CORTECO 12010750B 90x110x10 FPM BASLRSX7 Rotary Shaft Seal

CORTECO 12010750B 90x110x10 FPM BASLRSX7 Rotary Shaft Seal

CORTECO 12010750B is an FPM Simmerring® radial shaft seal with nominal dimensions 90x110x10 mm and the exact CORTECO designation BASLRSX7. The seal incorporates an auxiliary dust lip and has confirmed Left-hand Twist hydrodynamic geometry. Current catalogue data specifies installation on the transmission side.

The complete product identity is:

CORTECO 12010750B + 90x110x10 + FPM + BASLRSX7 + Left-hand Twist

Additional identifiers are 82010750 and EAN 3358960107503.

CORTECO 12010750B – Technical Characteristics

The dimensional, material, dust-lip, direction and fitting-position data are consistently reported for the current 12010750B reference.

CORTECO 12010750B Dimensions

The nominal dimensions are:

d: 90 mm – shaft diameter

D: 110 mm – outside diameter

B: 10 mm – seal width

Complete dimensional designation:

90x110x10 mm

These dimensions form only one part of the product identity. For this reference, the FPM material, BASLRSX7 construction, dust lip and Left-hand Twist are also important selection criteria.

BASLRSX7 – Exact CORTECO Profile

The exact current trade designation is:

BASLRSX7 Simmerring

This designation should be retained in the product title, specification and technical description rather than replacing it with a generic TC, AO or another cross-manufacturer profile.

A particularly important feature of this reference is the confirmed auxiliary dust lip.

For technical identification, the relevant combination is therefore:

90x110x10 + FPM + BASLRSX7 + dust lip + Left-hand Twist

Left-hand Twist – Directional Hydrodynamic Geometry

Unlike a non-directional seal where no rotation direction is specified, CORTECO 12010750B has confirmed Left-hand Twist geometry.

This is a technically significant characteristic and should be considered when selecting a replacement.

A seal having the same 90x110x10 mm dimensions but a different directional structure, or a non-directional sealing lip, should not automatically be treated as technically identical.

FPM Material

The specified elastomer is:

FPM – fluoroelastomer.

For replacement identification, FPM should be considered together with the exact dimensions and seal construction.

The available exact-reference data does not provide sufficient basis for assigning a specific:

• FPM compound designation,
• Shore A hardness,
• operating temperature range,
• maximum pressure,
• maximum shaft surface speed.

These values should therefore not be inferred from generic FPM properties.

Transmission-Side Application

Current catalogue data specifies the fitting position of CORTECO 12010750B as:

Transmission side.

In applicable vehicle configurations, the product is catalogued as a crankshaft oil seal on the transmission side.

This distinction is important because the same seal reference can appear across multiple vehicle applications. Selection should therefore be based on the exact CORTECO number or OE reference, not simply on a general vehicle or engine description.

OE References

Confirmed OE cross-references associated with CORTECO 12010750B include:

These references are useful for catalogue identification but do not mean that the seal fits every vehicle produced by the listed manufacturers.

12010750 vs 12010750B

The product may be searched using the older/base designation:

CORTECO 12010750

while current catalogue data identifies it as:

CORTECO 12010750B.

For SEO and technical search, both numbers should remain visible on the page.

The primary current product entity is:

CORTECO 12010750B 90x110x10 FPM BASLRSX7

The additional Trade No. is:

82010750

and the EAN is:

3358960107503.

Selection and Interchangeability

When selecting an alternative to CORTECO 12010750B, verify:

• reference 12010750B / 12010750
• shaft diameter d: 90 mm
• outside diameter D: 110 mm
• width B: 10 mm
• FPM material
• BASLRSX7 construction
• auxiliary dust lip
• Left-hand Twist
• transmission-side fitting position
• relevant OE reference
• actual application and operating conditions

A dimensional match of 90x110x10 mm alone is not sufficient to establish technical interchangeability.

This is especially important because the confirmed Left-hand Twist is part of the functional specification of this particular seal.
