CORTECO 12010819 18x35x10 NBR BA Rotary Shaft Seal

CORTECO 12010819 18x35x10 NBR BA Rotary Shaft Seal

CORTECO 12010819 is a radial shaft seal / rotary shaft seal / oil seal with nominal dimensions of 18x35x10 mm, manufactured from NBR - Nitrile Butadiene Rubber. CORTECO identifies the seal design as BA. The complete technical identification is CORTECO + 12010819 + 18x35x10 mm + NBR + BA.

CORTECO 12010819 - Technical Characteristics

The verified identification data are:

Manufacturer: CORTECO

Part number: 12010819

Product type: Radial shaft seal / rotary shaft seal / oil seal

Material: NBR

Material name: Nitrile Butadiene Rubber

Design / profile: BA

Dimensions: 18x35x10 mm

Inside diameter d: 18 mm

Outside diameter D: 35 mm

Height H: 10 mm

EAN: 3358960108197

The combination:

CORTECO + 12010819 + NBR + BA + 18x35x10

provides precise identification of this seal.

The CORTECO part number 12010819 is particularly important because dimensions alone do not identify the complete construction or material specification.

CORTECO 12010819 Dimensions

The nominal dimensions are:

d = 18 mm - inside diameter / nominal shaft diameter

D = 35 mm - outside diameter

H = 10 mm - height

Complete dimensions:

18x35x10 mm

CORTECO catalogue data identify this reference as:

12010819 | NBR | BA | 18 | 35 | 10

confirming the part number, material, design and complete dimensional combination.

The first dimension corresponds to the nominal shaft diameter associated with the dynamic sealing interface.

The second dimension defines the nominal outside diameter of the seal and the corresponding housing dimension.

The third dimension specifies the nominal height of the seal.

All three dimensions should be verified when identifying or selecting a replacement.

CORTECO BA Seal Design

The verified CORTECO design designation is:

BA

This designation is an integral part of the exact specification:

CORTECO 12010819 NBR BA

It should not be replaced with AO/TC simply because other 18x35x10 NBR radial shaft seals are available in double-lip configurations.

For precise product identification:

CORTECO 12010819 = NBR BA

while:

GRN® 18x35x10 = NBR AO/TC / TC

represents a different construction designation.

The two products share the same principal dimensions and NBR material, but this alone does not establish identical construction.

Without product-specific CORTECO documentation defining additional lip geometry for this exact BA reference, an auxiliary dust lip should not be assigned to CORTECO 12010819.

How Does a Radial Shaft Seal Work?

A radial shaft seal creates a sealing interface between a rotating shaft and a stationary housing.

For CORTECO 12010819, the nominal shaft dimension is:

d = 18 mm

The nominal outside diameter is:

D = 35 mm

and the nominal axial height is:

H = 10 mm

The sealing element operates at the shaft interface while the outside diameter locates the seal in the housing.

Actual sealing performance also depends on the condition of the shaft surface, installation, alignment, operating medium and operating conditions.

NBR - Nitrile Butadiene Rubber

CORTECO specifies the sealing material as:

NBR - Nitrile Butadiene Rubber

NBR is therefore an integral part of the exact product identification:

12010819 + NBR + BA

A dimensionally identical 18x35x10 mm radial shaft seal manufactured from FPM/FKM, ACM, MVQ or another elastomer should not automatically be considered the same technical variant.

The available product-specific data do not confirm the exact NBR compound, Shore hardness, maximum operating temperature, pressure capability or maximum shaft speed for CORTECO 12010819.

These parameters should therefore not be transferred from other CORTECO seals or dimensionally similar products from other manufacturers.

CORTECO 12010819 vs GRN® 18x35x10 NBR TC

Both products have nominal dimensions of:

18x35x10 mm

and both specify:

NBR

However, their construction designations differ:

CORTECO 12010819 - NBR BA

GRN® 18x35x10 - NBR TC

The GRN® TC variant is identified as a double-lip construction with an auxiliary dust lip, while the verified CORTECO 12010819 data specify BA.

The products should therefore not be treated as identical solely because their dimensions and elastomer family match.

Technical interchangeability requires comparison of the actual sealing construction and operating requirements.

Catalogue Applications and OEM References

CORTECO catalogue data associate 12010819 with FIAT.

Parts catalogue data additionally list the following OEM references:

FIAT: 4230560

FORD: 1491853

FORD: 1549132

Additional Ford references found in parts catalogue data include:

FORD: 715F2A909AA

FORD: 735F9E596AAA

An OEM reference should always be checked against the specific vehicle, assembly or original component before ordering.

Why Is the Full CORTECO 12010819 Identification Important?

The dimensional designation:

18x35x10

defines the principal installation dimensions.

It does not independently identify:

manufacturer

part number

elastomer material

seal design

For this product, the complete identification is:

CORTECO + 12010819 + 18x35x10 + NBR + BA

Retaining all of these parameters helps distinguish CORTECO 12010819 from other 18x35x10 mm radial shaft seals.

Selection and Interchangeability

When selecting CORTECO 12010819 or evaluating a possible replacement, verify at least:

CORTECO part number 12010819

d = 18 mm

D = 35 mm

H = 10 mm

Material = NBR

Design = BA

Operating medium

Actual operating conditions

OEM reference when selection is application-based

Matching 18x35x10 mm dimensions alone does not establish complete technical interchangeability.

This is particularly relevant because 18x35x10 NBR radial shaft seals are also available in other designs, including double-lip TC/AO configurations.

Direct interchangeability with GRN®, SKF, Freudenberg/Simrit or another manufacturer should only be stated after the complete technical specifications have been compared.

Shaft Surface Inspection Before Installation

Before installing the seal, inspect the shaft surface in the sealing contact zone.

Check for:

wear grooves

scratches

corrosion

burrs

mechanical damage

surface contamination

The sealing element should also be protected from sharp edges, threads and grooves during installation.

Damage to the sealing edge or shaft contact surface can interfere with the intended sealing interface.
