01031879 CORTECO 36x54x8 ACM B1BASW1SFDRWX1 Transmission Shaft Seal

01031879 CORTECO - Product Characteristics

CORTECO 01031879, also listed as 01031879B, is an ACM radial shaft seal catalogued for transmission shaft sealing. Its verified dimensions are 36 mm inside diameter, 54 mm outside diameter and 8 mm height. The product profile / trade designation is B1BASW1SFDRWX1 Simmerring.

The exact reference is associated with Mercedes-Benz OE numbers 0219970547 and A0219970547, making the OE number an important identification criterion when selecting this seal for a specific transmission.

Dimensions

Verified data for CORTECO 01031879 / 01031879B:

Inside Diameter: 36 mm
Outside Diameter: 54 mm
Height: 8 mm
Verified Dimensions: 36x54x8 mm
Commercial Size Also Listed: 36x54x8/12.5 mm
Material: ACM - polyacrylate rubber
Profile / Trade Number: B1BASW1SFDRWX1 Simmerring
CORTECO Reference: 01031879 / 01031879B
Additional Trade Number: 82031879
EAN: 3358960135094

The size 36x54x8/12.5 mm is also found in commercial listings. However, the additional 12.5 mm dimension should not be treated as independently verified catalog data without further CORTECO documentation.

ACM Material

01031879 CORTECO is manufactured from ACM (polyacrylate rubber).

ACM is the confirmed elastomer designation for this exact reference. A specific operating temperature range or detailed chemical-resistance specification should not, however, be assigned solely from generic ACM material properties without technical documentation for this particular seal.

This distinction is important when comparing 01031879 with another 36x54 mm shaft seal manufactured from NBR, FKM or another elastomer.

B1BASW1SFDRWX1 Profile

The exact product is identified by the profile / trade designation:

B1BASW1SFDRWX1 Simmerring

This code is an important part of the technical identity of CORTECO 01031879.

Individual elements of the B1BASW1SFDRWX1 designation should not be interpreted as a specific number of sealing lips, dust lips or structural reinforcements without CORTECO documentation explicitly defining this exact profile.

Therefore, a shaft seal with identical 36x54x8 mm dimensions but a different profile should not automatically be considered technically identical.

Alternating Twist

Catalog data for 01031879B identify the seal with an Alternating Twist characteristic.

This describes a directional feature of the sealing structure and is relevant when comparing the exact CORTECO seal with another reference.

For replacement purposes, dimensions alone are therefore insufficient. The sealing profile and directional characteristics should also be considered.

Transmission Application

CORTECO 01031879 / 01031879B is catalogued as a transmission shaft seal, with sources also identifying it in automatic transmission sealing applications.

For technical product identification, the most appropriate English terms are:

transmission shaft seal
radial shaft seal
shaft seal, transmission

A specific Mercedes-Benz vehicle or transmission should not be assigned solely from the seal dimensions. Selection should be confirmed using the OE reference and vehicle or transmission data.

Mercedes-Benz OE References

The following Mercedes-Benz OE numbers are associated with CORTECO 01031879 / 01031879B:

Mercedes-Benz: 0219970547
Mercedes-Benz: A0219970547

These OE references provide a more precise identification criterion than the dimensions alone.

When selecting the seal for a Mercedes-Benz application, the OE number and exact transmission configuration should be checked before installation.

Selection and Interchangeability

A generic 36x54x8 mm shaft seal should not automatically be treated as an equivalent to CORTECO 01031879.

For technical comparison, verify:

• 36 mm inside diameter
• 54 mm outside diameter
• 8 mm verified height
• ACM material
• B1BASW1SFDRWX1 profile
• Alternating Twist characteristic
• Mercedes-Benz OE reference
• exact installation position
• transmission compatibility

A seal with matching dimensions but a different elastomer, lip geometry or directional feature may have a different technical function.
