CORTECO 12010867 NBR BA 26x47x7 Oil Seal Fiat 5948044 SAME 215103110

What Is the CORTECO 12010867 Oil Seal?

CORTECO 12010867 is an NBR radial shaft oil seal in BA design, with dimensions of 26x47x7 mm. It is cross-referenced with Fiat 5948044 and SAME 215103110. The seal is designed for rotating shaft applications where it helps retain oil or grease inside the mechanical assembly. Its NBR elastomer provides good resistance to mineral oils and lubricating greases commonly encountered in transmissions, agricultural machinery and mechanical drive systems.

What Does 26x47x7 Mean?

The designation 26x47x7 mm defines the three principal installation dimensions of the oil seal:

26 mm - nominal shaft diameter

47 mm - nominal outside diameter of the seal

7 mm - seal width

These dimensions should be verified together with the material, seal design and OE reference when selecting a replacement.

CORTECO 12010867 BA Design

The BA design identifies the construction of this radial shaft seal. Its primary sealing lip operates directly against the rotating shaft surface and is designed to retain lubricant within the mechanical assembly.

Correct seal selection requires more than matching the dimensions. The BA construction, NBR material and application reference should also correspond to the original sealing arrangement.

A different oil seal with the same 26x47x7 mm dimensions should therefore not automatically be considered an equivalent replacement.

NBR Nitrile Rubber Oil Seal

NBR, or Nitrile Butadiene Rubber, is one of the most widely used elastomers for conventional radial shaft seals.

Its relevant properties include:

• Very good resistance to many mineral oils
• Good resistance to lubricating greases
• Good abrasion resistance
• Good mechanical properties
• Suitable elasticity for sealing applications
• Wide applicability in machinery and drive systems

NBR oil seals are commonly used where operating conditions remain within the temperature and chemical resistance capabilities of nitrile rubber.

CORTECO 12010867 Fiat 5948044 Cross Reference

The reference Fiat 5948044 is an important identifier when searching for this replacement oil seal.

For correct identification, compare:

CORTECO: 12010867

Fiat: 5948044

Dimensions: 26x47x7 mm

Material: NBR

Design: BA

Using the OE number together with the CORTECO reference and dimensions provides more precise identification than selecting an oil seal by size alone.

CORTECO 12010867 SAME 215103110 Cross Reference

The SAME 215103110 reference is also associated with this 26x47x7 mm radial shaft seal.

This reference is particularly relevant when identifying sealing components used in compatible agricultural machinery and mechanical assemblies.

The complete identification is therefore:

CORTECO 12010867

SAME 215103110

Fiat 5948044

NBR BA

26x47x7 mm

The actual application should always be verified against the machine documentation, original part number or removed seal.

Applications of the CORTECO 12010867 Oil Seal

The CORTECO 12010867 NBR BA oil seal is intended for compatible rotating shaft sealing arrangements.

Typical application areas for radial shaft seals of this type include:

• Agricultural machinery
• Tractors
• Gearboxes
• Transmission systems
• Gear reducers
• Mechanical drive systems
• Rotating shafts
• Oil-lubricated assemblies
• Industrial machinery
• Machinery repair and maintenance

Exact compatibility should be determined using the CORTECO and OE reference numbers.

Oil and Grease Sealing

The primary purpose of the CORTECO 12010867 radial shaft seal is to retain lubricant inside a mechanical assembly while the shaft rotates.

NBR is particularly useful in applications involving compatible mineral oils and greases. However, actual seal performance depends on several operating factors, including:

• Lubricant type
• Operating temperature
• Shaft speed
• Shaft surface quality
• Shaft runout
• Housing condition
• Installation accuracy

Chemical compatibility should be checked when the seal is exposed to unusual lubricants, fuels or aggressive fluids.

Rotating Shaft Sealing

A radial shaft oil seal operates at the interface between a stationary housing and a rotating shaft.

The sealing lip maintains controlled contact with the shaft surface. This contact helps prevent lubricant from escaping from the assembly.

For reliable operation, the shaft sealing surface should be smooth, correctly dimensioned and free from corrosion or excessive wear.

Selecting a Replacement Oil Seal

When replacing the CORTECO 12010867, verify all important identification parameters:

• CORTECO part number 12010867
• Fiat reference 5948044
• SAME reference 215103110
• Shaft diameter 26 mm
• Outside diameter 47 mm
• Width 7 mm
• NBR material
• BA design
• Operating medium
• Application requirements

Selecting a seal based solely on 26x47x7 mm dimensions may result in an incorrect replacement if the construction or elastomer differs.

Installation Recommendations

Before installing the new 26x47x7 oil seal, clean the housing and inspect the shaft contact surface.

During installation:

• Verify the 26 mm shaft diameter
• Verify the 47 mm housing bore
• Protect the sealing lip from sharp edges
• Avoid damaging or folding the sealing lip
• Press the seal evenly into the housing
• Check the correct installation direction
• Inspect the shaft for wear grooves
• Avoid contaminating the sealing surface
• Protect the sealing lip against dry running during initial operation

Installation force should be applied evenly to avoid deformation of the seal.

Shaft Condition and Oil Seal Life

The condition of the shaft is critical to radial shaft seal performance.

Before fitting a new seal, inspect the shaft for:

• Wear grooves
• Corrosion
• Scratches
• Burrs
• Excessive radial runout
• Surface contamination

A new CORTECO oil seal may still leak if the shaft contact surface is severely worn or damaged.

Machinery Service and Maintenance

Oil leakage around a rotating shaft can indicate deterioration of the radial shaft seal, but the seal itself is not always the only cause.

During servicing, technicians should also inspect:

• Bearings
• Shaft alignment
• Shaft play
• Housing condition
• Lubricant level
• Lubricant contamination
• Operating temperature

Excessive bearing clearance or shaft movement can reduce the operating life of a new oil seal.

Why Identify the Seal by Part Number and OE Reference?

Radial shaft seals with identical nominal dimensions may differ in material, lip geometry or construction.

For this reason, the combination of:

CORTECO 12010867

Fiat 5948044

SAME 215103110

26x47x7 mm

NBR

BA

provides a much more precise product identification than dimensions alone.

This is especially important when sourcing replacement seals for agricultural machinery, transmissions and older mechanical equipment.
