CORTECO 19016631 NBR SB2 28x40x8 mm Shaft Seal

SHORT DESCRIPTION

CORTECO 19016631 NBR SB2 is a radial shaft seal measuring 28x40x8 mm, manufactured from NBR - Nitrile Butadiene Rubber. The seal is catalogued for selected Toyota steering gear applications and corresponds to Toyota OE references 90310-28014 and 90310-28027. Toyota identifies the OE component as an oil seal for the sector shaft, with 90310-28014 superseded by 90310-28027. For correct replacement selection, verify the OE number, complete dimensions, material and SB2 design.

CORTECO 19016631 NBR SB2 28x40x8 mm Shaft Seal

CORTECO 19016631 is an NBR radial shaft seal measuring 28x40x8 mm, identified with the SB2 design designation. The seal is associated with selected Toyota steering gear applications and cross-references Toyota OE numbers 90310-28014 and 90310-28027. Toyota describes OE 90310-28014 as an oil seal for the sector shaft and lists 90310-28027 as its replacement number.

CORTECO 19016631 - Characteristics

The principal product identification is:

Manufacturer: CORTECO
Reference: 19016631
Alternative Reference: 19016631B
Seal Type / Design: SB2
Product Type: Radial shaft seal / oil seal
Material: NBR
Dimensions: 28x40x8 mm
Vehicle Manufacturer Reference: Toyota
Toyota OE: 90310-28014 / 90310-28027

Independent catalogue data for CORTECO 19016631 confirm the 28 mm inside diameter, 40 mm outside diameter, 8 mm width, NBR material and SB2 designation.

The complete identification chain is therefore:

CORTECO -> 19016631 -> NBR -> SB2 -> 28x40x8 mm -> Toyota 90310-28014 / 90310-28027

CORTECO 19016631 Dimensions

The principal dimensions are:

Inside Diameter / Shaft Diameter: 28 mm
Outside Diameter / Housing Diameter: 40 mm
Width: 8 mm
Complete Size: 28x40x8 mm

These dimensions are confirmed for CORTECO reference 19016631.

All three dimensions should be checked when identifying the replacement. A generic 28x40x8 mm shaft seal should not automatically be considered technically identical because the sealing design, elastomer and application reference may differ.

NBR Material

CORTECO 19016631 is catalogued with:

NBR - Nitrile Butadiene Rubber.

NBR is an elastomer widely used in radial shaft sealing technology, particularly where compatibility with many mineral oils and greases is required.

Material identification remains important when selecting a replacement. A shaft seal with identical 28x40x8 mm dimensions but manufactured from another elastomer should not automatically be considered equivalent to CORTECO 19016631 NBR.

The suitability of any sealing material ultimately depends on the operating medium, temperature, shaft conditions and other parameters of the actual installation.

SB2 Seal Design

The design designation associated with CORTECO 19016631 is:

SB2.

The technically useful product identification is therefore:

CORTECO 19016631 NBR SB2 28x40x8

The SB2 designation should be retained in the product specification because nominal dimensions alone do not completely identify a radial shaft seal.

When comparing another 28x40x8 mm seal, the construction should therefore be checked in addition to its dimensions and material.

Toyota Steering Gear Sector Shaft Oil Seal

The OE reference 90310-28014 is identified in Toyota parts data as:

Seal, Oil (For Sector Shaft).

This places the seal in the steering gear / sector shaft assembly for the relevant Toyota applications.

For this reason, the product can accurately be described as a:

Toyota steering gear shaft seal
Toyota sector shaft oil seal
Toyota steering gear oil seal

This is more technically precise than describing CORTECO 19016631 simply as a generic automotive oil seal.

Toyota OE 90310-28014

One of the principal OE references associated with CORTECO 19016631 is:

TOYOTA 90310-28014

The same number may also be encountered without hyphens:

9031028014

Toyota parts data describe this component as Seal, Oil (For Sector Shaft).

The OE number is particularly useful when the old seal is damaged or its dimensions and construction cannot be reliably identified from the removed component.

Toyota OE 90310-28027

The second associated Toyota OE reference is:

TOYOTA 90310-28027

also written:

9031028027

Importantly, Toyota parts data indicate that 90310-28014 was replaced by 90310-28027.

This relationship is useful for parts identification because older vehicle documentation or removed components may reference 90310-28014, while later catalogues may use 90310-28027.

CORTECO 19016631 / 19016631B is catalogued against both Toyota references.

Toyota Applications

Toyota catalogue data associate OE 90310-28014 with selected older Toyota Corolla steering gear configurations, including applications from the 1970s.

However, vehicle model and production year alone should not be used as the sole selection criterion.

Toyota vehicles can have different steering configurations depending on model code, production period and market specification. For accurate selection, preference should be given to:

Toyota OE number -> seal dimensions -> CORTECO reference -> seal design and material

A VIN or vehicle-specific parts catalogue should be used when application certainty is required.

19016631 and 19016631B

The CORTECO seal is also encountered in aftermarket catalogues under the reference:

19016631B

Catalogue cross-reference data for 19016631B associate it with Toyota OE numbers 90310-28014 and 90310-28027.

When identifying stock, packaging or supplier references, it is therefore useful to search both:

CORTECO 19016631
CORTECO 19016631B

The actual reference printed on the supplied CORTECO packaging should remain the primary identification for inventory purposes.

Selection and Interchangeability

When selecting a replacement for CORTECO 19016631, verify:

• CORTECO reference: 19016631 / 19016631B
• inside diameter: 28 mm
• outside diameter: 40 mm
• width: 8 mm
• material: NBR
• design: SB2
• Toyota OE: 90310-28014 or 90310-28027
• required installation position
• operating medium and conditions

A generic 28x40x8 mm oil seal is not automatically equivalent to CORTECO 19016631.

Likewise, dimensional compatibility alone does not prove that a seal has the same lip geometry, material or application specification.
