CORTECO 07011558 56x72x7 NBR BASLDRWX7 Radial Shaft Seal

CORTECO 07011558 56x72x7 NBR BASLDRWX7 Radial Shaft Seal

CORTECO 07011558 is an NBR radial shaft seal with exact dimensions 56x72x7 mm and CORTECO/Freudenberg profile BASLDRWX7. The construction incorporates a dust lip and alternating twist. The reference is associated with Citroën and OE numbers 9612613U, ZC96126134 and ZC9612613U.

CORTECO 07011558 - Technical Characteristics

Complete technical identification:

CORTECO 07011558 + NBR + BASLDRWX7 + 56x72x7 mm

CORTECO 07011558 Dimensions

The exact dimensions are:

d = 56 mm - inside diameter / nominal shaft diameter

D = 72 mm - outside diameter

H = 7 mm - height

Full dimensional designation:

56x72x7 mm

These dimensions form the basic installation geometry, but they are not sufficient on their own to establish interchangeability with another 56x72x7 mm seal.

BASLDRWX7 Construction

The exact CORTECO/Freudenberg profile designation is:

BASLDRWX7

The complete profile should be retained in technical documentation, product identification and replacement searches.

It should not automatically be simplified or converted to:

BASL

BA

BABSL

TC

SC

or:

AO/TC.

For the exact 07011558/07011558B reference, two additional construction characteristics are confirmed:

dust lip

and:

alternating twist.

These features are important when comparing this product with other radial shaft seals of the same nominal dimensions.

Dust Lip

CORTECO 07011558B is specified with an:

auxiliary dust lip.

The additional lip provides a barrier on the external side of the sealing arrangement and helps limit contaminants from reaching the primary sealing area.

When selecting an alternative seal, the presence of this auxiliary lip should therefore be considered together with the basic dimensions and material.

Alternating Twist

Product data for CORTECO 07011558B specifies:

alternating twist.

This means the seal should not be classified as exclusively:

right-hand twist

or:

left-hand twist.

Directional sealing characteristics are an important part of the construction and should be checked when evaluating a technically equivalent product.

NBR Material

CORTECO specifies:

NBR - Nitrile Butadiene Rubber

for reference 07011558.

The material forms part of the exact identification:

07011558 NBR BASLDRWX7

and should be considered when comparing potential replacements.

A dimensionally identical seal made from FPM/FKM, ACM or another elastomer should not automatically be considered equivalent.

A generic NBR operating-temperature range has not been assigned to this exact reference because the permissible conditions depend on the specific CORTECO/Freudenberg compound and application.

Citroën OE Numbers

Confirmed Citroën OE references associated with CORTECO 07011558 / 07011558B are:

9612613U

ZC96126134

ZC9612613U

These OE numbers provide an additional identification path when the seal is being selected for a specific Citroën application.

The most reliable selection should combine:

CORTECO reference

OE number

dimensions

and:

seal construction.

Vehicle make alone is not sufficient to establish compatibility with every Citroën model or assembly.

CORTECO Trade No. 82011558

Product data for this seal also uses:

82011558

as the CORTECO/Freudenberg Trade No.

The following identifiers may therefore be useful when searching technical catalogues:

07011558

07011558B

82011558

They should be considered together with the exact 56x72x7 NBR BASLDRWX7 specification.

07011558 and 07011558B

Both reference forms are encountered:

CORTECO 07011558

and:

CORTECO 07011558B.

The base CORTECO dimensional catalogue uses 07011558, while current product data also uses 07011558B.

The key technical identification remains:

56x72x7 mm

NBR

BASLDRWX7

with the confirmed dust-lip and alternating-twist characteristics.

Why 56x72x7 Is Not Sufficient Identification

A generic search for:

56x72x7 oil seal

identifies only the nominal installation dimensions.

For CORTECO 07011558, the complete specification also includes:

NBR material

BASLDRWX7 profile

dust lip

alternating twist

and, where relevant:

Citroën OE identification.

Consequently, another 56x72x7 mm radial shaft seal should not automatically be considered technically interchangeable.

Selection and Interchangeability

When selecting CORTECO 07011558 or evaluating a replacement, compare:

reference 07011558 / 07011558B

d = 56 mm

D = 72 mm

H = 7 mm

NBR material

BASLDRWX7 profile

dust lip

alternating twist

and, for vehicle-specific selection:

Citroën OE number and exact installation position.

Matching dimensions alone do not establish full interchangeability.
