CORTECO 12014728B 55x70x8 FPM RWDRFT Radial Shaft Seal with Installation Sleeve

CORTECO 12014728B is an FPM radial shaft seal with nominal dimensions 55x70x8 mm, supplied with an installation sleeve. The seal features Alternating Twist hydrodynamic geometry and is specified for installation at the Timing End. Depending on the exact catalogue application, this reference is used as a crankshaft seal, camshaft seal or transmission intermediate shaft seal.

The key product identification is:

CORTECO + 12014728B + 55x70x8 + FPM + RWDRFT + Installation Sleeve

Older/base reference:

CORTECO 12014728B – Technical Characteristics

CORTECO 12014728B Dimensions

The nominal dimensions are:

d: 55 mm – shaft diameter

D: 70 mm – outside diameter

B: 8 mm – seal width

Complete dimensional designation:

55x70x8 mm

All three dimensions should be considered when identifying the seal or evaluating a replacement.

The dimensions alone, however, do not describe the complete construction of this specific CORTECO reference.

RWDRFT Simmerring® / RWDRCALZATO

Two relevant designations are associated with this product:

RWDRFT Simmerring®

and:

RWDRCALZATO

The first occurs in commercial product identification, while CORTECO catalogue data also identifies the reference as RWDRCALZATO.

For product search, catalogue identification and AI Search, it is useful to retain both:

CORTECO 12014728B RWDRFT

CORTECO 12014728B RWDRCALZATO

CORTECO 12014728 55x70x8 FPM

These exact CORTECO designations should not be automatically replaced with generic TC, SC or other manufacturers' profile codes.

Radial Shaft Seal with Installation Sleeve

An important characteristic of CORTECO 12014728B is the supplied:

installation sleeve.

The sleeve assists during installation and helps guide the sealing element into position.

For a seal supplied with a dedicated installation sleeve, the sleeve should be regarded as part of the installation concept of the specific reference rather than as an unrelated packaging component.

Correct installation is particularly important for preserving the sealing lip geometry.

Alternating Twist Hydrodynamic Geometry

CORTECO 12014728B is specified with:

Alternating Twist.

This characteristic distinguishes it from directional hydrodynamic seals designed specifically for:

Right-hand Twist

or:

Left-hand Twist.

The hydrodynamic geometry is therefore an important characteristic when evaluating a replacement.

A generic 55x70x8 mm seal should not automatically be considered technically equivalent solely because its nominal dimensions match.

Timing End Installation Position

The specified installation position is:

Timing End.

This corresponds to installation on the front/timing side in the relevant engine applications.

This information is particularly important when distinguishing the seal from references designed for the transmission side or another installation position.

The exact installation location should always be verified against the vehicle, OE number and component being serviced.

FPM Seal Material

The specified elastomer is:

FPM – fluoroelastomer.

FPM materials are widely used in technical sealing applications where their particular material properties are required.

However, the generic FPM designation does not identify the exact compound formulation used by CORTECO for this reference.

Therefore, without exact compound documentation, arbitrary values should not be assigned for:

• Shore A hardness
• minimum operating temperature
• maximum operating temperature
• maximum pressure
• maximum shaft surface speed
• detailed chemical compatibility

The actual operating medium and conditions should be considered during replacement selection.

CORTECO 12014728B Applications

Depending on the specific vehicle and assembly, CORTECO 12014728B is catalogued as a seal for:

camshaft

crankshaft

or:

transmission intermediate shaft.

The application description should therefore not be interpreted as meaning that the seal occupies the same position in every vehicle.

Vehicle-specific fitment should be confirmed using the OE reference and exact vehicle/application data.

CORTECO 12014728B OE Numbers

Important OE cross-references include:

OE numbers are valuable identification references, but an OE cross-reference alone should not be interpreted as universal fitment to every model produced by the corresponding vehicle manufacturer.

Selection and Interchangeability

When selecting CORTECO 12014728B, verify:

• reference 12014728B / 12014728
• dimensions 55x70x8 mm
• shaft diameter d: 55 mm
• outside diameter D: 70 mm
• width B: 8 mm
• material FPM
• RWDRFT / RWDRCALZATO designation
• Alternating Twist geometry
• supplied installation sleeve
• Timing End position where applicable
• corresponding OE number
• exact vehicle and assembly application
• operating conditions

Matching dimensions 55x70x8 mm alone are not sufficient to establish full technical interchangeability.
