Complete product identification:

CORTECO -> 15020026B -> 16x26x5.2 mm -> HNBR -> BASL1RD -> Right-hand Twist

CORTECO 15020026B Dimensions

The principal dimensions are:

Inside diameter / nominal shaft diameter d: 16 mm

Outside diameter D: 26 mm

Width B: 5.2 mm

Complete dimensions: 16x26x5.2 mm

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

All three dimensions should be verified when selecting a replacement.

Matching the nominal dimensions alone does not establish complete technical interchangeability.

BASL1RD Simmerring Design

The exact CORTECO design designation for reference 15020026B is:

Design: BASL1RD Simmerring

The BASL1RD designation is an important part of the complete identification of this seal.

The product incorporates an additional dust lip and directional sealing geometry.

The exact CORTECO design should therefore be considered together with the 16x26x5.2 mm dimensions and HNBR sealing material.

A seal with the same dimensions should not automatically be considered constructionally equivalent.

Additional Dust Lip

CORTECO 15020026B incorporates an additional dust lip.

Additional dust lip: Yes

The dust lip provides an additional barrier on the external side of the primary sealing area and helps restrict external contaminants from reaching the main sealing interface.

This characteristic should be considered when comparing CORTECO 15020026B with other 16x26x5.2 mm radial shaft oil seals.

Right-hand Twist Sealing Geometry

CORTECO 15020026B is specified with directional sealing geometry.

Swirl type: Right-hand Twist

This means the seal uses right-hand directional sealing geometry.

The direction is an important construction characteristic and should be considered when selecting a corresponding replacement.

A left-hand twist seal or a seal with another directional geometry should not automatically be considered technically identical.

HNBR Sealing Material

The sealing material of CORTECO 15020026B is:

Material: HNBR - Hydrogenated Nitrile Butadiene Rubber

HNBR is a hydrogenated nitrile rubber used in technical sealing applications.

The sealing material is an important selection criterion alongside dimensions and seal construction.

A 16x26x5.2 mm oil seal manufactured from NBR, ACM, FPM/FKM or another elastomer should not automatically be considered materially equivalent to CORTECO 15020026B.

Exact compatibility depends on the specific medium, additives, temperature and actual operating conditions.

Specific maximum temperature, pressure or shaft speed values should not be assigned to this exact product without direct confirmation for CORTECO 15020026B.

Exact suitability for a specific steering unit or vehicle should be verified using the required reference and application data.

CORTECO 15020026B Reference Numbers

Manufacturer: CORTECO

Manufacturer reference: 15020026B

Base reference: 15020026

Trade Number: 82020026

Design: BASL1RD Simmerring

Dimensions: 16x26x5.2 mm

Material: HNBR

Swirl type: Right-hand Twist

Additional dust lip: Yes

These parameters should be considered together when identifying CORTECO 15020026B or selecting a corresponding replacement.

Why Does Right-hand Twist Matter?

Directional sealing geometry forms part of the construction of CORTECO 15020026B.

Swirl type: Right-hand Twist

For this reason, matching the 16x26x5.2 mm dimensions and HNBR material alone is not sufficient to establish technical equivalence.

The required sealing direction should also be verified.

CORTECO 15020026B vs Standard 16x26x5.2 Oil Seal

A standard radial shaft oil seal with nominal dimensions of 16x26x5.2 mm should not automatically be considered equivalent to CORTECO 15020026B.

CORTECO 15020026B combines:

Dimensions: 16x26x5.2 mm

Material: HNBR

Design: BASL1RD Simmerring

Additional dust lip: Yes

Swirl type: Right-hand Twist

Trade Number: 82020026

All relevant technical characteristics should therefore be verified when selecting a replacement.

HNBR vs NBR Oil Seal

HNBR and NBR are related nitrile-based elastomers, but they are not the same material.

CORTECO 15020026B material: HNBR

Standard nitrile material: NBR

A seal made from NBR should not automatically be considered materially equivalent to this CORTECO HNBR seal solely because the dimensions match.

The specified sealing material should always be checked before substitution.

How to Select a Replacement for CORTECO 15020026B

When selecting a corresponding oil seal, verify:

• CORTECO reference 15020026B
• dimensions 16x26x5.2 mm
• shaft diameter 16 mm
• outside diameter 26 mm
• width 5.2 mm
• material HNBR
• design BASL1RD Simmerring
• additional dust lip
• Right-hand Twist sealing geometry
• Trade Number 82020026
• requirements of the specific installation

Matching the 16x26x5.2 mm dimensions alone does not confirm complete technical interchangeability.

What is the complete CORTECO reference for 15020026?

The complete manufacturer reference is CORTECO 15020026B. The shorter 15020026 number can be encountered as the base reference.

What material is CORTECO 15020026B made from?

Material: HNBR - Hydrogenated Nitrile Butadiene Rubber

What design is CORTECO 15020026B?

Exact design designation: BASL1RD Simmerring

Does CORTECO 15020026B have an additional dust lip?

Yes. CORTECO 15020026B incorporates an additional dust lip.

What swirl direction does CORTECO 15020026B have?

Swirl type: Right-hand Twist

The seal therefore uses right-hand directional sealing geometry.

What is the Trade Number for CORTECO 15020026B?

Trade Number: 82020026

Is HNBR the same as NBR?

No. HNBR is Hydrogenated Nitrile Butadiene Rubber, while NBR is standard nitrile rubber. They should not be treated as identical sealing materials.

Can a standard 16x26x5.2 oil seal replace CORTECO 15020026B?

Not necessarily. Matching the 16x26x5.2 mm dimensions alone does not establish complete interchangeability. The HNBR material, BASL1RD design, additional dust lip and Right-hand Twist geometry should also be verified.

Can an NBR 16x26x5.2 oil seal replace CORTECO 15020026B?

Not automatically. CORTECO 15020026B is manufactured from HNBR, while NBR is a different elastomer specification. Matching dimensions do not establish material or technical equivalence.

Can a left-hand twist seal replace CORTECO 15020026B?

Not automatically. CORTECO 15020026B is specified as Right-hand Twist, so the required directional sealing geometry should be verified before substitution.
