Simrit Simmerring® 48x72x8 BAUSLX2 is a radial shaft seal with nominal dimensions 48x72x8 mm. The exact catalogue reference 524140 uses the 72 NBR 902 elastomer compound and the manufacturer-specific BAUSLX2 profile corresponding to DIN 3761 AS.
The catalogue specification also identifies a smooth outside surface and a pressure value of 0.05 MPa for this exact reference.

The nominal dimensions are:
d: 48 mm – shaft diameter
D: 72 mm – outside diameter
B: 8 mm – seal width
Complete dimensional designation:
48x72x8 mm
All three dimensions should be considered when identifying or selecting a replacement seal.
However, the dimensions alone do not completely identify this product because different radial shaft seal designs can share the same 48x72x8 mm dimensions.
The exact manufacturer profile for article 524140 is:
BAUSLX2.
This designation should be retained in its original form for:
technical identification
product searches
catalogue cross-referencing
and:
SEO / AI Search.
It should not be automatically replaced with generic or other manufacturers' designations such as TC, SC or AO.
The strongest product entity is:
Simrit 48x72x8 BAUSLX2 72 NBR 902 524140
This distinguishes the product from other 48x72x8 radial shaft seals.
The exact 48x72x8 BAUSLX2 reference is classified as:
DIN 3761 AS.
The AS configuration incorporates an additional protective lip on the external side of the primary sealing area.
This additional lip provides an extra barrier between the environment and the primary sealing lip.
Therefore, when evaluating an alternative seal, the complete BAUSLX2 / AS construction should be considered rather than relying solely on the nominal 48x72x8 mm dimensions.
For this product, the catalogue provides more precise information than the generic material designation:
NBR.
The exact compound is:
72 NBR 902.
This compound designation is an important part of the technical identification of article 524140.
Two seals described simply as NBR are not necessarily manufactured from the same elastomer compound.
For technical searches and product identification, the full designation:
72 NBR 902
is therefore more precise than using only:
NBR.
The exact 48x72x8 BAUSLX2 72 NBR 902 configuration is specified with a:
smooth outside surface.
This is another construction characteristic that helps distinguish article 524140 from other Simrit/Freudenberg radial shaft seals available in the same nominal dimensions.
The outside diameter should therefore not be considered only as the numerical 72 mm dimension; its construction is also relevant when evaluating replacement options.
For exact article 524140, the catalogue specifies:
0.05 MPa
which corresponds to:
0.5 bar.
This value relates to the exact 48x72x8 BAUSLX2 72 NBR 902 catalogue configuration.
It should not be interpreted in isolation as a guarantee that the seal is suitable for every application operating at this pressure.
Actual seal performance also depends on factors such as:
The complete operating conditions should therefore be evaluated when selecting the seal.
The nominal dimensions:
48x72x8 mm
are used by multiple radial shaft seal designs.
Products with the same dimensions may differ in:
profile
material compound
additional lip configuration
outside surface
pressure capability
and other technical characteristics.
For this reason, the complete identification should be:
Simrit Simmerring® 48x72x8 BAUSLX2 72 NBR 902 – Article 524140
rather than simply:
48x72x8 oil seal.
Both products have nominal dimensions 48x72x8 mm and belong to the radial shaft seal family, but they should remain separate technical and SEO entities.

Matching dimensions and the general NBR material family do not establish complete technical interchangeability.
The exact construction and application requirements should be compared before selecting a replacement.
An important product identifier is:

These identifiers help purchasing departments, maintenance specialists and workshops locate the exact product from different technical search queries.
When selecting Simrit 524140, verify:
A replacement should not be selected solely because it has the same 48x72x8 mm dimensions.
