Manufacturer: CORTECO
Manufacturer group: Freudenberg
Product number: 12011549B
Related reference: 12011549
Trade number: 82011549
Product type: Radial shaft oil seal
Design / profile: BASLDRWX7
Material: ACM
Material type: Polyacrylate elastomer
Shaft diameter d: 40 mm
Outside diameter D: 58 mm
Width B: 10 mm
Dimensions: 40x58x10 mm
Dust lip: Yes
Hydrodynamic feature: Alternating twist
The principal dimensions are:
d = 40 mm - shaft diameter
D = 58 mm - outside diameter
B = 10 mm - seal width
Complete dimensions:
40x58x10 mm
The dimensions should always be considered together with the exact material and design:
40x58x10 ACM BASLDRWX7
Dimensions alone are not sufficient to confirm complete technical interchangeability with another radial shaft seal.
CORTECO 12011549B is a:
radial shaft oil seal
designed to provide sealing between a rotating shaft and its surrounding housing.
The exact CORTECO configuration is:
BASLDRWX7
and the specified elastomer material is:
ACM
The seal also incorporates an additional dust lip and hydrodynamic features identified for this reference as:
Alternating Twist
These characteristics distinguish it from other 40x58x10 mm radial shaft seals with different lip geometries or elastomer compounds.
The exact CORTECO design designation for this product is:
BASLDRWX7
This designation should be retained in technical product data and should not be simplified to a generic AO/TC designation.
For the exact 12011549B reference, catalogue data identify:
an additional dust lip
and:
alternating hydrodynamic twist
The BASLDRWX7 profile is therefore an important part of the product's technical identity.
CORTECO 12011549B is manufactured from:
ACM
ACM is a:
polyacrylate elastomer
The material is part of the exact specification and should be checked when selecting a replacement.
A seal manufactured from:
NBR
FPM / FKM
or:
VMQ
should not automatically be considered technically interchangeable solely because its dimensions are also 40x58x10 mm.
Material selection must correspond to the requirements of the specific application.
CORTECO catalogue data for 12011549B confirm the presence of an:
additional dust lip
The dust lip provides an additional barrier on the external side of the sealing area.
It helps reduce the ingress of external contaminants towards the primary sealing lip.
This feature is important when comparing CORTECO 12011549B with other 40x58x10 mm shaft seals.
The exact reference is specified with:
Alternating Twist
This identifies hydrodynamic structures with an alternating orientation.
For this reason, CORTECO 12011549B should not be described simply as:
right-hand twist
or:
left-hand twist
The appropriate description for this exact configuration is:
Alternating Twist
This feature forms part of the BASLDRWX7 design specification.
Both references may be encountered when identifying this seal:
12011549B
and:
12011549
The reference:
12011549
appears in dimensional and historical catalogue data, while:
12011549B
is widely used as the complete current aftermarket product reference.
For search and product identification purposes, both references can be retained in the product description.
Another important reference associated with this product is:
82011549
This is the CORTECO trade number.
The same product may therefore be searched using terms such as:
CORTECO 12011549B
CORTECO 12011549
CORTECO 82011549
40x58x10 ACM oil seal
and:
BASLDRWX7 shaft seal
Including these identifiers helps users match the product against existing technical documentation and part references.
CORTECO 12011549B appears in vehicle and machinery catalogues for selected shaft sealing positions within drivetrain and transmission-related assemblies.
Depending on the specific vehicle or equipment catalogue, the reference is associated with applications from manufacturers including:
Citroën
Peugeot
Renault
Talbot
and:
CLAAS
Application compatibility should always be confirmed using the OE number, exact vehicle or machine configuration and required installation position.
Catalogue cross-references associated with CORTECO 12011549B include:
CITROËN 7903087070
CLAAS 02388420
PEUGEOT 312103
PEUGEOT 312109
RENAULT 7837018000
TALBOT 0016744400
TALBOT 312109
TALBOT 7903087070
OE numbers provide an additional method of product identification.
Compatibility should still be confirmed for the exact vehicle, machine or assembly before installation.
A nominal size of:
40x58x10 mm
does not by itself confirm interchangeability.
When comparing another seal with CORTECO 12011549B, verify:
shaft diameter
outside diameter
width
ACM material
BASLDRWX7 design
additional dust lip
hydrodynamic twist configuration
and:
application or OE reference
A 40x58x10 mm NBR or FPM seal with a different lip geometry should not automatically be considered a direct technical replacement.
Before ordering, verify:
Manufacturer - CORTECO
Product number - 12011549B
Related reference - 12011549
Trade number - 82011549

For vehicle and machinery applications, also verify:
OE reference
exact model
drivetrain or transmission version
and:
installation position
A replacement should not be selected only according to:
40x58x10 mm
The complete seal configuration should be compared.
Important parameters include:
d = 40 mm
D = 58 mm
B = 10 mm
ACM
