CORTECO 19030263 - Dimensions

The principal dimensions are:

d - Inside diameter / shaft diameter: 38 mm

D - Outside diameter: 55 mm

B - Width: 8 mm

Dimensions: 38x55x8 mm

The first dimension represents the nominal shaft diameter, the second the outside diameter and the third the seal width.

NBR TC Double Lip Oil Seal Design

CORTECO specifies the design of this seal as:

TC

The TC construction incorporates:

primary sealing lip

garter spring

additional dust lip

The primary sealing lip forms the dynamic sealing interface with the rotating shaft.

The garter spring helps maintain radial contact between the primary sealing lip and the shaft surface.

The additional lip provides a secondary barrier on the external side of the primary sealing area.

Additional Dust Lip

The TC design incorporates an additional dust lip.

This secondary lip helps restrict dust, dirt and other external contaminants from reaching the primary sealing area.

This is an important construction characteristic when comparing CORTECO 19030263 with other 38x55x8 mm radial shaft oil seals.

Matching dimensions alone do not establish identical sealing construction.

NBR - Nitrile Butadiene Rubber

The sealing material specified for CORTECO 19030263 is:

NBR - Nitrile Butadiene Rubber

NBR is also commonly known as:

nitrile rubber

or:

Buna-N

NBR is widely used for radial shaft oil seals and other industrial sealing elements.

Depending on the exact compound, NBR is commonly compatible with many mineral oils and lubricating greases.

Exact chemical compatibility depends on the specific NBR compound, medium, additives, temperature and operating conditions.

A fixed maximum temperature, pressure or shaft speed should not be assigned without confirmation for the exact seal specification.

CORTECO 19030263 - EATON

CORTECO catalogue data associates:

19030263

with:

EATON

for the specification:

38x55x8 mm -> NBR -> TC

This provides an additional identification path when searching technical catalogues and aftermarket databases.

Compatibility with a specific EATON assembly or machine should still be confirmed against the original part specification.

CORTECO 19030263 and 19030263B

Two reference formats may be encountered in parts databases and commercial listings:

19030263

and:

19030263B

CORTECO catalogue documentation confirms:

19030263

for the 38x55x8 NBR TC seal.

The 19030263B format can also be encountered in current aftermarket listings.

Both variants can therefore be useful search terms when identifying the product, while the exact reference should always be checked against current CORTECO documentation.

TC vs SC Oil Seal

TC and SC are different radial shaft seal constructions.

TC - double lip

A spring-loaded primary sealing lip plus an additional dust lip.

SC - single lip

A spring-loaded primary sealing lip without an additional dust lip.

Therefore:

38x55x8 NBR TC

and:

38x55x8 NBR SC

may have identical principal dimensions but different sealing constructions.

They should not automatically be treated as identical products.

Why 38x55x8 Dimensions Alone Are Not Enough

Different radial shaft oil seals can share the same:

38x55x8 mm

dimensions.

However, they may differ in:

sealing material

lip configuration

dust lip

sealing geometry

application requirements

When selecting a replacement for CORTECO 19030263, compare the complete technical specification rather than the dimensions alone.

Selecting a Replacement for CORTECO 19030263

When selecting a technically corresponding replacement, check at least:

d - Shaft diameter: 38 mm

D - Outside diameter: 55 mm

B - Width: 8 mm

Material: NBR

Design: TC

Construction: Double lip

Primary sealing lip: Yes

Garter spring: Yes

Additional dust lip: Yes

Matching dimensions alone do not establish complete technical interchangeability.

The material, sealing lip configuration and requirements of the specific sealing arrangement should also be verified.
