What Does CORTECO 01019289B FPM BAVIRDX7 Mean?

CORTECO - Seal Manufacturer

CORTECO is a brand of the Freudenberg Group, supplying replacement parts and sealing solutions for automotive and industrial applications.

CORTECO rotary shaft seals are identified by their manufacturer part numbers, dimensions, elastomer materials and specific design profiles.

These characteristics are essential when selecting a replacement component for a particular transmission or rotating shaft assembly.

01019289B - Manufacturer Part Number

01019289B is the complete commercial manufacturer part number.

The shortened designation 01019289 may appear in dimensional catalogues, while 82019289 is used as an additional commercial reference.

When identifying or ordering the component, the complete manufacturer designation should be used whenever available.

35x52x7 mm - Mounting Dimensions

The dimensions specify:

• 35 mm - nominal shaft diameter.

• 52 mm - nominal housing bore diameter.

• 7 mm - nominal axial seal width.

These dimensions define the nominal installation geometry.

They do not independently establish shaft tolerances, housing tolerances, permissible shaft runout or surface finish requirements.

FPM - Fluoroelastomer Material

FPM, also referred to as FKM under another material designation system, is a fluoroelastomer used in seals requiring resistance to many oils, lubricants and elevated temperatures.

Compared with conventional NBR compounds, FPM materials generally offer improved thermal resistance and compatibility with many industrial lubricants.

However, actual suitability depends on:

• The specific lubricant or transmission fluid.

• Operating temperature.

• Chemical additives.

• Exposure duration.

• The exact elastomer formulation.

A universal operating temperature range should not be assumed for every FPM rotary shaft seal.

BAVIRDX7 - Specific Seal Design Profile

BAVIRDX7 identifies the particular construction of this CORTECO rotary shaft seal.

It must not be treated as automatically equivalent to standard BA, BASL or TC profiles.

Important characteristics to consider include:

• Main sealing lip geometry.

• Outer seating surface construction.

• Elastomer material.

• Directional sealing features.

• Shaft contact conditions.

• Installation requirements.

The complete BAVIRDX7 designation should be retained when identifying the product.

RD - Right-Hand Directional Sealing Design

The CORTECO catalogue identifies this seal with the directional designation RD.

RD indicates a right-hand directional sealing design.

Directional rotary shaft seals may incorporate specially formed sealing surfaces that assist lubricant return toward the sealed side of the assembly when the shaft rotates in the intended direction.

Consequently, shaft rotation direction is an important selection factor.

The RD designation must be interpreted according to the manufacturer's technical documentation and the specified viewing direction of the shaft.

Alternative Designations and Reference Numbers

The product may appear in catalogues and commercial listings under the following designations:

• CORTECO 01019289B

• CORTECO 01019289

• 01019289B CORTECO

• 01019289 CORTECO

• CORTECO 82019289

• CORTECO BAVIRDX7

• CORTECO 35x52x7 FPM

• Simmerring 35x52x7 RD

• CORTECO 01019289B transmission oil seal

• CORTECO 01019289B rotary shaft seal

These are identification and search variations. They must not be interpreted as independent manufacturer-approved replacement part numbers.

Original Equipment Reference Numbers

CORTECO 01019289B is associated with the following OE reference numbers.

These are catalogue cross-references.

They do not mean that the seal fits every vehicle or machine produced by the listed manufacturers.

Compatibility must be verified against the exact OE number, transmission version and equipment manufacturer's service documentation.

Construction and Operating Principle

Main Sealing Lip

The main sealing lip operates in contact with the rotating shaft surface.

Its purpose is to restrict lubricant leakage from the transmission or mechanical assembly.

Effective sealing depends on:

• Correct sealing lip contact geometry.

• Shaft surface condition.

• Suitable lubrication.

• Operating temperature.

• Rotational speed.

• Shaft alignment.

• Correct installation.

FPM Sealing Elastomer

The FPM sealing element provides resistance to many transmission oils and lubricants.

The suitability of the material must be evaluated against the actual fluid formulation, including chemical additives and operating temperature.

The FPM designation alone does not establish compatibility with every transmission fluid.

Right-Hand Directional Sealing Geometry

The RD directional design is one of the most important characteristics of this seal.

Its purpose is to support effective sealing under the intended shaft rotation conditions.

A right-hand directional seal must not automatically be replaced with an LD left-hand directional design.

Outer Seating Surface

The outer part of the seal provides secure positioning within the housing bore and contributes to static sealing between the seal and housing.

The installation method must be compatible with the BAVIRDX7 construction.

CORTECO 01019289B vs Other 35x52x7 mm Oil Seals

The dimensions 35x52x7 mm are used for rotary shaft seals with different materials, design profiles and directional characteristics.

Matching dimensions do not establish interchangeability.

CORTECO 01019289B vs CORTECO 01034939B

Both seals have dimensions of 35x52x7 mm and use FPM sealing material.

However, their design profiles and directional characteristics differ:

• CORTECO 01019289B - BAVIRDX7, RD right-hand design.

• CORTECO 01034939B - B1BAVISLRSX37, LD left-hand design.

These seals must not be considered interchangeable solely because their dimensions and elastomer materials match.

CORTECO 01019289B vs a Standard NBR Oil Seal

A standard NBR rotary shaft seal with dimensions of 35x52x7 mm may differ in:

• Thermal resistance.

• Chemical compatibility.

• Sealing lip construction.

• Directional characteristics.

• Outer seating geometry.

• Suitability for the actual operating conditions.

Dimensional compatibility alone is insufficient to confirm technical interchangeability.

Applications of CORTECO 01019289B

CORTECO 01019289B is catalogued for selected manual and automatic transmission applications.

Its OE references are associated with specific vehicles and equipment manufactured by BMW, DEUTZ-FAHR, FORD and MERCEDES-BENZ.

The seal may be used to restrict lubricant leakage along a rotating transmission shaft in an appropriately specified assembly.

Manual Transmission Shaft Sealing

In manual transmission assemblies, rotary shaft seals help retain transmission lubricant around rotating shaft interfaces.

Correct selection depends on the shaft dimensions, installation position, operating fluid and shaft rotation direction.

Automatic Transmission Shaft Sealing

Automatic transmission assemblies may also require radial rotary shaft seals.

In these applications, the exact transmission model, lubricant and manufacturer part number must be verified.

The designation CORTECO 01019289B does not establish universal compatibility with all automatic transmissions.
