What Does 28x44x6 Mean?

The dimensions 28x44x6 mm define the three principal installation dimensions:

28 mm - inside diameter
44 mm - outside diameter
6 mm - seal width

All three dimensions must match the installation.

However, dimensions alone are not sufficient to identify this seal correctly. The SCY design, NBR material and Corteco reference 19016459 are also important selection criteria.

SCY - Corteco Seal Design

Corteco specifies the design of product 19016459 as:

SCY

This designation is an important part of the original product specification.

A generic 28x44x6 seal should therefore not automatically be considered equivalent simply because its basic dimensions are identical.

For correct identification, use the complete specification:

Corteco 19016459 / 19016459B + SCY + NBR + 28x44x6 mm

Power Steering Shaft Seal

Corteco lists reference 19016459 within its range of seals for power steering systems.

In a hydraulic steering system, sealing elements are required to retain the working fluid and prevent leakage at moving interfaces.

Correct seal selection is particularly important because the required geometry and material must correspond to the specific steering unit.

For this reason, replacement selection should consider:

Corteco reference 19016459 / 19016459B,
SCY design,
28x44x6 mm dimensions,
NBR material,
SMI-KOYO application reference.

SMI-KOYO Application Reference

For 19016459 NBR SCY 28x44x6, the Corteco catalogue specifies:

SMI-KOYO

This is a valuable identification parameter when searching for the correct seal for a corresponding power steering unit.

It should not, however, be interpreted as universal compatibility with every Koyo steering system.

The existing seal reference, dimensions and design should always be verified before installation.

NBR Nitrile Rubber

Corteco 19016459 is manufactured from NBR - Nitrile Butadiene Rubber.

NBR is widely used in technical sealing applications because of its compatibility with many mineral-oil-based fluids and lubricants.

For power steering applications, material compatibility should always be verified against the specific hydraulic fluid specified for the steering system.

The actual operating temperature, pressure and fluid composition must also be considered when selecting a replacement seal.

Why the SCY Design Matters

Seals with identical 28x44x6 mm dimensions can differ significantly in their construction.

For this product, Corteco specifies:

Reference: 19016459 / 19016459B
Design: SCY
Material: NBR
Dimensions: 28x44x6 mm
Product group: Power steering seals
Application reference: SMI-KOYO

For this reason, a standard radial shaft oil seal of the same dimensions should not automatically be treated as an equivalent replacement.

19016459 vs Generic 28x44x6 Seal

Searching only for 28x44x6 seal may return products designed for different operating conditions.

The Corteco product is more precisely identified as:

Corteco 19016459 SCY NBR 28x44x6

The SCY design and Corteco reference provide additional information beyond the three basic dimensions.

This is especially important when replacing a seal from a specific power steering assembly.

How to Select Corteco 19016459

For correct replacement identification, verify:

Manufacturer: Corteco
Reference: 19016459 / 19016459B
Inside diameter: 28 mm
Outside diameter: 44 mm
Width: 6 mm
Material: NBR
Design: SCY
Application reference: SMI-KOYO

The strongest identification is:

Corteco -> 19016459 / 19016459B -> SCY -> NBR -> 28x44x6 mm -> SMI-KOYO

Do not select a replacement based on dimensions alone.
