 49374259 from other radial shaft seals with similar dimensions.

CORTECO 49374259 - Mercedes-Benz A1643370359

Confirmed Mercedes-Benz OE references include:

A1643370359

1643370359

The identification path is:

Mercedes-Benz A1643370359 -> CORTECO 49374259 -> 45x75x9 mm -> ACM -> BASLDRWX7

The OE number provides an important additional criterion when selecting the correct seal for a vehicle application.

Final vehicle compatibility should be confirmed using the OE reference, vehicle specification or VIN.

Additional Reference Numbers

An additional confirmed OE reference is:

ZF 0734319730

A corresponding aftermarket reference found in parts catalogues is:

ELRING 594.220

Cross-reference numbers can assist product identification, but they should not replace verification of the complete technical specification and specific application.

CORTECO 49374259 vs Other 45x75x9 Oil Seals

The dimensions:

45x75x9 mm

alone do not establish technical interchangeability.

When comparing CORTECO 49374259 with another oil seal, verify:

Inside diameter: 45 mm

Outside diameter: 75 mm

Height: 9 mm

Material: ACM

Design: BASLDRWX7

Additional dust lip

Alternating twist geometry

Mercedes-Benz OE A1643370359

Application requirements

A seal with identical dimensions but a different material, lip configuration or directional sealing geometry should not automatically be considered a direct replacement.

Selecting a Replacement for CORTECO 49374259
