CORTECO 12015711 FPM B1BAVISLRDX7 55x68x8 mm - Rotary Shaft Oil Seal

CORTECO 12015711 FPM B1BAVISLRDX7 55x68x8 mm - Rotary Shaft Oil Seal

CORTECO 12015711 is a rotary shaft oil seal with dimensions 55x68x8 mm, manufactured from FPM fluoroelastomer. The full CORTECO design designation is B1BAVISLRDX7. This is a specifically defined CORTECO seal variant, so when selecting an equivalent, the dimensions, FPM material and complete seal design should all be taken into account.

Technical data - CORTECO 12015711

What does CORTECO 12015711 B1BAVISLRDX7 mean?

12015711 is the CORTECO catalogue number identifying this specific seal variant.

FPM indicates fluoroelastomer, an elastomer used for sealing applications requiring increased thermal and chemical resistance compared with standard NBR compounds.

B1BAVISLRDX7 is the complete design designation assigned to this CORTECO reference. When searching for a replacement, this designation should not be ignored or automatically replaced by a generic seal designation such as TC or AO.

55x68x8 mm defines the principal installation dimensions:

• 55 mm - inside diameter

• 68 mm - outside diameter

• 8 mm - width

FPM fluoroelastomer

CORTECO 12015711 is manufactured from FPM fluoroelastomer. The elastomer is one of the key parameters determining the operating properties of a rotary shaft seal.

FPM offers good resistance to elevated temperatures, mineral oils, fuels and many chemical media. It is therefore widely used for demanding sealing applications where the properties of standard NBR compounds may not be sufficient.

When replacing CORTECO 12015711, the material should be treated as an important selection criterion. An NBR oil seal with the same 55x68x8 mm dimensions should not automatically be considered an equivalent replacement for the FPM version.

B1BAVISLRDX7 design

The complete designation B1BAVISLRDX7 identifies the specific CORTECO seal design used for part number 12015711.

This is important when selecting a replacement because different rotary shaft seals can have identical 55x68x8 mm installation dimensions while differing in elastomer, sealing lip geometry and other construction details.

For accurate product identification, the complete specification should therefore be used:

CORTECO 12015711 - FPM - B1BAVISLRDX7 - 55x68x8 mm

CORTECO 12015711 vs other 55x68x8 mm oil seals

Dimensions alone are not sufficient to confirm full interchangeability.

Before replacing CORTECO 12015711 with another 55x68x8 mm seal, verify:

• 55 mm shaft diameter

• 68 mm housing bore

• 8 mm seal width

• FPM material

• seal design

• sealing lip geometry

• operating conditions

• shaft rotation direction if relevant to the seal design

Two rotary shaft seals with identical dimensions may have different construction and operating characteristics and therefore should not automatically be considered interchangeable.

• 55x68x8 FPM oil seal CORTECO

Selecting a replacement for CORTECO 12015711

When replacing this seal, first compare the 12015711 part number and the complete B1BAVISLRDX7 design designation.

If identification is based on the removed seal, check all markings on its surface and confirm the shaft diameter, housing bore and seal width.

When selecting an alternative based on the 55x68x8 mm dimensions, the material and seal construction must also be verified. Identical dimensions alone do not guarantee identical operating characteristics or complete interchangeability.

Installation

Before installation, clean the shaft and housing bore and inspect the surface that contacts the sealing lip. Scratches, corrosion, excessive wear or a pronounced groove on the shaft may affect the performance of the new seal.

During installation, protect the sealing lip against cutting, folding or other mechanical damage. Installation force should be applied evenly to prevent deformation of the seal.

FAQ

What are the dimensions of CORTECO 12015711?

CORTECO 12015711 has dimensions of 55x68x8 mm: 55 mm inside diameter, 68 mm outside diameter and 8 mm width.

What material is CORTECO 12015711 made from?

The seal is manufactured from FPM fluoroelastomer.

What is the full design designation of CORTECO 12015711?

The full design designation is B1BAVISLRDX7.

Is CORTECO 12015711 a Simmerring?

Yes. CORTECO 12015711 is a rotary shaft oil seal, a product type commonly referred to as a Simmerring.

Can any 55x68x8 mm oil seal replace CORTECO 12015711?

Not automatically. In addition to the dimensions, the FPM material, seal design and requirements of the specific application must be considered.

Can an NBR 55x68x8 mm seal replace CORTECO 12015711 FPM?

Not automatically. NBR and FPM are different elastomers with different operating characteristics. The sealing material must be suitable for the operating temperature, medium and application conditions.

What should be checked before ordering CORTECO 12015711?

The most important identification parameters are the 12015711 catalogue number, B1BAVISLRDX7 design, FPM material and 55x68x8 mm dimensions.
