CORTECO 12010753 FPM BASLRSX7 133.35x158.75x12.63 mm

CORTECO 12010753 FPM BASLRSX7 133.35x158.75x12.63 mm - Crankshaft Seal

CORTECO 12010753 FPM BASLRSX7 133.35x158.75x12.63 mm is a radial crankshaft seal, also catalogued as CORTECO 12010753B with trade number 82010753. It is manufactured from FPM fluoroelastomer and uses the CORTECO BASLRSX7 profile. This version has a left-hand directional sealing structure and an additional dust lip and is catalogued for installation on the transmission side of the crankshaft.

CORTECO 12010753 - Technical Data

What Does CORTECO 12010753 FPM BASLRSX7 Mean?

The complete designation provides considerably more information than the dimensions alone.

CORTECO - manufacturer and brand.

12010753 - product reference.

12010753B - reference found in current parts catalogues.

82010753 - CORTECO trade number associated with this product.

FPM - fluoroelastomer used as the sealing material.

BASLRSX7 - CORTECO profile designation for this specific seal construction.

133.35x158.75x12.63 mm - nominal seal dimensions.

Two additional characteristics are particularly important for identification: the left-hand directional structure and the additional dust lip.

CORTECO 12010753 Dimensions

The exact nominal dimensions are:

133.35x158.75x12.63 mm

where:

133.35 mm - inside diameter

158.75 mm - outside diameter

12.63 mm - width

These precise decimal dimensions should be retained when identifying or comparing the seal.

Some catalogues may display rounded dimensions such as 133.4x158.8x12.6 mm. For accurate dimensional identification, however, the more precise designation is:

133.35x158.75x12.63 mm

FPM Fluoroelastomer

CORTECO 12010753 is manufactured from FPM fluoroelastomer.

FPM is an elastomer family widely used in technical rotary shaft seals intended for appropriately selected applications involving oils, lubricants and elevated operating temperatures.

However, an exact maximum temperature, pressure or shaft speed should not be assigned to this specific seal solely on the basis of general FPM properties.

Actual operating limits depend on factors including the specific elastomer compound, operating medium, temperature, shaft surface speed, lubrication conditions and design of the complete sealing system.

CORTECO BASLRSX7 Profile

BASLRSX7 is the CORTECO profile designation assigned to this particular shaft seal.

The profile is an important identification feature because two seals with identical nominal dimensions can differ in sealing-lip geometry, directional structure, auxiliary lips and other construction details.

For CORTECO 12010753B, important confirmed construction characteristics include:

left-hand directional sealing structure

additional dust lip

The individual characters in BASLRSX7 should not automatically be interpreted according to the profile nomenclature of another seal manufacturer. Profile designation systems can be manufacturer-specific.

Left-Hand Directional Sealing Structure

CORTECO 12010753B is catalogued as a left-hand twist shaft seal.

The directional structure of the sealing surface is a technically relevant characteristic and should be considered when selecting a replacement.

A 133.35x158.75x12.63 mm seal with a right-hand, alternating or non-directional sealing structure should therefore not automatically be considered technically equivalent.

The directional configuration specified for the particular shaft and application should be retained.

Additional Dust Lip

CORTECO 12010753B is equipped with an additional dust lip.

This auxiliary lip creates an additional barrier between the surrounding environment and the primary sealing area.

Its purpose is to help limit the ingress of external contaminants towards the main sealing lip.

The presence of the dust lip should therefore be checked when comparing alternative seals, together with dimensions, material, profile and directional structure.

Crankshaft Seal - Transmission Side

CORTECO 12010753B is catalogued as a crankshaft seal for installation on the transmission side.

This corresponds to the rear area of the crankshaft, at the engine-to-transmission interface.

Because this installation position is application-specific, the product reference or OE number should be verified before installation.

The seal should not be selected solely on the basis of the 133.35 mm shaft diameter.

CORTECO 12010753 vs Other Seals with the Same Dimensions

Identical dimensions do not automatically mean complete interchangeability.

Another shaft seal may also measure:

133.35x158.75x12.63 mm

but differ in:

elastomer material

seal profile

directional structure

primary sealing-lip geometry

presence or absence of a dust lip

intended application

installation position

For this reason, a replacement should be compared against the complete specification:

CORTECO 12010753B FPM BASLRSX7 133.35x158.75x12.63 mm

rather than dimensions alone.

Confirmed OE References

CORTECO 12010753B is cross-referenced in parts catalogues with OE numbers including:

How to Select CORTECO 12010753

Before ordering, verify:

• CORTECO reference 12010753 or 12010753B,
• trade number 82010753,
• OE number of the original seal where available,
• inside diameter 133.35 mm,
• outside diameter 158.75 mm,
• width 12.63 mm,
• FPM material,
• BASLRSX7 profile,
• left-hand directional structure,
• additional dust lip,
• transmission-side installation position,
• compatibility with the specific engine or assembly.

If a readable OE reference is available on the original component, it can provide more reliable identification than measurements taken from a heavily worn or deformed seal.

Can CORTECO 12010753 Be Selected by Dimensions Alone?

This is not recommended.

The dimensions 133.35x158.75x12.63 mm are important, but they do not describe all technical characteristics of the product.

CORTECO 12010753B also has a specified:

FPM material

BASLRSX7 profile

left-hand directional structure

additional dust lip

transmission-side installation position

All of these characteristics should be considered when evaluating a replacement.

Installation of CORTECO 12010753

Before installation, thoroughly clean the seal housing and the shaft surface.

The shaft surface operating against the primary sealing lip should be free from corrosion, burrs, sharp edges and deep wear grooves.

Install the seal evenly and without tilting, using a suitable installation tool.

Installation force should not be applied in a way that deforms or damages the sealing lip.

If the seal must pass over threads, keyways or sharp shaft edges, protect the sealing surface against cutting or deformation.

Because this is a directional seal, its correct installation orientation should also be confirmed before fitting.

Storage

Elastomeric shaft seals should be stored in clean conditions, preferably in their original packaging, away from direct sunlight, excessive heat and substances that could damage the elastomer.

The sealing lip should not be permanently deformed during storage, and heavy components should not be placed directly on the seal.
