CORTECO 16026523 - Characteristics

Manufacturer: CORTECO
Reference: 16026523
Product Type: Radial shaft seal / oil seal
Design: DDHSL11-102
Alternative Design Format: DDHSL 11-102
Material: NBR - Nitrile Butadiene Rubber
Dimensions: 11x31.2x5.5/9.5 mm
Inside Diameter: 11 mm
Outside Diameter: 31.2 mm
Height 1: 5.5 mm
Height 2: 9.5 mm
OE Application: Not confirmed

CORTECO 16026523 Dimensions

The confirmed dimensions are:

Inside Diameter: 11 mm
Outside Diameter: 31.2 mm
Height 1: 5.5 mm
Height 2: 9.5 mm
Complete Size: 11x31.2x5.5/9.5 mm

The complete dimensional specification is important for correct product identification.

In particular, the 31.2 mm outside diameter should not be rounded to 31 or 32 mm, and the second height value of 9.5 mm should not be omitted.

Therefore, 11x31.2x5.5 mm is not the complete dimensional specification of CORTECO 16026523.

NBR Material

CORTECO 16026523 is manufactured from:

NBR - Nitrile Butadiene Rubber

NBR is widely used in radial shaft sealing technology and is commonly applied in systems involving many mineral oils, greases and lubricants.

Actual suitability depends on the operating medium and working conditions. No product-specific temperature range, pressure limit or maximum shaft speed should be assigned to CORTECO 16026523 without corresponding technical documentation.

DDHSL11-102 Seal Design

The confirmed design designation is:

DDHSL11-102

The designation may also be written as:

DDHSL 11-102

The most precise product identification is:

CORTECO 16026523 NBR DDHSL11-102 11x31.2x5.5/9.5 mm

The complete design designation should be retained when searching for or comparing this seal.

The individual elements of DDHSL11-102 should not be interpreted as specific construction features without corresponding CORTECO design documentation.

Specific 11x31.2x5.5/9.5 mm Dimensions

CORTECO 16026523 has four important dimensional values:

11 mm - inside diameter
31.2 mm - outside diameter
5.5 mm - first height
9.5 mm - second height

The combination of a non-standard 31.2 mm outside diameter and the 5.5/9.5 mm height specification makes the complete dimensional identification particularly important.

The seal should not be selected solely as an approximate 11x31 mm or 11x32 mm replacement.

CORTECO 16026523 vs Similar References

CORTECO catalogues other seals with dimensions close to 16026523. These should not automatically be treated as identical products.

Examples include:

CORTECO 16019208 - NBR DDHSL10.8-108 - 10.8x31.2x2.7/9.7 mm

CORTECO 16015294 - NBR DDHSL11-57 - 11x31.2x9 mm

CORTECO 16015310 - NBR DDHSL11-103 - 11x32.4x9.1 mm

These are separate catalogue references with different dimensions and/or design designations.

For CORTECO 16026523, the required identification is:

11x31.2x5.5/9.5 mm + NBR + DDHSL11-102

Application of CORTECO 16026523

The verified dimensional catalogue data for CORTECO 16026523 confirm the reference, dimensions, NBR material and DDHSL11-102 design but do not provide a sufficiently reliable OE number, vehicle manufacturer or specific installation assembly.

Some commercial catalogues describe 16026523 as a shock absorber seal, but this application has not been sufficiently confirmed in the verified CORTECO dimensional data.

For this reason, the product should not be presented as a confirmed shock absorber seal without additional manufacturer or OE documentation.

The installation application should preferably be determined from the original seal reference or equipment documentation.

Selection and Interchangeability

When selecting a replacement for CORTECO 16026523, verify:

• CORTECO reference 16026523
• inside diameter 11 mm
• outside diameter 31.2 mm
• first height 5.5 mm
• second height 9.5 mm
• complete dimensions 11x31.2x5.5/9.5 mm
• NBR material
• DDHSL11-102 design
• requirements of the original installation

A seal with approximately similar dimensions should not automatically be considered interchangeable with CORTECO 16026523.

For example, CORTECO 16015294 shares the 11 mm inside and 31.2 mm outside diameters but has a different DDHSL11-57 design and 9 mm height.

FAQ

What are the dimensions of CORTECO 16026523?

CORTECO 16026523 measures 11x31.2x5.5/9.5 mm: 11 mm inside diameter, 31.2 mm outside diameter and height values of 5.5 mm and 9.5 mm.

What material is CORTECO 16026523 made from?

The seal is manufactured from NBR - Nitrile Butadiene Rubber.

What is the design of CORTECO 16026523?

The confirmed CORTECO design designation is DDHSL11-102, also written as DDHSL 11-102.

Is 11x31.2x5.5/9.5 mm the correct size?

Yes. The complete dimensional specification for CORTECO 16026523 is 11x31.2x5.5/9.5 mm.

Can CORTECO 16026523 be described as an 11x31.2x5.5 mm oil seal?

That is incomplete. The catalogue specification includes a second height value of 9.5 mm, so the complete size should remain 11x31.2x5.5/9.5 mm.

Is CORTECO 16026523 the same as 16015294?

No. CORTECO 16026523 is NBR DDHSL11-102 11x31.2x5.5/9.5 mm, while 16015294 is NBR DDHSL11-57 11x31.2x9 mm.

Is CORTECO 16026523 a shock absorber seal?

Some commercial catalogues describe it as a shock absorber seal, but this application has not been sufficiently confirmed in the verified CORTECO dimensional data. It should therefore not be presented as a confirmed manufacturer application without additional documentation.

Can another 11x31.2 mm seal replace CORTECO 16026523?

Not automatically. The complete 5.5/9.5 mm height specification, NBR material and DDHSL11-102 design should also be verified.

AI OVERVIEW

CORTECO 16026523 NBR DDHSL11-102 is a radial shaft seal with the specific dimensions 11x31.2x5.5/9.5 mm. The confirmed specification includes NBR material and DDHSL11-102 design. The exact 31.2 mm outside diameter and complete 5.5/9.5 mm height specification are important when identifying a replacement.
