CORTECO 12016688B 140x170x14.5/16 mm NBR - Cassette Oil Seal RWDR-K7

CORTECO 12016688B 140x170x14.5/16 mm NBR - Cassette Oil Seal RWDR-K7

CORTECO 12016688B is an NBR cassette-type radial shaft seal, classified as RWDR-KASSETTE / RWDR-K7, with dimensions 140x170x14.5/16 mm. The nominal shaft diameter is 140 mm, the outside diameter is 170 mm, and the cassette design has relevant heights of 14.5 mm and 16 mm. The product is also associated with the base CORTECO reference 12016688.

CORTECO 12016688B - product characteristics

CORTECO 12016688B belongs to the group of cassette-type radial shaft seals designed for demanding mechanical assemblies.

Its construction is identified as RWDR-KASSETTE, while RWDR-K7 is also used as a technical type designation for this reference.

Unlike a conventional single radial shaft seal, a cassette seal is a more complex sealing assembly. For this reason, selecting an equivalent solely on the basis of shaft diameter and outside diameter is not sufficient.

The key identification parameters for CORTECO 12016688B are:

• CORTECO reference 12016688B
• dimensions 140x170x14.5/16 mm
• NBR sealing material
• RWDR-KASSETTE construction
• RWDR-K7 type designation

Technical data

What does CORTECO 12016688B mean?

CORTECO - the manufacturer of the sealing product.

12016688B - the full product reference used to identify this specific CORTECO seal.

12016688 - the base reference also encountered in parts catalogues and product databases.

140x170x14.5/16 mm - the complete dimensional designation: 140 mm nominal shaft diameter, 170 mm outside diameter and two relevant construction heights of 14.5 mm and 16 mm.

NBR - nitrile rubber, the elastomer used for the sealing element of this version.

RWDR-KASSETTE - the catalogue description identifying the product as a cassette-type radial shaft seal.

RWDR-K7 - an additional construction/type designation associated with this reference.

The letters and numbers in 12016688B should be treated as an integral CORTECO product reference. The final letter B should not be independently interpreted as a universal material or construction suffix without specific CORTECO documentation.

Why are the dimensions 140x170x14.5/16 mm?

The complete dimensions of CORTECO 12016688B include two height values: 14.5 mm and 16 mm.

This is not an error or two alternative measurements of the same dimension. It reflects the geometry of the cassette seal construction.

For accurate product identification, the complete dimensional designation should therefore be retained:

140x170x14.5/16 mm

It should not be simplified to 140x170x14.5 mm or 140x170x16 mm when identifying this specific product.

RWDR-KASSETTE / RWDR-K7 construction

CORTECO 12016688B is a cassette-type radial shaft seal. This construction is more complex than a conventional single radial shaft sealing ring.

When identifying this seal, it is therefore necessary to consider not only:

• 140 mm nominal shaft diameter
• 170 mm outside diameter

but also:

• 14.5/16 mm construction height
• cassette-type design
• NBR material
• complete CORTECO reference
• OE reference applicable to the particular assembly

A conventional 140x170 mm radial shaft seal should not automatically be considered interchangeable with CORTECO 12016688B.

NBR sealing material

CORTECO 12016688B uses NBR, or nitrile rubber, as its sealing elastomer.

NBR is widely used in sealing technology and is generally suitable for contact with many mineral oils and greases. Actual compatibility must nevertheless be evaluated according to the specific lubricant or medium, operating temperature, chemical additives and application conditions.

The NBR material is an important part of the identification of this particular SKU. A seal made from another elastomer should not automatically be considered equivalent merely because its nominal dimensions are identical.

Alternative designations and search references

The product may be encountered or searched for using the following references:

• CORTECO 12016688B
• 12016688B CORTECO
• CORTECO 12016688
• 12016688 CORTECO
• CORTECO 12016688B 140x170x14.5/16
• CORTECO 12016688 RWDR-K7
• 12016688B RWDR-KASSETTE
• RWDR-K7 140x170x14.5/16 NBR

The base reference 12016688 can be useful when searching older catalogues and parts databases, while 12016688B should be retained as the complete product designation.

OE and cross-reference numbers

The following references are associated with CORTECO 12016688B:

Caterpillar reference 604656 is also encountered in cross-reference catalogues.

OE and cross-reference numbers are valuable product identification data, but they should not be the sole basis for replacement selection. Compatibility should be verified against the specific machine, axle or mechanical assembly and the complete OE reference.

CORTECO 12016688B vs a standard 140x170 mm oil seal

Identical nominal diameters of 140 mm and 170 mm do not automatically mean that two seals are interchangeable.

CORTECO 12016688B has:

• RWDR-KASSETTE construction
• RWDR-K7 type designation
• NBR sealing material
• 14.5/16 mm height
• specific cassette geometry

A conventional 140x170 mm radial shaft seal may differ in construction, width, sealing interfaces and operating principle.

A replacement should therefore correspond to the complete technical specification rather than only the two principal diameters.

Selecting a replacement for CORTECO 12016688B

Before selecting an alternative seal, verify:

1. CORTECO reference 12016688B or base reference 12016688.
2. OE number of the removed seal.
3. Nominal shaft diameter of 140 mm.
4. Outside diameter of 170 mm.
5. Complete height of 14.5/16 mm.
6. RWDR-KASSETTE / RWDR-K7 construction.
7. NBR sealing material.
8. Geometry and interaction between the seal, shaft and housing.
9. Operating medium and working conditions.
10. Compatibility with the specific axle, transmission or mechanical assembly.

For cassette seals in particular, matching nominal dimensions alone does not confirm complete interchangeability.

Applications and OE identification

CORTECO 12016688 / 12016688B is catalogued with DANA-related applications and cross-references.

Additional cross-reference data links this seal with CATERPILLAR, DANA and VALTRA part numbers.

This does not mean that CORTECO 12016688B fits every machine or assembly produced by these manufacturers. Compatibility should always be confirmed using the OE number and the identification data of the specific axle, transmission or other mechanical assembly.

Installation of CORTECO 12016688B

Before installation, carefully clean the mating surfaces and inspect the shaft and housing. Dirt, corrosion, burrs or surface damage can adversely affect sealing performance and service life.

During installation:

• use a suitable installation tool that applies force evenly
• avoid direct impact on sealing components
• do not deform the cassette assembly
• maintain the specified installation position and depth
• follow the installation requirements of the equipment or assembly manufacturer

Before fitting the new seal, compare it with the removed component in terms of reference number, dimensions and geometry.
