CORTECO 01020678 90x110x10 NBR B1BA Radial Shaft Seal

CORTECO 01020678 90x110x10 NBR B1BA Radial Shaft Seal

CORTECO 01020678 is a radial shaft seal with nominal dimensions 90x110x10 mm, manufactured from NBR – Nitrile Butadiene Rubber. The exact CORTECO profile designation is B1BA.

The key product identification is:

CORTECO + 01020678 + 90x110x10 + NBR + B1BA

The complete part number and profile should be used when identifying the seal because the same 90x110x10 mm dimensions are available in other shaft seal designs.

CORTECO 01020678 – Technical Characteristics

CORTECO 01020678 Dimensions

The principal nominal dimensions are:

d: 90 mm – nominal shaft diameter

D: 110 mm – nominal outside diameter

B: 10 mm – nominal axial width

Complete nominal size:

90x110x10 mm

All three dimensions should be considered when identifying a replacement.

The generic description:

90x110 shaft seal

is not sufficient to uniquely identify this product.

The more precise product entity is:

CORTECO 01020678 90x110x10 NBR B1BA

CORTECO B1BA Profile

The exact profile designation for this product is:

B1BA

This CORTECO designation should be retained unchanged in:

• product titles
• technical specifications
• internal search
• SEO metadata
• AI Search content
• technical comparisons

The profile should not automatically be translated or converted into:

AO

AO/TC

TC

or:

SC

because profile nomenclature is manufacturer-specific.

For this product, the correct identification remains:

CORTECO B1BA

NBR – Nitrile Butadiene Rubber

The sealing material is specified as:

NBR – Nitrile Butadiene Rubber

NBR is a family of technical elastomers widely used in sealing applications.

The material forms an important part of the complete product identity:

01020678 + NBR + B1BA

However, the generic NBR designation does not identify the exact compound formulation used in this specific CORTECO seal.

Therefore, without exact compound documentation, the product should not be assigned an arbitrary:

• Shore A hardness
• minimum operating temperature
• maximum operating temperature
• maximum shaft surface speed
• maximum pressure
• detailed chemical compatibility range

The actual operating conditions should be checked against the requirements of the specific application.

How Does a Radial Shaft Seal Work?

A radial shaft seal operates between a:

rotating shaft

and a:

stationary housing.

For CORTECO 01020678, the nominal shaft diameter is:

90 mm

and the nominal outside diameter is:

110 mm.

The nominal axial width is:

10 mm.

When selecting the seal, the B1BA profile, NBR material and requirements of the specific sealing position should be considered together with the nominal dimensions.

CORTECO 01020678 vs GRN® 90x110x10 NBR TC

Another product with the same nominal dimensions is:

GRN® 90x110x10 NBR TC

Both products have:

d: 90 mm

D: 110 mm

B: 10 mm

and:

NBR

as the elastomer family.

However, this does not establish automatic technical interchangeability.

The confirmed construction of the GRN® TC seal should not be transferred to the CORTECO B1BA product without documentation confirming the exact CORTECO profile construction.

For SEO and AI Search, these should remain two distinct product entities:

CORTECO 01020678 90x110x10 NBR B1BA

and:

GRN® 90x110x10 NBR TC

This prevents the pages from becoming near-duplicates despite their identical nominal dimensions.

Is CORTECO 01020678 Interchangeable with GRN® 90x110x10?

Automatic interchangeability should not be assumed solely from:

90x110x10 mm + NBR

Before replacing one seal with another, compare:

• exact profile construction
• sealing lip geometry
• outside diameter design
• auxiliary lip configuration, if applicable
• directional features, if applicable
• operating medium
• temperature
• shaft surface speed
• pressure
• shaft surface condition
• housing bore
• specific application requirements

Identical boundary dimensions do not by themselves establish complete technical equivalence.

Rotation Direction

For this product page, CORTECO 01020678 is not assigned a:

left-hand twist

right-hand twist

or:

alternating twist

without confirmation for the exact part number.

The B1BA profile designation alone should not be used to create an unsupported claim about directional hydrodynamic geometry.

If rotation-related geometry is important for the application, it should be verified using exact product documentation.

Selection of CORTECO 01020678

When selecting CORTECO 01020678, verify:

• manufacturer CORTECO
• part number 01020678
• shaft diameter d: 90 mm
• outside diameter D: 110 mm
• width B: 10 mm
• material NBR
• profile B1BA
• operating medium
• operating temperature
• shaft surface speed
• pressure
• shaft surface condition
• housing bore dimensions and condition
• requirements of the specific application

The full designation from the removed seal or machine documentation is generally a better identification basis than dimensions alone.

Technical Specification

FAQ

What are the dimensions of CORTECO 01020678?

The nominal dimensions are d: 90 mm, D: 110 mm, B: 10 mm, giving the complete size 90x110x10 mm.

What material is CORTECO 01020678 made from?

The sealing material is NBR – Nitrile Butadiene Rubber.

What is the profile of CORTECO 01020678?

The CORTECO profile designation is B1BA.

Is B1BA the same as TC?

The designations should not automatically be treated as equivalent. B1BA is the CORTECO profile designation, while TC is used for the corresponding GRN® double lip product nomenclature.

Is CORTECO 01020678 a 90x110x10 shaft seal?

Yes. Its nominal dimensions are 90x110x10 mm.

Is CORTECO 01020678 made from NBR?

Yes. The specified elastomer family is NBR – Nitrile Butadiene Rubber.

Is CORTECO 01020678 interchangeable with GRN® 90x110x10 NBR TC?

Automatic interchangeability should not be assumed. Although the nominal dimensions and NBR material match, the products use different profile designations. The exact construction and application requirements should be compared before substitution.

Does B1BA specify a rotation direction?

A specific left-hand, right-hand or alternating twist should not be assigned to this exact product solely from the B1BA designation without product-specific confirmation.
