CORTECO 19016649 NBR SB2Y 52x65x9 mm

CORTECO 19016649 NBR SB2Y 52x65x9 mm - Daihatsu Toyota Rotary Shaft Seal

CORTECO 19016649 NBR SB2Y 52x65x9 mm is a radial rotary shaft seal used in selected Daihatsu and Toyota applications, including drivetrain, differential and axle-related sealing positions depending on the specific vehicle configuration. It is manufactured from NBR (nitrile butadiene rubber) and has a 52 mm inside diameter, 65 mm outside diameter and 9 mm width. CORTECO assigns the SB2Y profile to this specific seal. The product is also encountered as CORTECO 19016649B.

CORTECO 19016649 - Technical Data

What Does CORTECO 19016649 NBR SB2Y Mean?

The complete designation identifies a specific CORTECO rotary shaft seal.

CORTECO - manufacturer and brand specialising, among other product groups, in sealing technology.

19016649 - CORTECO reference number for this specific product.

19016649B - reference also encountered in current parts catalogues and distribution channels.

82016649 - trade number associated with this product.

NBR - nitrile butadiene rubber used as the elastomer material.

SB2Y - CORTECO profile designation assigned to this specific seal construction.

52x65x9 mm - nominal dimensions: 52 mm inside diameter, 65 mm outside diameter and 9 mm width.

The SB2Y profile is an important part of product identification. Another shaft seal with dimensions of 52x65x9 mm should not automatically be considered interchangeable with CORTECO 19016649.

CORTECO 19016649 Dimensions

The nominal dimensions are:

52x65x9 mm

where:

52 mm - inside diameter

65 mm - outside diameter

9 mm - seal width

The 52 mm inside diameter corresponds to the nominal diameter of the mating rotating component, while the 65 mm outside diameter corresponds to the nominal housing bore.

Dimensions alone are not sufficient to establish interchangeability.

The NBR material, SB2Y profile, seal construction, intended installation position and OE reference should also be considered.

NBR - Nitrile Butadiene Rubber

CORTECO specifies NBR, or nitrile butadiene rubber, for reference 19016649.

NBR is one of the most widely used elastomers in oil seals and radial rotary shaft sealing systems.

It is commonly used in sealing applications operating with compatible mineral oils, greases and other suitable lubricants.

However, the general characteristics of NBR should not be treated as the exact operating specification of this individual CORTECO product.

Actual suitability depends on the specific elastomer compound, operating medium, temperature, shaft surface speed and design of the complete sealing system.

For this reason, no unverified exact temperature, pressure or rotational speed limits are assigned to CORTECO 19016649.

CORTECO SB2Y Profile

CORTECO assigns the SB2Y profile designation to this specific product.

The profile is an important part of the technical specification and should be considered when identifying the seal or selecting an alternative.

The individual letters in SB2Y should not automatically be interpreted using the terminology of other seal manufacturers.

Seal profile designations can be manufacturer-specific and are not necessarily equivalent across different brands.

For accurate identification, compare the complete specification:

CORTECO 19016649 / 19016649B

SB2Y

NBR

52x65x9 mm

Daihatsu or Toyota OE reference

This significantly reduces the risk of selecting a dimensionally similar but technically different seal.

Construction and Operating Principle

CORTECO 19016649 is a radial rotary shaft seal designed to separate a lubricant-containing area from the external environment around a rotating drivetrain component.

The sealing lip works against the mating shaft or axle surface and forms the dynamic sealing zone.

Correct operation depends not only on the nominal dimensions but also on the condition of the mating surface, correct installation in the housing, operating lubricant and suitability of the seal construction for the application.

CORTECO 19016649 - Differential Shaft Seal

Current parts catalogues classify CORTECO 19016649B as a differential shaft seal.

Depending on the specific vehicle application, the product may also be listed in categories associated with the axle or wheel hub area.

CORTECO 19016649 should therefore not be treated simply as a universal industrial 52x65x9 mm oil seal. It is a specific automotive reference with defined Daihatsu and Toyota OE applications.

When selecting the seal for a vehicle, priority should be given to the OE number and exact drivetrain configuration.

Daihatsu and Toyota OE Numbers

The following OE references are associated with CORTECO 19016649B:

DAIHATSU 9004311250

DAIHATSU 9031152059

TOYOTA 9031152059

Reference 9031152059 is therefore associated with both Toyota and Daihatsu applications.

OE numbers provide a more precise identification point than seal dimensions or vehicle manufacturer alone.

Toyota OE 9031152059

For Toyota applications, an important OE reference associated with CORTECO 19016649B is:

TOYOTA 9031152059

This number can be used when comparing the CORTECO seal with the original Toyota component.

The OE reference is associated with axle-related sealing applications.

Before purchase, compatibility should still be confirmed for the exact vehicle model, production year and drivetrain configuration.

Daihatsu OE 9004311250 and 9031152059

For Daihatsu applications, CORTECO 19016649B is associated with:

DAIHATSU 9004311250

DAIHATSU 9031152059

If either number appears on the removed component or in the vehicle parts documentation, CORTECO 19016649 / 19016649B can be checked as the corresponding aftermarket reference.

Final compatibility should always be confirmed for the exact vehicle and installation position.

Daihatsu Applications

Parts catalogues associate CORTECO 19016649B with selected versions of vehicle families including:

Daihatsu Feroza

Daihatsu Rocky / Fourtrak

Different axle and drivetrain configurations may have been used within these model families.

This does not mean that CORTECO 19016649 fits every vehicle sold under these model names.

The OE number remains the more precise identification method.

Toyota Applications

CORTECO 19016649B is catalogued for selected versions of older Toyota vehicle families, including:

Toyota Carina

Toyota Celica

Toyota Corolla

Toyota LiteAce

Toyota Previa / Estima

Catalogue applications also include selected versions of the Toyota Corolla Coupe AE86.

Different axles, differentials and drivetrain configurations can occur within the same vehicle family.

For this reason, the product should not be selected solely according to vehicle model name. The OE reference 9031152059 provides a more precise identification point.

CORTECO 19016649 vs Other 52x65x9 mm Shaft Seals

The nominal dimensions 52x65x9 mm are not sufficient to establish interchangeability.

CORTECO 19016649 has the specific combination:

52x65x9 mm

NBR

SB2Y

Daihatsu and Toyota applications

OE 9004311250 / 9031152059

CORTECO catalogues also contain other shaft seals with the same basic 52x65x9 mm dimensions but different profiles and applications.

This demonstrates why the dimensional specification alone should not be used as the only replacement criterion.

Cross-Reference Numbers

Cross-reference catalogues associate this application with several aftermarket references.

Cross-reference numbers can be useful during product identification, but they should not be treated as independent proof of complete technical interchangeability.

Before replacing CORTECO 19016649 with another manufacturer's product, compare its complete dimensions, material, construction profile and intended application.

Selection and Interchangeability

Before purchasing or replacing CORTECO 19016649 / 19016649B, verify:

• complete CORTECO reference,
• dimensions 52x65x9 mm,
• NBR elastomer material,
• SB2Y profile,
• OE number of the original component,
• installation position,
• axle or differential configuration,
• condition of the mating shaft or axle surface,
• operating lubricant,
• requirements of the specific application.

Identical dimensions do not automatically mean complete interchangeability.

A 52x65x9 mm seal with a different profile, elastomer material or intended application may be a technically different product.

Installation of CORTECO 19016649

Before installation, carefully clean the housing bore and the mating shaft or axle surface.

The sealing lip contact area should be free from corrosion, sharp edges, burrs and deep wear grooves that could damage the seal or cause leakage.

Install the seal squarely and evenly using an installation tool suitable for its diameter and construction.

Do not apply direct impact to the elastomer sealing components.

The sealing lip should be protected against cutting, folding or deformation during installation.

Before assembly, also verify the correct orientation of the seal relative to the lubricant side.
