CORTECO 19033645 NBR TB 80x105x13 mm Radial Shaft Seal

CORTECO 19033645 NBR TB 80x105x13 mm Radial Shaft Seal

CORTECO 19033645 is an NBR radial shaft seal with CORTECO profile TB and dimensions 80x105x13 mm. Correct replacement selection should consider the complete combination of the CORTECO reference, NBR material, TB profile and exact dimensions. Another 80x105x13 mm oil seal should not automatically be considered interchangeable based on dimensions alone.

Technical Data - CORTECO 19033645

CORTECO 19033645 - Precise Product Identification

The complete product identification is:

CORTECO 19033645 NBR TB 80x105x13 mm

The key identification parameters are:

CORTECO 19033645

NBR

TB

80x105x13 mm

For radial shaft seals, replacement selection should not be based on dimensions alone. Material, profile and complete sealing geometry should also be considered.

CORTECO 19033645 Dimensions

Nominal dimensions:

• inner diameter d: 80 mm
• outer diameter D: 105 mm
• width b: 13 mm

Complete dimension:

80x105x13 mm

The first dimension corresponds to the nominal shaft diameter, the second to the nominal housing diameter, and the third to the nominal seal width.

NBR - Nitrile Butadiene Rubber

CORTECO 19033645 is manufactured from:

NBR - Nitrile Butadiene Rubber

NBR is one of the most widely used elastomers in industrial sealing technology. It is commonly used in sealing components intended for operation with many mineral oils and lubricants.

Typical characteristics of NBR include:

• good resistance to many mineral oils,
• good resistance to lubricating greases,
• good mechanical properties,
• good wear characteristics in correctly designed sealing systems,
• widespread use in rotating shaft sealing applications.

Actual performance depends on the specific NBR compound, operating medium, temperature and operating conditions.

For this reason, a universal temperature range should not be assigned to CORTECO 19033645 solely from general NBR material data.

CORTECO TB Profile

The CORTECO profile designation is:

TB

The TB profile is an important part of the technical identification of CORTECO 19033645.

Individual letters in the TB designation should not automatically be decoded using another seal manufacturer's nomenclature.

Profile coding systems can differ between manufacturers.

For technical purchasing and replacement selection, retain the complete designation:

CORTECO 19033645 vs Other 80x105x13 Seals

The dimension:

80x105x13 mm

does not uniquely identify a shaft seal.

Different products with the same nominal dimensions may use different:

• elastomer materials,
• seal profiles,
• sealing lip geometries,
• external constructions,
• operating characteristics,
• intended applications.

The correct identification for this product is therefore:

80x105x13 mm + NBR + TB + CORTECO 19033645

rather than the dimensions alone.

CORTECO 19033645 vs CORTECO 19033633

These are different CORTECO references, even though both have nominal dimensions of 80x105x13 mm.

CORTECO 19033645:

NBR + TB + 80x105x13 mm

CORTECO 19033633:

ACM + SB2 + 80x105x13 mm

They therefore differ in both material and profile.

They should not automatically be treated as interchangeable simply because their nominal dimensions are identical.

Why Are Material and Profile Important?

A radial shaft seal functions as part of a complete sealing system.

Its performance can be influenced by:

• elastomer material,
• sealing element geometry,
• seal profile,
• shaft surface condition,
• operating medium,
• temperature,
• rotational speed,
• pressure,
• lubrication conditions,
• external contamination.

Two seals with identical dimensions can therefore be intended for different operating conditions.

Is Every 80x105x13 Oil Seal Interchangeable?

No.

Dimensions are only one part of the technical specification.

For CORTECO 19033645, the important combination is:

80x105x13 mm + NBR + TB

Before using another product, its material, profile, construction and intended operating conditions should be compared.

Can ACM 80x105x13 Replace NBR?

This should not be assumed.

ACM and NBR are different elastomer groups.

They can differ in:

• compatibility with operating media,
• temperature behaviour,
• mechanical characteristics,
• ageing characteristics,
• performance under specific operating conditions.

Therefore, an ACM SB2 80x105x13 mm seal should not automatically be considered a replacement for an NBR TB 80x105x13 mm seal.

Can FPM Replace NBR?

Not automatically.

FPM and NBR have different material characteristics.

Using FPM instead of NBR requires verification of:

• operating medium,
• temperature,
• seal construction,
• dynamic operating conditions,
• equipment manufacturer requirements.

A material with higher performance in one particular area is not necessarily a technically correct replacement for the original seal.

How to Select a Replacement for CORTECO 19033645

When comparing an alternative, verify:

• reference: CORTECO 19033645
• inner diameter: 80 mm
• outer diameter: 105 mm
• width: 13 mm
• material: NBR
• profile: TB
• complete sealing geometry,
• operating medium,
• operating temperature,
• shaft speed,
• lubrication conditions,
• installation arrangement.

If the exact CORTECO 19033645 reference is available, selection by the manufacturer reference is more reliable than selection solely by the 80x105x13 mm dimensions.

Installation Recommendations

Before installation, carefully clean the shaft and seal housing.

Check:

• shaft surface condition,
• housing condition,
• absence of burrs,
• absence of sharp edges,
• absence of corrosion,
• absence of excessive wear,
• correct seal orientation.

During installation, protect the sealing element from sharp edges, threads, grooves and splines.

The seal should be installed evenly using an appropriate installation tool.

Incorrect installation can damage the sealing element before the machine is returned to service.

FAQ

What are the dimensions of CORTECO 19033645?

The dimensions are 80x105x13 mm.

What material is CORTECO 19033645 made from?

The material is NBR - Nitrile Butadiene Rubber.

What profile does CORTECO 19033645 have?

The CORTECO profile designation is TB.

Is CORTECO 19033645 an oil seal?

It is a radial shaft seal and may commonly be searched as an oil seal, shaft seal, or Simmerring.

Is a standard 80x105x13 oil seal interchangeable?

Not automatically. The NBR material, TB profile and complete seal construction should also be considered.

Is CORTECO 19033633 interchangeable with CORTECO 19033645?

This should not be assumed. Both measure 80x105x13 mm, but CORTECO 19033633 uses ACM with an SB2 profile, while CORTECO 19033645 uses NBR with a TB profile.

Can ACM replace NBR?

Not automatically. Changing the elastomer requires verification against the operating medium, temperature and application requirements.

Can FPM replace NBR?

Not automatically. Material substitution requires consideration of both the operating conditions and complete seal construction.

What is the best search term for this product?

The most precise search term is CORTECO 19033645. For dimension-based searches, use CORTECO NBR TB 80x105x13.

CORTECO 19033645 - Quick Answer

CORTECO 19033645 is an NBR TB radial shaft seal measuring 80x105x13 mm. Replacement selection should consider the complete dimensions, NBR material, TB profile and sealing construction. Another 80x105x13 mm oil seal is not automatically interchangeable, particularly when it uses a different material or profile.
