CORTECO 12016688B Dimensions

The principal dimensions are:

d - Nominal shaft diameter: 140 mm

D - Outside diameter: 170 mm

B1 - Height: 14.5 mm

B2 - Height: 16 mm

Complete dimensions:

140x170x14.5/16 mm

The complete dual-height designation is important when identifying this cassette seal.

The dimension should not be simplified to:

140x170x14.5 mm

or:

140x170x16 mm

because neither version describes the complete dimensional specification of CORTECO 12016688B.

NBR Nitrile Butadiene Rubber

The sealing material of CORTECO 12016688B is:

NBR - Nitrile Butadiene Rubber

NBR is one of the principal technical characteristics identifying this exact CORTECO reference.

When selecting a corresponding seal, the material should be considered together with the complete 140x170x14.5/16 mm dimensions and cassette construction.

A cassette seal of identical dimensions manufactured from FPM or another elastomer should not automatically be considered technically identical.

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

RWDR-KASSETTE Cassette Seal Design

The CORTECO Oil Seals Pocket Guide identifies the construction of 12016688B as:

RWDR-KASSETTE

This identifies the product as a cassette shaft seal.

A cassette sealing system is a more complex sealing assembly than a conventional radial shaft oil seal.

For this reason, CORTECO 12016688B should not be compared or selected solely on the basis of the 140 mm shaft diameter and 170 mm housing diameter.

The RWDR-KASSETTE construction is a principal identification criterion for this product.

CORTECO RWDR-K7

CORTECO 12016688 / 12016688B is also found under the designation:

RWDR-K7

Both terms are therefore useful for technical identification and product searches:

RWDR-KASSETTE

RWDR-K7

The primary catalogue identification can be expressed as:

CORTECO 12016688B -> NBR -> RWDR-KASSETTE -> 140x170x14.5/16 mm

RWDR-K7 should be retained as an additional technical and search identifier.

Why Is the Dimension 14.5/16 mm?

CORTECO catalogue data specifies two relevant height values:

14.5 mm

16 mm

This dual-height specification is part of the geometry of the cassette sealing system.

For identification and replacement selection, the complete dimension:

140x170x14.5/16 mm

should therefore be retained.

Simplifying the specification to only 14.5 mm or only 16 mm may result in incorrect identification of the seal.

CORTECO 12016688 vs 12016688B

The product can be found under the base / older reference:

RWDR-KASSETTE cassette construction

The 12016688 reference should be retained in the product description because it remains useful for catalogue and product searches.

CORTECO 12016688B vs Other 140x170 Shaft Seals

Matching the nominal dimensions:

140x170 mm

does not establish technical interchangeability.

When comparing another seal with CORTECO 12016688B, verify:

Inside / shaft diameter: 140 mm

Outside diameter: 170 mm

Complete height: 14.5/16 mm

Material: NBR

Cassette construction

RWDR-KASSETTE / RWDR-K7 design

OE or cross-reference number

Application requirements

A conventional 140x170 radial shaft oil seal should not automatically be considered a replacement for this cassette sealing system.

NBR vs FPM 140x170x14.5/16 Cassette Seal

CORTECO catalogue data also includes another cassette seal with the same nominal:

140x170x14.5/16 mm

dimensions but a different sealing material.

CORTECO 12016688B:

NBR

CORTECO 12016451B:

FPM

Although both references share the same nominal dimensions and RWDR-KASSETTE classification, they should not automatically be considered technically identical.

The sealing material is an important selection criterion and should be matched to the application requirements.

Selecting a Replacement for CORTECO 12016688B

When selecting a technically corresponding replacement, verify at least:

CORTECO reference: 12016688B

Base reference: 12016688

d - Nominal shaft diameter: 140 mm

D - Outside diameter: 170 mm

B1 - Height: 14.5 mm

B2 - Height: 16 mm

Material: NBR

Construction: RWDR-KASSETTE

Additional designation: RWDR-K7

EAN: 3358960144171

OE reference for the specific application

A replacement should not be selected solely on the basis of the 140x170 mm diameters.
