Technical specifications

OE cross-reference numbers

The following references are associated with CORTECO 12011009 in replacement-parts catalogues.

These references support product identification but do not guarantee compatibility with every machine manufactured by the listed brands.

The exact application should be verified using the original equipment documentation, machine model and relevant assembly information.

CORTECO 12011009 – catalogue identification

The CORTECO dimensional catalogue identifies 12011009B as a radial shaft seal with dimensions of 65x90x10 mm, NBR material and a BA sealing profile.

The references 12011009 and 82011009 also appear in replacement-parts listings.

The four OE numbers provided above are associated with this product family in aftermarket cross-reference catalogues.

When ordering, the current manufacturer reference and the complete technical designation should be verified.

What does CORTECO 12011009 NBR BA 65x90x10 mean?

The product designation identifies the brand, article reference, dimensions, elastomer material and sealing profile.

• CORTECO – manufacturer brand.

• 12011009 – product catalogue reference.

• 65 mm – nominal shaft diameter.

• 90 mm – nominal housing bore diameter.

• 10 mm – nominal axial width.

• NBR – nitrile butadiene rubber.

• BA – radial shaft seal profile with a rubber-covered outer diameter and spring-loaded primary sealing lip.

The complete designation is important when checking compatibility with an existing sealing arrangement.

BA sealing profile – construction and operating principle

The BA profile is a conventional radial shaft sealing design used in rotating shaft applications.

Its typical construction includes three principal components.

1. Rubber-covered outer diameter

The elastomeric outer surface helps provide a secure seal between the component and the housing bore.

It can accommodate minor housing surface irregularities within the manufacturer's permissible tolerances.

2. Internal metal reinforcement

The metal reinforcing insert provides dimensional stability and helps maintain the shape of the seal during installation and operation.

3. Spring-loaded primary sealing lip

The primary sealing lip maintains contact with the rotating shaft surface.

A garter spring helps maintain the required radial contact force, supporting lubricant retention during operation.

The standard BA profile does not incorporate an additional dust lip.

Where additional protection against external contamination is required, a different sealing profile may be necessary.

NBR material properties

NBR is a synthetic elastomer produced from acrylonitrile and butadiene.

It is widely used in radial shaft seals because of its compatibility with many mineral oil-based lubricants.

Typical characteristics of appropriately selected NBR compounds include:

• Good resistance to many mineral oils.

• Compatibility with numerous industrial lubricating greases.

• Suitable mechanical properties under appropriate operating conditions.

• Application in mechanical transmissions and drive assemblies.

• Effective sealing performance with compatible lubricants.

NBR is not universally resistant to all fuels, solvents or industrial chemicals.

Its resistance to ozone and certain atmospheric influences is limited.

The exact operating temperature range depends on the specific elastomer compound.

For CORTECO 12011009, maximum temperature, permissible pressure and shaft speed should not be specified without manufacturer documentation.

BA, BASL and B1 sealing profiles compared

Seals with identical nominal dimensions but different profiles should not automatically be considered interchangeable.

Selection depends on housing design, contamination exposure, operating medium and installation requirements.

Selection and interchangeability

Before selecting CORTECO 12011009, verify:

1. Nominal shaft diameter – 65 mm.

2. Nominal housing bore diameter – 90 mm.

3. Installation width – 10 mm.

4. Required BA sealing profile.

5. Compatibility of NBR with the operating medium.

6. Operating temperature and shaft peripheral speed.

7. Pressure within the sealed chamber.

8. Shaft surface roughness, hardness and condition.

9. Lubrication requirements.

10. Original equipment reference for the specific assembly.

Matching dimensions alone do not guarantee interchangeability.

A replacement seal must also provide the required sealing profile, material compatibility and operating characteristics.

Applications – DANA, MERLO, NEW HOLLAND and SAME

Replacement-parts catalogues associate CORTECO 12011009 with components used by DANA, MERLO, NEW HOLLAND and SAME.

These references may relate to agricultural machinery, material-handling equipment and mechanical drive assemblies.

Radial shaft seals of this construction may also be used in appropriately designed:

• Mechanical gearboxes.

• Transmission assemblies.

• Agricultural machinery.

• Industrial drive systems.

• Bearing housings.

• Rotating shaft mechanisms.

These are potential application areas rather than verified fitment information for individual machines.

The original equipment reference must be checked against the specific mechanical assembly.

Alternative designations and search references

Common English technical designations include:

• CORTECO 12011009

• CORTECO 12011009B

• CORTECO 82011009

• CORTECO 12011009 NBR BA

• CORTECO 65x90x10 NBR BA Oil Seal

• CORTECO 12011009 Radial Shaft Seal

• CORTECO 65x90x10 BA Rotary Shaft Seal

• Radial Shaft Seal 65x90x10 NBR BA

• Rotary Oil Seal 65x90x10 NBR

These are catalogue and descriptive references. They do not independently establish compatibility with other manufacturer part numbers.

Installation and operating recommendations

Before installation, inspect the housing bore and shaft surface.

Both surfaces should be clean and free from scratches, burrs, corrosion and excessive wear.

Install the seal evenly using suitable mounting tools.

Avoid applying installation force directly to the sealing lip.

In conventional applications, the spring-loaded primary sealing lip faces the medium being retained unless the equipment documentation specifies otherwise.

Before operation, provide appropriate lubrication at the contact area between the sealing lip and shaft.

Dry running, excessive shaft runout, incorrect surface roughness or improper installation may cause premature wear and lubricant leakage.

FAQ – Frequently asked questions

1. What are the dimensions of CORTECO 12011009?

The nominal shaft diameter is 65 mm, the housing bore diameter is 90 mm, and the axial width is 10 mm.

2. What does the BA sealing profile mean?

BA identifies a radial shaft seal with a rubber-covered outer diameter and a spring-loaded primary sealing lip.

3. Does CORTECO 12011009 have an additional dust lip?

The standard BA profile does not incorporate an additional dust lip.

4. Are CORTECO 12011009 and 12011009B the same product?

Available catalogues associate these references with dimensions of 65x90x10 mm, NBR material and a BA profile. The current manufacturer reference should be confirmed before ordering.

5. Is CORTECO 12011009 equivalent to DANA 001010573?

DANA 001010573 appears in replacement-parts cross-reference listings for CORTECO 12011009B. Compatibility must be verified for the specific assembly.

6. Is CORTECO 12011009 suitable for MERLO machinery?

Replacement-parts catalogues list MERLO 003397AA as a corresponding reference. This does not establish compatibility with every MERLO model.

7. What are the NEW HOLLAND and SAME OE references?

The listed references are NEW HOLLAND 80536079 and SAME 215101340.

8. Is NBR suitable for gearbox oil?

Appropriately selected NBR compounds are compatible with many mineral oil-based lubricants. Compatibility with a specific gearbox oil must be verified.
