CORTECO 12016448B 130x160x14.5/16 NBR RWDR-K7 Cassette Rotary Shaft Seal

CORTECO 12016448B 130x160x14.5/16 NBR RWDR-K7 Cassette Rotary Shaft Seal

CORTECO 12016448B is an RWDR-K7 cassette rotary shaft seal measuring 130x160x14.5/16 mm. The reference is associated with the Freudenberg RWDR-KASSETTE / CASS T3 design, specified with inside diameter d1 = 130 mm, outside diameter d2 = 160 mm, width b = 14.5 mm and width b1 = 16 mm. The sealing material is NBR, with Freudenberg specifying compound 75 NBR 106200 for reference 12016448.

Exact technical identification:

CORTECO 12016448B / 12016448 / 82016448 – 130x160x14.5/16 mm – NBR – RWDR-K7 – RWDR-KASSETTE – CASS T3 – cassette rotary shaft seal

CORTECO 12016448B RWDR-K7 – Technical Characteristics

The defining feature of this reference is its cassette seal construction. It is not simply a conventional open-design radial shaft seal identified only by inside diameter, outside diameter and nominal width.

Freudenberg classifies reference 12016448 within the:

Cassette & Combi Seals

product group and identifies the construction as:

RWDR-KASSETTE

and:

CASSETTE TYPE 3 / CASS T3.

For the corresponding CORTECO 12016448B reference, the technical designation:

RWDR-K7

is also used.

For accurate product identification, both descriptions are therefore relevant:

RWDR-K7 / RWDR-KASSETTE CASS T3.

CORTECO 12016448B Dimensions

The confirmed dimensions for reference 12016448 are:

For this particular construction, the shortened notation:

130x160x14.5 mm

does not communicate all of the available dimensional information.

The manufacturer specifies two axial dimensions:

b = 14.5 mm

and:

b1 = 16 mm.

For technical identification, product search and replacement comparison, the more precise notation is therefore:

130x160x14.5/16 mm.

RWDR-K7 / CASS T3 Cassette Construction

CORTECO 12016448B belongs to the cassette rotary shaft seal family.

Unlike a conventional individual radial shaft seal, a cassette seal forms a more integrated sealing arrangement. This distinction is important because two seals sharing the same 130 mm inside diameter and 160 mm outside diameter do not necessarily have the same construction.

For this exact reference, the confirmed design identifiers are:

RWDR-KASSETTE

Cassette Type 3 / CASS T3

and the CORTECO designation:

RWDR-K7.

These identifiers should be considered alongside the dimensions when selecting or cross-checking the product.

NBR Material – 75 NBR 106200

Official Freudenberg technical data for reference 12016448 specify:

75 NBR 106200.

NBR is acrylonitrile-butadiene rubber, commonly known as nitrile rubber.

The 75 in the compound designation indicates a nominal material hardness of approximately:

75 Shore A.

The confirmed NBR compound should not, however, be used by itself to assign an exact operating-temperature range, maximum shaft speed, permissible pressure or service life to this specific seal.

Those limits depend on the complete seal design and operating conditions.

12016448, 12016448B and 82016448 – Reference Identification

Several closely related numbers may appear when searching for this product.

12016448 – reference used in official Freudenberg Sealing Technologies technical data.

12016448B – corresponding CORTECO reference.

82016448 – associated CORTECO trade/product number.

Freudenberg product data for CORTECO 82016448 also associate the product with:

12016448B

and the:

Corteco

brand.

For accurate ordering, the complete CORTECO reference should therefore remain:

CORTECO 12016448B.

The related numbers 12016448 and 82016448 are valuable additional identifiers when searching technical catalogues and parts databases.

What Does RWDR-K7 Mean?

RWDR-K7 is the technical/trade designation associated with CORTECO 12016448B.

For this exact reference, it identifies a product belonging to the cassette rotary shaft seal family rather than a basic conventional radial shaft seal.

Freudenberg describes the corresponding construction as:

RWDR-KASSETTE – CASSETTE TYPE 3.

The individual characters in K7 should not be expanded into additional design claims unless a manufacturer definition for those characters is available.

What Does CASS T3 Mean?

The official Freudenberg construction designation for reference 12016448 is:

CASS T3

meaning:

CASSETTE TYPE 3.

This identifies the specific cassette-seal construction family.

Consequently, technical searches for this product may use:

RWDR-K7

RWDR-KASSETTE

or:

CASS T3.

These terms provide useful construction-level identification beyond the basic dimensions.

How Does a Cassette Rotary Shaft Seal Work?

A cassette seal is an integrated sealing assembly intended for a rotating shaft interface.

Its cassette construction distinguishes it from a conventional standalone radial shaft seal because the functional sealing components form a coordinated assembly.

For product selection, this means that the relevant characteristics include not only the nominal diameters but also:

cassette construction

axial installation dimensions

seal geometry

material

and:

exact manufacturer reference.

A conventional seal simply described as 130x160 mm should therefore not automatically be considered a substitute for CORTECO 12016448B.

CORTECO 12016448B Selection and Interchangeability

When selecting this seal or evaluating a possible equivalent, compare:

CORTECO reference – 12016448B

related reference – 12016448

trade/product number – 82016448

design – RWDR-K7 / RWDR-KASSETTE

cassette type – CASS T3

d1 = 130 mm

d2 = 160 mm

b = 14.5 mm

b1 = 16 mm

and:

NBR material.

Matching:

130 mm inside diameter

and:

160 mm outside diameter

does not by itself establish interchangeability.

This is particularly important for cassette seals because their internal geometry and sealing arrangement can differ even when the principal installation diameters are identical.

The exact product described here should be identified as:

CORTECO 12016448B – 130x160x14.5/16 mm NBR RWDR-K7 / RWDR-KASSETTE CASS T3 cassette rotary shaft seal.

Is 12016448B the Same as 12016448?

The references are directly related, but the distinction should be preserved.

12016448 appears in Freudenberg technical product data.

12016448B is the associated CORTECO reference.

For a CORTECO product listing, the safest exact identification is therefore:

CORTECO 12016448B.

The number 12016448 should remain in the description as a related technical reference rather than silently replacing the full CORTECO designation.

Is 82016448 Related to CORTECO 12016448B?

Yes.

82016448 is an associated CORTECO product/trade number, while official Freudenberg product data connect it with:

12016448B.

This makes 82016448 an important alternative catalogue and search reference.

Why Is the Size Written as 130x160x14.5/16 mm?

Because the manufacturer's technical data specify two axial dimensions:

b = 14.5 mm

and:

b1 = 16 mm.

Writing only:

130x160x14.5 mm

omits one of the confirmed dimensions.

For technical product identification, the fuller:

130x160x14.5/16 mm

notation is therefore preferable.

Can a Standard 130x160 Oil Seal Replace CORTECO 12016448B?

Not on dimensions alone.

CORTECO 12016448B is a cassette-type seal. A potential replacement should be checked for:

130 mm inside diameter

160 mm outside diameter

14.5/16 mm axial dimensions

cassette construction

seal geometry

material

and:

reference compatibility.

A conventional radial shaft seal with the same two principal diameters may have a fundamentally different construction.
