CORTECO 01016891B 28x37x5 HNBR BACX7 Oil Seal

CORTECO 01016891B 28x37x5 HNBR BACX7 Oil Seal

CORTECO 01016891B is a radial shaft oil seal measuring 28x37x5 mm, manufactured from HNBR and identified by the exact CORTECO BACX7 Simmerring design.

Manufacturer: CORTECO

Manufacturer reference: 01016891B

Base reference: 01016891

Trade Number: 82016891

Exact design designation: BACX7 Simmerring

Dimensions: 28x37x5 mm

Material: HNBR - Hydrogenated Nitrile Butadiene Rubber

ZF OE: 0770080457

EAN: 3358960130396

The complete product identification combines the CORTECO 01016891B reference, 28x37x5 mm dimensions, HNBR material, BACX7 Simmerring design and ZF 0770080457 OE reference.

CORTECO 01016891B Dimensions

The principal dimensions are:

Inside diameter d: 28 mm

Outside diameter D: 37 mm

Width B: 5 mm

Complete dimensions: 28x37x5 mm

All three dimensions should be verified when selecting a corresponding replacement.

Matching the 28 mm inside diameter, 37 mm outside diameter and 5 mm width alone does not establish complete technical interchangeability.

BACX7 Simmerring Design

The exact CORTECO design designation for this reference is:

Design: BACX7 Simmerring

CORTECO reference: 01016891B

Dimensions: 28x37x5 mm

Material: HNBR

Trade Number: 82016891

The BACX7 designation is an important part of the technical identification of CORTECO 01016891B.

It should be retained when searching for the product, comparing possible replacements or cross-referencing the ZF OE number.

A generic oil seal with the same dimensions should not automatically be considered equivalent solely because it fits the same nominal shaft and housing diameters.

HNBR Hydrogenated Nitrile Butadiene Rubber

The sealing material of CORTECO 01016891B is:

Material: HNBR - Hydrogenated Nitrile Butadiene Rubber

Current product data identify this reference as HNBR rather than standard NBR.

HNBR is a hydrogenated nitrile elastomer and should not be treated as technically identical to conventional NBR when selecting a replacement.

Material selection should always be considered together with the exact seal design, dimensions, medium and actual operating conditions.

Specific temperature, pressure, shaft speed or hardness limits should not be assigned to this exact reference without reference-specific manufacturer data.

Is CORTECO 01016891B NBR or HNBR?

For the current product identification, the material should be specified as:

Material: HNBR

Some older CORTECO catalogue data use the material designation NEM together with the BACX7 profile. Current TecDoc product data identify the material as HNBR - Hydrogenated Nitrile Butadiene Rubber.

Therefore, the recommended current product identification is:

CORTECO 01016891B 28x37x5 HNBR BACX7

rather than:

CORTECO 01016891B 28x37x5 NBR BACX7

This distinction is important for accurate technical identification and product search.

CORTECO 01016891B Steering Gear Oil Seal

CORTECO 01016891B is catalogued for steering gear sealing applications.

Product type: Steering gear seal

CORTECO reference: 01016891B

Dimensions: 28x37x5 mm

Material: HNBR

Design: BACX7 Simmerring

ZF OE: 0770080457

Exact suitability should be confirmed using the OE reference and the specific ZF steering gear assembly.

CORTECO 01016891B ZF 0770080457

CORTECO 01016891B corresponds to:

ZF OE: 0770080457

CORTECO reference: 01016891B

Trade Number: 82016891

Dimensions: 28x37x5 mm

Material: HNBR

Design: BACX7 Simmerring

The ZF 0770080457 reference is an important cross-reference when identifying this seal for a specific ZF steering gear application.

ZF 0770080457 Oil Seal

When searching for an oil seal using the ZF OE number, the principal identification data are:

ZF OE: 0770080457

CORTECO reference: 01016891B

Dimensions: 28x37x5 mm

Material: HNBR

Design: BACX7 Simmerring

Trade Number: 82016891

EAN: 3358960130396

Using the complete set of technical identifiers helps distinguish this seal from other 28x37 mm radial shaft seals.

CORTECO 01016891B vs Standard 28x37x5 Oil Seal

A standard radial shaft oil seal measuring 28x37x5 mm should not automatically be considered equivalent to CORTECO 01016891B.

CORTECO 01016891B combines:

Dimensions: 28x37x5 mm

Material: HNBR

Design: BACX7 Simmerring

ZF OE: 0770080457

Catalogue application: Steering gear

Matching the three basic dimensions alone does not establish complete technical interchangeability.

HNBR vs NBR Oil Seal

HNBR and NBR belong to the nitrile elastomer family, but they are not the same sealing material.

CORTECO 01016891B is currently identified as:

Material: HNBR - Hydrogenated Nitrile Butadiene Rubber

A standard NBR 28x37x5 mm oil seal should therefore not automatically be treated as a material-equivalent replacement.

The required elastomer should be verified together with the exact BACX7 design and operating conditions.

BACX7 vs Standard Oil Seal Design

The exact design designation of CORTECO 01016891B is:

Design: BACX7 Simmerring

This manufacturer-specific designation should be retained when identifying the product.

A generic SC, AO/TC or another standard seal type should not automatically be considered equivalent to BACX7 solely because the nominal dimensions are the same.

How to Select a Replacement for CORTECO 01016891B

When selecting a corresponding seal, verify:

• CORTECO reference 01016891B
• dimensions 28x37x5 mm
• inside diameter 28 mm
• outside diameter 37 mm
• width 5 mm
• material HNBR
• exact design BACX7 Simmerring
• ZF OE 0770080457
• exact steering gear application

Matching the dimensions alone does not confirm complete technical interchangeability.
