CORTECO 12016927 FPM BAVISLDRWX7 35x50x8 mm Oil Seal - Simmerring

1. Technical Specification

The complete designation CORTECO 12016927 FPM BAVISLDRWX7 35x50x8 mm should be retained during technical identification and procurement.

2. BAVISLDRWX7 Radial Shaft Seal Construction

CORTECO 12016927 belongs to a specialized category of radial shaft oil seals incorporating additional contamination protection and hydrodynamic sealing features.

Its primary function is to restrict lubricant leakage along a rotating shaft while helping protect the sealing interface from external contaminants.

Main Functional Components

Primary sealing lip

The primary lip maintains contact with the rotating shaft surface and helps retain lubricating oil within the mechanical assembly.

Additional dust exclusion lip

The secondary lip provides an additional barrier against dust and small external contaminants entering the primary sealing area.

Hydrodynamic sealing structures

The BAVISLDRWX7 profile is associated with an alternating twist arrangement intended to influence lubricant movement at the sealing interface.

FPM elastomer

Fluorocarbon rubber provides resistance to many lubricating oils and elevated temperatures, depending on the exact compound formulation.

Seal body

The seal body enables installation in a housing with a nominal bore diameter of 50 mm.

The precise reinforcement arrangement, spring configuration and lip geometry should be confirmed using the manufacturer's technical drawing.

3. What Does BAVISLDRWX7 Mean?

BAVISLDRWX7 is the complete construction profile designation used to identify this CORTECO shaft seal.

The profile is associated with three important characteristics:

• A defined radial shaft sealing construction.

• An additional dust exclusion lip.

• An alternating hydrodynamic twist configuration.

The term alternating twist describes a sealing lip surface arrangement intended to influence lubricant transport during shaft rotation.

The individual letters and numbers should not be interpreted independently without manufacturer documentation.

In particular, the X7 suffix does not independently establish a temperature rating, pressure limit or elastomer hardness.

The complete profile designation is essential when selecting a replacement.

4. FPM / FKM Fluorocarbon Rubber - Technical Properties

FPM and FKM are designations associated with the fluoroelastomer material family.

These elastomers are widely used in sealing applications requiring compatibility with many oils, fuels and elevated operating temperatures.

Compared with many conventional NBR compounds, FPM generally offers improved resistance to thermal ageing and ozone exposure.

Typical FPM Properties

• Good resistance to many mineral oils.

• Good compatibility with numerous lubricating greases.

• Good resistance to many petroleum-based fuels.

• High resistance to thermal ageing.

• Good resistance to ozone and atmospheric exposure.

• Low permeability to many substances.

• Limited resistance to certain ketones, amines and aggressive chemicals.

The FPM designation does not independently confirm the use of a specific branded Viton compound.

5. Chemical Resistance of FPM

This table describes general FPM material characteristics and does not represent confirmed chemical resistance testing for CORTECO 12016927.

6. Temperature Resistance

For many standard FPM compounds, an approximate operating temperature range of -20°C to +200°C is commonly referenced.

Some specialized fluoroelastomer formulations have different temperature limits, particularly at low temperatures.

This range is general material guidance and is not a confirmed operating specification for CORTECO 12016927.

In dynamic shaft sealing applications, the actual temperature at the sealing lip can exceed the bulk lubricant temperature because of friction.

Shaft speed, lubrication conditions and the operating medium must therefore be considered during selection.

7. Dimensions 35x50x8 mm Explained

The dimensions are nominal.

Correct installation also depends on shaft and housing tolerances, surface finish, installation geometry and the specified BAVISLDRWX7 profile.

An oil seal with identical dimensions but a different construction profile should not automatically be considered interchangeable.

8. Alternating Hydrodynamic Twist Design

Some radial shaft oil seals incorporate specially formed structures on the sealing lip surface.

These structures are designed to influence the movement of the thin lubricant film at the shaft contact interface.

In suitable applications, hydrodynamic features can help direct lubricant toward the oil side of the seal.

For CORTECO 12016927, the BAVISLDRWX7 profile has been associated with an alternating twist configuration.

This distinguishes it from conventional directional sealing designs intended for one specified shaft rotation direction.

However, the presence of alternating twist structures does not establish unlimited bidirectional operating capability.

Permissible rotational speed, lubrication requirements and application suitability must still be verified.

9. Automotive Catalogue Applications

CORTECO 12016927 has been associated with selected automotive drivetrain sealing applications.

These include radial shaft sealing arrangements in differential and drive axle assemblies.

Commercial catalogue references have linked this product with selected applications involving:

• Citroën

• Peugeot

• Chrysler

These associations do not confirm compatibility with every vehicle manufactured under these brands.

Correct selection requires verification of the original equipment reference, vehicle identification and the relevant mechanical assembly.

10. OE Numbers and Reference Identification

The additional references are provided for identification purposes and require confirmation against current manufacturer or OE documentation.

They should not be interpreted as unconditional interchangeability guarantees.

11. Comparison with Other 35x50x8 mm Oil Seals

Different radial shaft seals may share the same nominal dimensions while using different elastomers or construction profiles.

Although their nominal dimensions may match, these designs should not automatically be considered interchangeable.

The BAVISLDRWX7 profile has specific construction characteristics that may be essential to the original application.

12. CORTECO 12016927 Selection Criteria

Correct product selection begins with verification of the complete manufacturer reference.

The following parameters should be checked:

Hydrodynamic design

The alternating twist configuration must be suitable for the shaft rotation conditions.

Original equipment compatibility

Vehicle and assembly compatibility should be confirmed using verified OE documentation.

13. Installation and Maintenance Recommendations

Before installation, thoroughly clean the shaft and housing bore.

The sealing surface should be free from burrs, deep scratches and excessive wear.

Recommended installation practices include:

• Using appropriate installation tools.

• Protecting the sealing lip from sharp edges.

• Maintaining correct alignment during insertion.

• Avoiding deformation of the seal body.

• Following the specified installation orientation.

• Preparing the sealing lip according to the equipment manufacturer's instructions.

• Avoiding insufficient lubrication where a lubricant film is required.

Particular care should be taken to preserve the hydrodynamic sealing features during installation.

After commissioning, monitor the assembly for lubricant leakage, abnormal temperatures and shaft surface deterioration.
