CORTECO 12000756B 40x52x8 ACM BARS Oil Seal

CORTECO 12000756B 40x52x8 ACM BARS Oil Seal

CORTECO 12000756B is a radial shaft oil seal measuring 40x52x8 mm and manufactured from ACM.

Manufacturer: CORTECO

Manufacturer reference: 12000756B

Base reference: 12000756

Trade Number: 82000756

Exact design designation: BARS Simmerring

Material: ACM - Polyacrylate Rubber

Dimensions: 40x52x8 mm

Swirl Type: Left-hand Twist

RUGGERINI OE: 05451

EAN: 3358960463203

The complete product identification combines the CORTECO 12000756B reference, 40x52x8 mm dimensions, ACM material, BARS Simmerring design and left-hand twist sealing geometry.

CORTECO 12000756B Dimensions

The principal dimensions are:

Inside diameter / nominal shaft diameter d: 40 mm

Outside diameter D: 52 mm

Width B: 8 mm

Complete dimensions: 40x52x8 mm

The first dimension corresponds to the nominal shaft diameter, the second to the outside diameter of the seal and the third to its width.

All three dimensions should be verified when selecting a replacement.

The sealing material, exact design and directional sealing geometry should also be considered.

Matching the 40x52x8 mm dimensions alone does not establish complete technical interchangeability.

BARS Simmerring Design

The exact CORTECO design designation for this oil seal is:

Design: BARS Simmerring

CORTECO reference: 12000756B

BARS is the specific CORTECO design designation and forms an important part of the complete product identification.

When selecting a replacement, the BARS designation should be considered together with the dimensions, ACM material and directional sealing geometry.

The exact BARS design should not be automatically replaced with a generic AO/TC, SC or another oil seal designation solely because the dimensions are identical.

Left-hand Twist Sealing Geometry

CORTECO 12000756B uses directional sealing geometry.

Swirl Type: Left-hand Twist

Direction: Left-hand

Directional sealing geometry is an important construction characteristic when comparing this product with other 40x52x8 mm radial shaft oil seals.

An oil seal with the same nominal dimensions but a different directional sealing geometry should not automatically be considered technically equivalent.

The required direction should therefore be verified when selecting a replacement.

ACM Polyacrylate Rubber

The sealing material of CORTECO 12000756B is:

Material: ACM - Polyacrylate Rubber

ACM is an elastomer used in technical radial shaft sealing applications.

The material is an important identification and selection criterion alongside the dimensions and seal construction.

A 40x52x8 mm oil seal manufactured from NBR, FPM/FKM, HNBR or another elastomer should not automatically be considered materially equivalent to CORTECO 12000756B.

Exact material compatibility depends on the medium, additives, temperature and actual operating conditions.

Specific maximum temperature, pressure, shaft speed or hardness values should not be assigned to this exact reference without direct confirmation for CORTECO 12000756B.

CORTECO 12000756B RUGGERINI 05451

CORTECO 12000756B corresponds to the following RUGGERINI OE reference:

Manufacturer: RUGGERINI

RUGGERINI OE: 05451

CORTECO reference: 12000756B

Dimensions: 40x52x8 mm

Material: ACM

Design: BARS Simmerring

Swirl Type: Left-hand Twist

The RUGGERINI 05451 OE number is an important identification point when searching for the corresponding CORTECO radial shaft oil seal.

The required OE number should be verified against the specific assembly before installation.

RUGGERINI 5451 vs 05451 Oil Seal

The RUGGERINI OE reference catalogued for CORTECO 12000756B is:

RUGGERINI OE: 05451

The same reference may also be searched without the leading zero as:

RUGGERINI: 5451

For complete product identification, 05451 should be retained as the full OE reference.

This allows the product page to remain searchable for both RUGGERINI 05451 oil seal and RUGGERINI 5451 oil seal queries without changing the official reference used in the technical specification.

CORTECO 12000756B Reference Numbers

Manufacturer: CORTECO

Manufacturer reference: 12000756B

Base reference: 12000756

Trade Number: 82000756

Design: BARS Simmerring

RUGGERINI OE: 05451

EAN: 3358960463203

Dimensions: 40x52x8 mm

Material: ACM

Swirl Type: Left-hand Twist

These references and technical characteristics should be considered together when identifying CORTECO 12000756B or selecting a corresponding replacement.

CORTECO 12000756B vs Standard 40x52x8 Oil Seal

A standard radial shaft oil seal measuring 40x52x8 mm should not automatically be considered equivalent to CORTECO 12000756B.

CORTECO 12000756B combines:

Dimensions: 40x52x8 mm

Material: ACM

Design: BARS Simmerring

Swirl Type: Left-hand Twist

RUGGERINI OE: 05451

Matching the 40 mm shaft diameter, 52 mm outside diameter and 8 mm width alone does not confirm that another seal has the same material, construction or directional sealing geometry.

The complete specification should therefore be checked before selecting a replacement.

CORTECO 12000756B ACM vs NBR 40x52x8 Oil Seal

CORTECO 12000756B is manufactured from:

Material: ACM - Polyacrylate Rubber

An NBR 40x52x8 oil seal uses a different elastomer.

Matching the 40x52x8 mm dimensions does not establish material equivalence between ACM and NBR versions.

The required material should be selected according to the medium and actual operating conditions.

The exact BARS design and left-hand twist geometry should also be considered when comparing potential replacements.

Can Any 40x52x8 Oil Seal Replace CORTECO 12000756B?

No. Matching dimensions alone are not sufficient to establish complete technical interchangeability.

For CORTECO 12000756B, the relevant identification includes:

Dimensions: 40x52x8 mm

Material: ACM

Design: BARS Simmerring

Swirl Type: Left-hand Twist

RUGGERINI OE: 05451

Manufacturer reference: 12000756B

A potential replacement should be evaluated against the complete technical specification and the requirements of the specific application.

How to Select a Replacement for CORTECO 12000756B

When selecting a corresponding radial shaft oil seal, verify:

• CORTECO reference 12000756B
• RUGGERINI OE 05451
• dimensions 40x52x8 mm
• shaft diameter 40 mm
• outside diameter 52 mm
• width 8 mm
• material ACM
• design BARS Simmerring
• sealing geometry Left-hand Twist
• actual operating requirements of the application

Matching the 40x52x8 mm dimensions alone does not confirm complete technical interchangeability.
