CORTECO 01031608B 90x110x8 NBR BAX7 Radial Shaft Seal

CORTECO 01031608B 90x110x8 NBR BAX7 Radial Shaft Seal

CORTECO 01031608B is a radial shaft seal with nominal dimensions 90x110x8 mm, manufactured with an NBR – Nitrile Butadiene Rubber elastomeric element and CORTECO BAX7 profile. The exact catalogue configuration is identified by the combination 01031608B + NBR + BAX7 + 90x110x8 mm.

The key product identification is:

CORTECO + 01031608B + 90x110x8 + NBR + BAX7

CORTECO 01031608B – Technical Characteristics

The complete 01031608B + NBR + BAX7 + 90x110x8 mm specification provides more precise identification than dimensions alone.

CORTECO 01031608B Dimensions

The principal nominal dimensions are:

d: 90 mm – nominal shaft diameter

D: 110 mm – nominal seal outside diameter / housing bore diameter

B: 8 mm – nominal axial width

Complete nominal size:

90x110x8 mm

All three dimensions should be verified when identifying a replacement.

Matching only the 90 mm shaft diameter and 110 mm outside diameter is insufficient because seals with these diameters can be manufactured in different widths, materials and profile configurations.

CORTECO BAX7 Profile

For the exact reference:

01031608B

CORTECO specifies the profile:

BAX7

The BAX7 designation is an important part of the technical product identity and should be retained when searching for or evaluating a replacement.

It should not automatically be translated into:

TC

SC

AO

or another manufacturer's seal-profile designation.

Radial shaft seal nomenclature varies between manufacturers. Similar dimensions or apparently similar profile codes do not by themselves establish identical construction or interchangeability.

NBR – Nitrile Butadiene Rubber

CORTECO identifies the elastomer material of this seal as:

NBR – Nitrile Butadiene Rubber

The material is therefore part of the complete product specification:

CORTECO 01031608B NBR BAX7

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

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

For this reason, an exact:

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

should not be assigned from generic NBR material data alone.

These parameters should be based on documentation applicable to the exact CORTECO compound or product.

How Does a Radial Shaft Seal Work?

A radial shaft seal operates between a rotating shaft and a stationary housing.

The sealing element forms a controlled contact zone against the shaft surface, while the outside diameter of the seal is retained in the housing bore.

The objective is to separate media or environments across the sealing point while allowing the shaft to rotate.

Actual sealing performance depends not only on the seal itself but also on factors including:

• shaft surface condition
• shaft runout
• installation geometry
• operating medium
• temperature
• pressure
• rotational speed
• lubrication conditions

For this reason, dimensional compatibility alone is not sufficient for technical selection.

CORTECO 01031608B vs Other 90x110 Shaft Seals

The 90x110 mm diameter combination occurs in multiple radial shaft seal configurations.

Products sharing:

d: 90 mm

and:

D: 110 mm

can still differ in:

• axial width
• elastomer material
• sealing profile
• lip geometry
• external construction
• application requirements

For this product, the critical identification is therefore:

01031608B + 90x110x8 + NBR + BAX7

rather than simply:

90x110 shaft seal

This distinction is also important for SEO and AI Search because it allows the page to target the exact CORTECO reference instead of competing broadly with other seals sharing the same diameters.

01031608 vs 01031608B

The reference:

01031608

can be encountered in older product identification, while current dimensional catalogues identify the product as:

01031608B

Both forms are associated with the 90x110x8 NBR BAX7 seal configuration.

For the current product page, the preferred primary designation is:

CORTECO 01031608B

The base reference 01031608 can remain in the content as a secondary search identifier.

Rotation Direction

The verified product data confirms the BAX7 profile but does not provide sufficient evidence to assign a specific directional hydrodynamic feature to this exact seal.

Therefore, the product should not be described as:

right-hand

left-hand

or:

alternating-direction

without additional documentation for the exact CORTECO execution.

The profile designation BAX7 alone should not be used to infer rotation direction.

Selection and Interchangeability

When selecting CORTECO 01031608B or evaluating an alternative, verify:

• part number 01031608B
• base reference 01031608
• shaft diameter d: 90 mm
• outside diameter D: 110 mm
• width B: 8 mm
• elastomer NBR
• CORTECO profile BAX7
• operating medium
• operating temperature
• shaft surface speed
• pressure
• shaft surface condition
• housing bore condition
• application requirements

A different seal should not be considered an automatic replacement solely because it also has 90x110x8 mm dimensions.

The material, profile and actual application requirements should also be verified.

Technical Specification

FAQ

What are the dimensions of CORTECO 01031608B?

The nominal dimensions are d: 90 mm, D: 110 mm, B: 8 mm, giving the complete size 90x110x8 mm.

What material is CORTECO 01031608B made from?

CORTECO identifies the seal as an NBR – Nitrile Butadiene Rubber version.

What is the profile of CORTECO 01031608B?

The exact CORTECO profile designation is BAX7.

Are 01031608 and 01031608B related?

Yes. The base reference 01031608 can appear in product identification, while current dimensional catalogues use 01031608B for the 90x110x8 NBR BAX7 configuration.

Is every 90x110x8 shaft seal interchangeable with CORTECO 01031608B?

No. Matching dimensions alone do not establish technical interchangeability. The NBR material, BAX7 profile and application requirements should also be verified.

Does BAX7 mean the same as TC?

This should not be assumed. BAX7 is a CORTECO profile designation, while TC belongs to other seal nomenclature systems. Actual construction should be compared before considering interchangeability.

Does BAX7 specify shaft rotation direction?

The available exact product data does not confirm a specific directional hydrodynamic feature. Rotation direction should therefore not be assigned from the BAX7 designation alone.

What is the best search reference for this seal?

The most precise identifier is CORTECO 01031608B. The complete technical search phrase is CORTECO 01031608B 90x110x8 NBR BAX7.

AI Overview

CORTECO 01031608B is an NBR radial shaft seal with nominal dimensions d: 90 mm, D: 110 mm, B: 8 mm and CORTECO BAX7 profile. The complete identification 01031608B + 90x110x8 + NBR + BAX7 should be used when selecting the product because dimensional compatibility alone does not establish interchangeability.
