What Does CORTECO 01034939B FPM B1BAVISLRSX37 Mean?

CORTECO - Seal Manufacturer

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

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

These characteristics are important when selecting a replacement seal for a particular shaft assembly.

01034939B - Manufacturer Part Number

01034939B identifies a specific CORTECO rotary shaft seal.

The designation 01034939, without the final letter B, also appears in dimensional catalogue references.

When ordering or identifying the component, the complete manufacturer part number should be retained whenever it appears on the packaging or in the technical documentation.

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 specify 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, fluoroelastomers generally provide improved thermal resistance and compatibility with many industrial lubricants.

However, actual chemical compatibility depends on:

• The specific fluid.

• Operating temperature.

• Fluid concentration and additives.

• Exposure duration.

• The exact elastomer compound.

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

B1BAVISLRSX37 - Specific Seal Design Profile

B1BAVISLRSX37 identifies the particular construction of this CORTECO rotary shaft seal.

Its technical characteristics must not be inferred solely from standard BA, BASL or other commonly used oil seal profiles.

Important design considerations include:

• Main sealing lip geometry.

• Additional dust lip.

• Outer sealing surface construction.

• Elastomer material.

• Directional sealing characteristics.

• Shaft contact conditions.

The complete profile designation is essential for correct identification.

LD - Left-Hand Directional Seal

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

LD indicates a left-hand directional sealing design.

Directional shaft seals may incorporate surface features that assist lubricant return toward the sealed side of the assembly when the shaft rotates in the intended direction.

Consequently, the correct shaft rotation direction is an important selection factor.

The direction must be interpreted according to the manufacturer's 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 references:

• CORTECO 01034939B

• CORTECO 01034939

• 01034939B CORTECO

• 01034939 CORTECO

• CORTECO 82034939

• B1BAVISLRSX37

• CORTECO B1BAVISLRSX37 Simmerring

• CORTECO 35x52x7 FPM

• Simmerring 35x52x7 FPM LD

• CORTECO 01034939B rotary shaft seal

OE Reference Number

Mitsubishi MB837030.

This reference is associated with the catalogue application of the component.

Compatibility must be verified against the specific vehicle, drivetrain configuration and service documentation before installation.

Construction of CORTECO 01034939B

Main Sealing Lip

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

Its purpose is to restrict lubricant leakage from the sealed assembly.

Effective sealing depends on:

• Correct lip contact geometry.

• Shaft surface condition.

• Lubrication.

• Rotational speed.

• Operating temperature.

• Shaft alignment.

• Installation accuracy.

Additional Dust Lip

CORTECO 01034939B incorporates an additional dust lip.

The dust lip helps limit the entry of external contaminants toward the primary sealing area.

This additional protection can be beneficial in assemblies exposed to dust or other environmental contamination.

However, a dust lip does not make the seal completely waterproof or suitable for unrestricted exposure to pressurised water.

FPM Sealing Elastomer

The fluoroelastomer sealing element provides resistance to many oils and lubricants.

FPM is particularly relevant where the operating conditions require suitable chemical and thermal resistance.

Its suitability must be confirmed for the actual operating medium and temperature.

Directional Sealing Geometry

The LD directional design is an important characteristic of this product.

It should not automatically be replaced with an RD right-hand directional seal or a non-directional seal without verifying the requirements of the mechanical assembly.

CORTECO 01034939B vs Other 35x52x7 mm Oil Seals

The dimensions 35x52x7 mm are used for rotary shaft seals with different materials and construction profiles.

These seals have identical nominal mounting dimensions but differ in material and construction.

They must not automatically be considered interchangeable.

CORTECO 01034939B vs CORTECO 01019289B

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

However, they differ in their design profiles and directional characteristics.

They should not be substituted solely because their dimensions match.

CORTECO 01034939B vs a Standard NBR Oil Seal

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

• Thermal resistance.

• Chemical compatibility.

• Sealing lip geometry.

• Outer surface construction.

• Directional sealing features.

• Dust lip configuration.

Matching dimensions are not sufficient to establish technical interchangeability.

Applications of CORTECO 01034939B

CORTECO 01034939B is associated with specific Mitsubishi applications, including selected Mitsubishi 3000 GT drivetrain configurations.

The Mitsubishi OE reference MB837030 appears in replacement-part catalogues.

Before installation, verify:

• The part number of the removed seal.

• The original equipment reference.

• Vehicle or assembly configuration.

• Installation position.

• Shaft rotation direction.

• Shaft and housing dimensions.

• Sealed fluid type.

Other automotive applications must not be assumed solely from the dimensions of 35x52x7 mm.

Typical Operating Function

As a radial rotary shaft seal, this component is designed to restrict lubricant leakage along a rotating shaft.

Its additional dust lip helps reduce contamination of the primary sealing area.

The directional LD construction must correspond to the shaft rotation requirements of the assembly.

Selecting a 35x52x7 mm FPM Rotary Shaft Seal

Before selecting CORTECO 01034939B, verify:

1. Manufacturer part number 01034939B.

2. Complete profile B1BAVISLRSX37.

3. Nominal shaft diameter of 35 mm.

4. Housing bore diameter of 52 mm.

5. Seal width of 7 mm.

6. FPM elastomer material.

7. Additional dust lip.

8. LD left-hand directional design.

9. Type of sealed medium.

10. Operating temperature.

11. Shaft rotational speed.

12. Shaft surface condition.

13. Housing and shaft tolerances.

14. Installation orientation.

15. Equipment manufacturer's requirements.

For directional rotary shaft seals, the correct profile and rotation direction can be as important as dimensional compatibility.

Installation and Operating Recommendations

Shaft Preparation

The shaft surface should be clean and free from burrs, corrosion and damage in the sealing lip contact area.

Surface imperfections may increase lip wear or cause leakage.

Housing Preparation

Clean the housing bore and inspect it for dimensional accuracy and surface damage.

The seal must be installed without damaging its outer surface.

Correct Installation Orientation

Install the seal according to the technical documentation for the assembly.

For a directional design, the shaft rotation direction must be compatible with the seal construction.

Protecting the Sealing Lip

Avoid contact between the sealing lip and sharp edges, keyways or shaft grooves during installation.

Use suitable installation sleeves when necessary.

Lubrication

Lubrication of the sealing lip must follow the equipment manufacturer's instructions and the requirements of the elastomer material.

Operation under unsuitable dry-running conditions should be avoided.

Storage

Store the seal in a clean, dry environment away from excessive heat, direct sunlight and substances that may damage the elastomer.

Avoid deforming the sealing lip during storage.
