CORTECO 49363957 96x180 FPM CSESSFT Simmerring® Crankshaft Seal with Flange

CORTECO 49363957 96x180 FPM CSESSFT Simmerring® Crankshaft Seal with Flange

CORTECO 49363957 is an FPM crankshaft radial shaft seal / Simmerring® with the original CORTECO construction designation CSESSFT. It is designed for installation on the transmission side of the crankshaft and features an integrated flange and mounting sleeve.

The primary catalogue dimensions are:

d = 96 mm

D = 180 mm

This is not a conventional three-dimension radial shaft seal. CORTECO 49363957 is a complete flanged crankshaft sealing assembly and should therefore be identified primarily by the exact 49363957 part number, CSESSFT construction and corresponding OE references.

Complete identification:

CORTECO 49363957 + 96x180 + FPM + CSESSFT + flange + mounting sleeve + transmission side

CORTECO 49363957 – Technical Characteristics

CORTECO 49363957 is a complete crankshaft sealing assembly designed for installation at the transmission end of the engine.

Key catalogue characteristics include:

FPM fluoroelastomer sealing material

CSESSFT CORTECO construction designation

96 mm inside diameter

180 mm outside diameter

with flange

with mounting sleeve

transmission-side installation

The seal is catalogued for Nissan and Renault applications.

CORTECO 49363957 Dimensions

The primary dimensional data are:

Because CORTECO 49363957 is a flanged crankshaft sealing assembly, the 201 mm value should not be interpreted in the same way as the conventional axial width of a standard radial shaft seal.

Some catalogue databases additionally list 14.6 mm as a seal-height-related dimension.

For this reason, the safest technical identification is not simply “96x180x201 oil seal”, but:

CORTECO 49363957 CSESSFT FPM

together with the corresponding OE number.

CSESSFT Construction

The exact CORTECO construction designation is:

CSESSFT

This original designation should be retained in the product name and technical description.

It should not be converted into generic TC, SC, AS or similar profile codes because these do not uniquely describe the construction of this specific CORTECO reference.

For technical and international search, the important query is:

CORTECO 49363957 CSESSFT

FPM Fluoroelastomer

The specified sealing material is:

FPM – fluoroelastomer

The material is an integral part of the CORTECO 49363957 specification and should be considered when evaluating possible replacement seals.

A product with the same basic 96 mm and 180 mm diameters but a different sealing material or construction should not automatically be considered interchangeable.

Crankshaft Seal with Flange

One of the defining features of CORTECO 49363957 is its:

flanged construction

This distinguishes the product from a conventional standalone radial shaft seal.

Because the flange forms part of the complete sealing assembly, the product should be selected according to the exact CORTECO reference and OE application rather than by the two primary diameters alone.

With Mounting Sleeve

CORTECO 49363957 is specified:

with mounting sleeve

The mounting sleeve forms part of the product configuration and is an important consideration when comparing CORTECO 49363957 with alternative products.

A replacement should correspond to the complete sealing assembly, not merely the nominal shaft diameter.

Transmission-Side Crankshaft Seal

CORTECO 49363957 is installed:

on the transmission side

Alternative international technical descriptions include:

transmission-end crankshaft seal

rear crankshaft seal

crankshaft radial shaft seal – transmission side

The fitting position is important because the crankshaft seal on the timing/front side is a different component.

Confirmed Nissan OE reference:

1227900Q0F

Catalogue relationship:

Nissan 1227900Q0F → CORTECO 49363957

When selecting the seal for a specific Nissan vehicle or engine, the OE number should be used together with the engine and vehicle configuration rather than relying solely on model-level compatibility.

CORTECO 49363957 – Renault 122977139R / 122978872R

Confirmed Renault OE references:

122977139R

Catalogue relationships:

Renault 122977139R → CORTECO 49363957

Renault 122978872R → CORTECO 49363957

These exact OE numbers are highly valuable for international B2B searches and technical replacement identification.

Replacement Selection and Interchangeability

When selecting CORTECO 49363957 or an equivalent crankshaft sealing assembly, compare the complete specification:

Manufacturer: CORTECO

Part number: 49363957

Construction: CSESSFT

Material: FPM

Inside diameter: 96 mm

Outside diameter: 180 mm

Design: with flange

Installation aid: with mounting sleeve

Fitting position: transmission side

Nissan OE: 1227900Q0F

Renault OE: 122977139R / 122978872R

The preferred identification chain is:

49363957 + CSESSFT + FPM + Nissan 1227900Q0F / Renault 122977139R / 122978872R

Matching basic dimensions alone does not establish full technical interchangeability.
