CORTECO 01031902 ACM B1BASLRS 42x62x8 Rotary Shaft Oil Seal

Product Overview

CORTECO 01031902 ACM B1BASLRS 42x62x8 is a radial shaft oil seal designed for automotive transmission and drivetrain sealing applications.

The seal has nominal dimensions of 42x62x8 mm and is manufactured from ACM (polyacrylate rubber), an elastomer widely used in automotive sealing systems exposed to oils and elevated operating temperatures.

CORTECO reference 01031902 is associated with Mercedes-Benz OEM references 0239975447, 0239978747, A0239975447 and A0239978747, making the complete reference set particularly important when identifying the correct replacement seal.

CORTECO 01031902 - 42x62x8 mm

The nominal dimensions of the seal are:

Shaft Diameter: 42 mm
Housing Diameter: 62 mm
Width: 8 mm

Although dimensions are essential for identification, an automotive oil seal should not be selected by 42x62x8 mm alone. The CORTECO reference, seal design, material and corresponding OEM number should also be verified.

This is especially important because seals with identical nominal dimensions can differ in lip geometry, material and intended application.

B1BASLRS Seal Design

The B1BASLRS designation identifies the specific CORTECO seal construction.

The sealing system incorporates a primary sealing function together with additional protection of the sealing area. This type of construction is designed to retain lubricant while helping protect the primary sealing zone against external contamination.

When replacing the original seal, the complete B1BASLRS construction should be considered rather than treating every 42x62x8 oil seal as equivalent.

ACM Polyacrylate Rubber

ACM - polyacrylate rubber is an elastomer used extensively in automotive sealing applications, particularly where resistance to lubricating oils and elevated temperatures is required.

Typical advantages of ACM include:

• good resistance to many automotive oils
• useful performance at elevated temperatures
• resistance to ageing in appropriate operating environments
• properties suitable for transmission and drivetrain sealing systems

Actual compatibility and operating limits depend on the specific ACM compound, lubricant, temperature and application conditions.

Mercedes-Benz OEM References

CORTECO 01031902 can be identified in relation to the following Mercedes-Benz references:

Mercedes-Benz 0239975447
Mercedes-Benz 0239978747
Mercedes-Benz A0239975447
Mercedes-Benz A0239978747

These references are valuable when searching for a replacement oil seal by the original vehicle or component number.

Before installation, the OEM reference and application should be verified for the specific vehicle, transmission or assembly.

Correct Replacement Selection

For replacement purposes, verify the complete identification:

CORTECO 01031902 + ACM + B1BASLRS + 42x62x8 mm + OEM reference

Matching only the three dimensions is not sufficient to confirm interchangeability.

The correct seal should correspond to the required shaft diameter, housing diameter, width, material, lip design and vehicle or transmission application.
