CORTECO 12010917 NBR BAX7 36x47x7 Radial Shaft Seal

Technical specifications

OE cross-reference numbers

Replacement-parts catalogues associate the following original equipment references with CORTECO 12010917B.

These references support component identification but do not guarantee compatibility with every machine or mechanical assembly manufactured by the listed companies.

The exact application should be verified using the original equipment documentation and the relevant assembly identification.

CORTECO 12010917 – important catalogue distinction

The CORTECO dimensional catalogue identifies 12010917 – NBR BA – 36x47x7 mm.

However, replacement-parts catalogues identify 12010917B – NBR BAX7 – 36x47x7 mm.

The dimensions and elastomer material are consistent, but the published sealing profile designations differ.

Without additional manufacturer documentation, BA and BAX7 should not be assumed to describe identical sealing lip geometry.

This distinction is particularly important when replacing a seal in an assembly where the original sealing profile is specified.

What does CORTECO 12010917 NBR BAX7 36x47x7 mean?

The product designation identifies the manufacturer, catalogue reference, dimensions, elastomer material and sealing profile.

• CORTECO – manufacturer brand.

• 12010917 – product catalogue reference.

• 36 mm – nominal shaft diameter.

• 47 mm – nominal housing bore diameter.

• 7 mm – nominal axial width.

• NBR – nitrile butadiene rubber.

• BAX7 – sealing profile designation associated with the 12010917B variant in replacement-parts catalogues.

The complete product designation should be preserved when checking replacement compatibility.

BAX7 sealing profile – construction and operating principle

BAX7 is a sealing profile designation used in CORTECO replacement-parts catalogues.

Available catalogue information confirms its association with reference 12010917B but does not establish every detail of its cross-sectional construction.

For correct selection, the following characteristics should be verified:

• Outer surface construction and housing sealing method.

• Primary sealing lip geometry.

• Presence or absence of an additional dust lip.

• Presence of a garter spring.

• Any directional sealing features.

The BAX7 profile should not automatically be assigned all the characteristics of a standard BA seal without confirmation from the manufacturer's technical drawing.

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.

• Mechanical properties suitable for contact-type shaft sealing.

• Application in mechanical transmissions and rotating shaft assemblies.

• Availability of different compounds for specific operating conditions.

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 and chemical compatibility depend on the specific elastomer compound.

For CORTECO 12010917, maximum temperature, permissible pressure and shaft speed should not be specified without manufacturer documentation.

BAX7, BA and BASL sealing profiles compared

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

The correct selection depends on the original equipment requirements, sealing geometry, material compatibility and operating conditions.

Selection and interchangeability

Before selecting CORTECO 12010917, verify:

1. Nominal shaft diameter – 36 mm.

2. Nominal housing bore diameter – 47 mm.

3. Installation width – 7 mm.

4. Exact sealing profile required by the equipment.

5. Compatibility of NBR with the operating medium.

6. Operating temperature and shaft rotational speed.

7. Pressure within the sealed chamber.

8. Shaft surface condition and housing bore tolerances.

9. Original equipment reference.

10. Whether the required designation is 12010917 or 12010917B.

Matching dimensions alone does not guarantee interchangeability.

The replacement must also provide the required sealing profile, elastomer compatibility and operating characteristics.

Applications – CARRARO, FIAT OM and GRAZIANO

Replacement-parts catalogues associate CORTECO 12010917B with the following OE references:

These references indicate applications in relevant mechanical and drive assemblies.

Depending on the original equipment configuration, radial shaft seals of this type may be used in:

• Mechanical transmission assemblies.

• Industrial drive systems.

• Material-handling equipment.

• Rotating shaft mechanisms.

• Gearbox and bearing housing applications.

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

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

Alternative designations and search references

Common English technical designations include:

• CORTECO 12010917

• CORTECO 12010917B

• CORTECO 82010917

• CORTECO 12010917 NBR BAX7

• CORTECO BAX7 36x47x7

• CORTECO 36x47x7 NBR Oil Seal

• CORTECO 12010917 Radial Shaft Seal

• Radial Shaft Seal 36x47x7 NBR

• Rotary Oil Seal 36x47x7

The reference 82010917 also appears in replacement-parts catalogues as an additional commercial designation.

These catalogue and descriptive references do not independently establish interchangeability.

Installation and operating recommendations

Before installation, clean the housing bore and inspect the shaft surface for corrosion, scratches, burrs and excessive wear.

The seal should be installed evenly using suitable mounting tools.

Avoid applying installation force directly to the sealing lip.

Installation orientation must correspond to the original equipment documentation and the confirmed BAX7 sealing profile.

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

Dry running, excessive shaft runout, unsuitable surface roughness and incorrect installation may result in premature wear and lubricant leakage.

FAQ – Frequently asked questions

1. What are the dimensions of CORTECO 12010917?

The nominal dimensions are 36x47x7 mm, corresponding to a 36 mm shaft diameter, 47 mm housing bore diameter and 7 mm width.

2. What does the BAX7 sealing profile mean?

BAX7 is a sealing profile designation used in CORTECO replacement-parts catalogues. Its detailed construction requires confirmation from manufacturer technical documentation.

3. Are CORTECO 12010917 and 12010917B identical?

Both references are associated with dimensions of 36x47x7 mm and NBR material. However, the dimensional catalogue lists BA, while replacement-parts catalogues identify BAX7 for 12010917B. The exact construction should be confirmed.

4. Is CORTECO 12010917 manufactured from NBR?

Yes. NBR is identified in catalogue information for the product references.

5. Is CARRARO 025399 a cross-reference for CORTECO 12010917B?

Yes. CARRARO 025399 appears in replacement-parts cross-reference catalogues. Compatibility with the specific assembly must still be verified.

6. What is the FIAT OM CARELLI ELEV OE reference?

The listed OE reference is 9461939.

7. What GRAZIANO TRASMISSIONI reference is associated with this seal?

The listed reference is 71448.

8. Can a standard BA seal replace the BAX7 profile?

Not automatically. The sealing geometry, operating conditions and original equipment requirements must be verified before substitution.
