CORTECO 01033756 52x68x10/10.5 NBR BABSL Radial Shaft Seal

CORTECO 01033756 52x68x10/10.5 NBR BABSL Radial Shaft Seal

CORTECO 01033756 is an NBR radial shaft seal with exact catalogue dimensions 52x68x10/10.5 mm and manufacturer profile BABSL. CORTECO dimensional catalogue data directly associates reference 01033756 with NBR, BABSL and 52x68x10/10.5 mm. The complete profile and width geometry are important because CORTECO lists several different 52x68 mm shaft seals.

CORTECO 01033756 - Technical Characteristics

The exact technical identification is:

CORTECO 01033756 + NBR + BABSL + 52x68x10/10.5 mm

CORTECO 01033756 Dimensions

The catalogue dimensions are:

d = 52 mm - nominal shaft diameter

D = 68 mm - outside diameter

10/10.5 mm - catalogue width geometry

Complete dimensional designation:

52x68x10/10.5 mm

For this particular seal, retaining:

10/10.5 mm

is important.

The product should not be reduced to a generic:

52x68x10 mm

seal because CORTECO lists other references with 52 mm bore, 68 mm outside diameter and different profiles or width geometries.

Why the BABSL Profile Matters

The exact CORTECO/Freudenberg construction designation is:

BABSL

This profile should be retained exactly as specified by the manufacturer.

It should not be automatically converted to:

BA

BASL

TC

SC

or:

AO/TC

Different seal manufacturers use different profile designation systems, and apparently similar commercial profile names do not establish identical construction.

For technical identification, the correct entity is therefore:

CORTECO 01033756 BABSL

rather than simply:

52x68 oil seal.

NBR Material

CORTECO specifies:

NBR

for reference 01033756.

NBR stands for:

Nitrile Butadiene Rubber

and is an important part of the exact product specification.

When replacing a shaft seal, material should be checked together with dimensions and profile because identical dimensions do not necessarily mean that two seals are designed for the same operating conditions.

No generic NBR temperature range is assigned to this product because the exact operating limits depend on the specific elastomer compound and application conditions.

52x68x10 vs 52x68x10/10.5

For reference 01033756, CORTECO specifies:

52x68x10/10.5 mm

The additional:

10.5 mm

is part of the catalogue geometry and should therefore remain in the technical identification.

This is particularly useful when distinguishing 01033756 from other CORTECO seals with the same 52 mm shaft and 68 mm housing diameters.

A search based only on:

52x68x10

can return technically different CORTECO products.

CORTECO 01033756 vs Other 52x68 Seals

CORTECO catalogue data contains several different seals within the same 52x68 mm dimensional group.

Examples include:

These are separate CORTECO references with differences in profile, material or geometry.

Consequently, the dimensions:

52x68 mm

alone are insufficient for reliable replacement identification.

How a Radial Shaft Seal Works

A radial shaft seal operates between a rotating shaft and stationary housing.

The sealing interface is formed at the shaft surface, while the outside diameter of the seal is installed in the housing bore.

For 01033756, however, the exact manufacturer profile remains BABSL. The detailed lip geometry should therefore be determined from CORTECO/Freudenberg profile documentation rather than inferred from generic TC, SC or other manufacturers' seal profiles.

Selecting CORTECO 01033756

The primary parameters to verify are:

reference: 01033756

shaft diameter d = 52 mm

outside diameter D = 68 mm

width geometry = 10/10.5 mm

material = NBR

profile = BABSL

When comparing a seal from another manufacturer, additional construction details should also be checked, including lip geometry, outside-diameter design and any auxiliary sealing features required by the application.

An identical 52x68 mm dimension does not establish full technical interchangeability.

Replacement and Interchangeability

A replacement should not be selected solely from the basic dimensions.

For example, a:

52x68x10 NBR

seal may differ from CORTECO 01033756 in:

profile geometry

overall axial geometry

sealing-lip construction

outside-diameter execution

auxiliary sealing features

and potentially:

elastomer specification

The safest identification method is to retain the complete:

01033756 BABSL 52x68x10/10.5 NBR

specification.

Installation Checks

Before installing a replacement radial shaft seal, inspect the shaft sealing surface for:

wear grooves

scratches

corrosion

burrs

or other surface damage.

The housing bore and installation edges should also be checked for damage that could affect seal positioning or damage the elastomer during assembly.

For a special geometry such as 10/10.5 mm, correct axial positioning should follow the requirements of the actual assembly.

Technical Specification

FAQ

What are the dimensions of CORTECO 01033756?

The exact catalogue dimensions are 52x68x10/10.5 mm: d = 52 mm, D = 68 mm and catalogue width geometry 10/10.5 mm.

What material is CORTECO 01033756 made from?

CORTECO specifies NBR – Nitrile Butadiene Rubber.

What profile does CORTECO 01033756 use?

The exact manufacturer profile is BABSL.

Is CORTECO 01033756 a 52x68x10 oil seal?

Its basic geometry includes a 10 mm value, but the complete catalogue dimensions are 52x68x10/10.5 mm. The additional 10.5 mm value should be retained for correct identification.

Is BABSL the same as TC or SC?

It should not be treated as automatically equivalent. BABSL is the CORTECO/Freudenberg profile designation for this exact reference. Other manufacturers use different profile coding systems.

Can any 52x68x10 seal replace CORTECO 01033756?

Not automatically. Dimensions, BABSL profile, NBR material, complete 10/10.5 mm geometry and application requirements should be compared before substitution.

Are there other CORTECO seals with 52x68 mm dimensions?

Yes. CORTECO lists several separate 52x68 mm references with different profiles, materials and widths. This is why the complete 01033756 BABSL designation is important.

What application is CORTECO 01033756 intended for?

The verified CORTECO dimensional catalogue does not specify an application for reference 01033756. A specific vehicle or machine application should therefore not be assigned without additional OE or manufacturer documentation.

AI Overview

CORTECO 01033756 is an NBR radial shaft seal with exact dimensions 52x68x10/10.5 mm and CORTECO/Freudenberg profile BABSL. The complete 10/10.5 mm geometry and BABSL designation are important for replacement identification because CORTECO offers several different 52x68 mm seals with different profiles, materials and dimensions.
