Technical data - CORTECO 01031702

What does CORTECO 01031702 NBR BASLDRWX27 mean?

The complete product identification is:

CORTECO 01031702 NBR BASLDRWX27 28x45x10 mm

Each element is relevant when identifying the correct replacement seal.

CORTECO - manufacturer of the seal.

01031702 - specific CORTECO catalogue number.

NBR - Nitrile Butadiene Rubber, the elastomer used in the sealing element.

BASLDRWX27 - construction designation for this specific seal version.

28x45x10 mm - nominal dimensions of the radial shaft seal.

The complete BASLDRWX27 designation is an important part of the technical identification. A replacement should not be selected solely because it has the same 28x45x10 mm dimensions.

Dimensions of CORTECO 01031702

The nominal dimensions are:

28x45x10 mm

where:

• d = 28 mm - inside diameter
• D = 45 mm - outside diameter
• B = 10 mm - width

These dimensions define the basic installation geometry.

They do not, however, fully define the functional construction of the seal.

Two radial shaft seals with identical 28x45x10 mm dimensions may differ in elastomer material, primary lip geometry, additional dust protection and other construction details.

NBR - Nitrile Butadiene Rubber

CORTECO 01031702 is manufactured from:

NBR - Nitrile Butadiene Rubber

NBR is one of the most widely used elastomers for radial shaft oil seals and is commonly used in applications involving compatible mineral oils, lubricants and greases.

When evaluating this seal for a particular application, consider:

• operating medium
• operating temperature
• shaft surface speed
• lubrication conditions
• pressure
• shaft surface condition
• requirements of the equipment manufacturer

A universal temperature range should not be assumed for every NBR seal. Actual operating limits depend on the specific elastomer compound and application conditions.

BASLDRWX27 construction

A key element of the CORTECO 01031702 designation is:

BASLDRWX27

This construction code should be retained when identifying the seal or searching for a technically suitable alternative.

For this product, an additional dust lip is also specified.

Therefore, when comparing CORTECO 01031702 with another radial shaft seal, it is not sufficient to check only:

28x45x10 mm

and:

NBR

The complete sealing construction should also be considered.

Additional dust lip

CORTECO 01031702 incorporates an additional dust sealing lip.

Its purpose is to help protect the primary sealing area against contamination coming from the external environment.

This can be particularly relevant in assemblies exposed to:

• dust
• dirt
• moisture
• operational contamination
• external debris

The dust lip performs a different function from the primary sealing lip.

A simpler 28x45x10 mm radial shaft seal without the corresponding protective lip should therefore not automatically be considered a complete technical replacement.

Why is the BASLDRWX27 construction important?

Radial shaft seals are often searched for only by their dimensions.

For CORTECO 01031702, the more precise identification is:

CORTECO 01031702 NBR BASLDRWX27 28x45x10 mm

rather than simply:

28x45x10 oil seal

The complete designation identifies:

• manufacturer
• exact CORTECO part number
• NBR material
• BASLDRWX27 construction
• 28x45x10 mm dimensions
• additional dust protection

This is especially important when identifying a seal for the corresponding ZF assembly.

CORTECO 01031702 vs ZF 0734309047

The reference associated with CORTECO 01031702 is:

ZF 0734309047

The ZF number is an important identification point when selecting the seal for the corresponding assembly.

For technical cross-reference verification, compare:

ZF 0734309047

with:

CORTECO 01031702

NBR

BASLDRWX27

28x45x10 mm

Using the complete set of identifiers reduces the risk of selecting another 28x45x10 mm seal with a different construction.

Alternative designations and reference numbers

The product may be searched using the following identification variants:

• NBR oil seal 28x45x10
• ZF 0734309047 oil seal
• ZF 0734309047 CORTECO
• CORTECO 01031702 ZF

Reference number:

ZF

• 0734309047

When searching by the ZF reference, the dimensions and complete construction should also be compared before installation.

CORTECO 01031702 vs other 28x45x10 oil seals

Not every radial shaft oil seal with dimensions:

28x45x10 mm

is automatically interchangeable with CORTECO 01031702.

At minimum, compare:

• 28 mm inside diameter
• 45 mm outside diameter
• 10 mm width
• NBR material
• BASLDRWX27 construction
• additional dust lip
• ZF reference
• installation position
• operating medium
• operating conditions

Identical dimensions confirm similar basic installation geometry only.

They do not automatically confirm identical sealing construction or complete functional interchangeability.

How to select CORTECO 01031702 correctly

The safest starting point is the part number on the existing seal or the technical documentation for the assembly.

If the existing product is identified as:

CORTECO 01031702

also verify:

NBR

BASLDRWX27

28x45x10 mm

If the seal is being selected by the equipment manufacturer's reference, verify:

ZF 0734309047

If no readable part number remains on the old seal, accurately measure the shaft diameter, housing bore and seal width, and identify the original sealing construction.

Selection and interchangeability checklist

Before purchasing CORTECO 01031702, verify:

• CORTECO part number 01031702
• BASLDRWX27 construction
• NBR material
• dimensions 28x45x10 mm
• additional dust lip
• ZF reference 0734309047
• exact installation position
• operating medium
• operating temperature
• shaft surface speed
• shaft sealing surface condition

If any important parameter differs from the original seal, interchangeability should be confirmed before installation.

Installation of CORTECO 01031702

Before installation, thoroughly clean the shaft and seal housing.

Inspect the sealing surface for:

• scratches
• corrosion
• burrs
• sharp edges
• mechanical damage
• wear grooves from the previous seal

During installation, protect both the primary sealing lip and the additional dust lip.

If the seal must pass over a thread, spline or sharp shaft edge, appropriate installation protection should be used to prevent lip damage.

The seal should be pressed into the housing evenly and squarely using a suitable installation tool.

Avoid applying direct impact force to the functional sealing elements.

Why can a new radial shaft seal still leak?

Oil leakage does not always mean that the seal itself is defective.

When replacing the seal, also inspect:

• shaft sealing surface
• shaft wear groove
• shaft runout
• alignment
• bearing play
• seal housing
• installation position
• operating conditions

A damaged shaft surface or excessive shaft movement can cause leakage even when the correct CORTECO 01031702 seal has been installed.
