CORTECO 12010770 NBR BA 12x19x5 mm Oil Seal

CORTECO 12010770 NBR BA 12x19x5 mm Oil Seal

CORTECO 12010770 NBR BA 12x19x5 mm is a radial shaft seal manufactured from NBR nitrile rubber. Its catalogue design is specified as BA. The seal is designed for a nominal 12 mm shaft, has a 19 mm outside diameter and a width of 5 mm. CORTECO reference 12010770 provides precise product identification when selecting or replacing this rotary shaft seal.

Technical data - CORTECO 12010770

CORTECO 12010770 dimensions

The principal dimensions are:

d = 12 mm - nominal shaft diameter

D = 19 mm - nominal outside diameter

b = 5 mm - nominal seal width

Complete dimensions:

12x19x5 mm

When selecting an equivalent seal, all three dimensions should be checked together with the elastomer material and seal design.

What does BA mean?

CORTECO specifies the design of reference 12010770 as:

BA

This is an important part of the complete technical identification:

CORTECO 12010770 NBR BA 12x19x5 mm

The BA design should be distinguished from seal configurations incorporating an additional auxiliary dust lip.

For this reason, CORTECO 12010770 should not automatically be described as equivalent to an AO/TC double-lip seal solely because the dimensions are also 12x19x5 mm.

NBR nitrile rubber

CORTECO 12010770 is manufactured from:

NBR - Nitrile Butadiene Rubber

NBR is one of the most widely used elastomers in radial shaft sealing technology.

Typical characteristics of NBR include:

• good resistance to many mineral oils

• good resistance to many greases

• good mechanical properties

• good abrasion resistance

• widespread use in industrial sealing applications

Material compatibility must always be considered in relation to the actual operating medium, temperature and application conditions.

NBR is not universally resistant to every chemical or temperature environment.

How does CORTECO 12010770 work?

The seal is installed in a housing with a nominal bore diameter of 19 mm.

Its sealing lip operates against a rotating shaft with a nominal diameter of 12 mm.

The function of a radial shaft seal is to restrict the movement of lubricant or another compatible medium along the rotating shaft between moving and stationary components.

Correct sealing performance depends not only on the seal itself but also on shaft surface quality, installation, lubrication, temperature, rotational speed and operating medium.

CORTECO 12010770 BA vs AO/TC 12x19x5

Two seals can have exactly the same principal dimensions:

12x19x5 mm

while having different designs.

CORTECO 12010770 - BA design

should not automatically be treated as identical to:

12x19x5 AO/TC

simply because their dimensions match.

AO/TC is used for configurations incorporating an additional dust lip, while the correct catalogue design designation for CORTECO 12010770 is BA.

Both dimensions and seal construction should therefore be verified when selecting a replacement.

NBR vs FPM/FKM

12x19x5 mm rotary shaft seals can be manufactured from different elastomer materials.

NBR is widely used in standard applications involving many mineral oils and greases.

FPM/FKM belongs to the fluoroelastomer family and provides a different chemical and temperature resistance profile.

Identical dimensions do not automatically mean identical operating characteristics.

The elastomer should be selected according to:

• operating medium

• temperature

• shaft speed

• environmental conditions

• complete sealing arrangement

CORTECO 12010770 vs 12011714

CORTECO catalogues also list:

12011714 FPM BAVIX7 12x19x5

Both products have the same principal dimensions:

12x19x5 mm

but differ in material and design designation.

12010770 - NBR BA

12011714 - FPM BAVIX7

They should therefore not be considered automatically identical or interchangeable products.

Typical applications

Radial shaft seals of this type are used in many mechanical systems incorporating rotating shafts.

Typical application areas for radial shaft seals include:

• gearboxes

• drive systems

• pumps

• motors

• rotating mechanisms

• industrial machinery

• mechanical equipment

• oil- and grease-lubricated assemblies

These are typical applications of radial shaft seals and do not confirm the suitability of CORTECO 12010770 for a specific machine.

Selection should be based on the product reference, dimensions and operating conditions.

Selection and interchangeability

When selecting an equivalent for CORTECO 12010770, verify:

• product reference

• shaft diameter 12 mm

• outside diameter 19 mm

• width 5 mm

• BA design

• NBR material

• operating medium

• operating temperature

• shaft rotational speed

• shaft surface quality

• pressure conditions

Matching the 12x19x5 mm dimensions alone does not guarantee complete interchangeability.

Seals of identical dimensions may differ in elastomer, lip geometry, external construction and intended operating conditions.

Installation

Before installation, inspect the shaft and seal housing.

The shaft surface operating against the sealing lip should be clean and free from corrosion, scratches, sharp edges or other damage that could affect sealing performance.

During installation:

• maintain clean working conditions

• protect the sealing lip from sharp edges

• avoid installing the seal at an angle

• press the seal evenly into the housing

• avoid damaging the elastomer surface

• provide appropriate initial lubrication where required

Correct installation has a direct influence on the service life and performance of a radial shaft seal.
