EC 12625 S02H206 25x59x18 mm - Single Row Tapered Roller Bearing

Technical Specifications - EC 12625 S02H206 (NEUTRAL)

The dimensional and application details above relate to the corresponding NTN-SNR reference.

For the NEUTRAL version, the exact geometry, component configuration and manufacturing tolerances should be confirmed before installation.

The NEUTRAL designation does not establish that the bearing was manufactured by NTN-SNR or that all performance specifications are identical.

Dynamic load rating C, static load rating C0, fatigue load limit Pu, limiting speed, bearing mass, cage material and dimensional tolerances are not specified here because they have not been confirmed for the exact NEUTRAL product.

What Does EC 12625 S02H206 Mean?

EC 12625 - Basic Reference Designation

EC 12625 forms the main part of the bearing reference used for a specific tapered roller bearing configuration.

The corresponding reference identifies a bearing with nominal dimensions of 25x59x18 mm.

Its tapered roller construction is intended to accommodate combined radial and axial loading.

The complete designation must be considered when identifying the correct replacement bearing.

S02H206 - Specific Bearing Version

S02H206 is an integral part of the reference designation.

It must not be omitted when identifying or ordering the bearing.

The exact individual meanings of S02 and H206 have not been conclusively established from the available technical information.

Therefore, these elements should not be interpreted as confirmed specifications for internal clearance, cage design, precision class or heat treatment.

NEUTRAL - Commercial Designation

NEUTRAL indicates a product supplied without a clearly identified manufacturer brand.

It does not automatically mean that the bearing is manufactured by NTN-SNR.

Although EC 12625 S02H206 corresponds to an NTN-SNR reference, the manufacturer, cage construction, tolerances and load ratings of the NEUTRAL product require separate verification.

Construction of EC 12625 S02H206

Inner Ring

The inner ring has a nominal bore diameter of 25 mm and is designed to fit onto a correctly dimensioned shaft journal.

Its tapered raceway works together with the rolling elements to transmit loads between the bearing rings.

Correct shaft fit is important for maintaining bearing stability and the intended operating conditions.

Outer Ring

The outer ring has a nominal outside diameter of 59 mm.

For the corresponding NTN-SNR reference, the outer ring width is 17 mm, while the overall bearing width is 18 mm.

This distinction is important when comparing tapered roller bearings intended for transmission assemblies.

The outer ring geometry and seating arrangement should be checked before selecting a replacement.

Tapered Rollers

The rolling elements have a tapered profile and operate between matching tapered raceways.

This construction allows the bearing to accommodate radial loads together with axial loads acting in one direction.

A single row tapered roller bearing is therefore commonly used together with another bearing when a shaft must be axially supported in both directions.

Bearing Cage

The cage maintains the correct spacing between the tapered rollers and guides their movement during operation.

The specific cage material and construction of the NEUTRAL version have not been confirmed.

These characteristics should not be assumed from the corresponding NTN-SNR reference without checking the actual supplied product.

Operating Principle and Load Transmission

The EC 12625 S02H206 reference uses the operating principle of a single row tapered roller bearing.

During rotation, loads are transmitted between the inner and outer rings through the tapered rolling elements.

The geometry of the rollers and raceways allows the bearing to support combined radial and axial loads.

Unlike a conventional deep groove ball bearing, a tapered roller bearing requires particular attention to axial adjustment and the arrangement of the supporting bearings.

In mechanical transmissions, tapered roller bearings can support shafts exposed to forces generated by meshing gears.

Correct operation depends on suitable mounting fits and the required axial clearance or preload.

Incorrect adjustment may cause excessive friction, elevated operating temperatures, noise and premature raceway damage.

Alternative Designations and Reference Numbers

The bearing reference may appear in several notation formats:

• EC 12625 S02H206

• EC 12625 S02 H206

• EC.12625.S02.H206

• EC12625S02H206

• EC 12625 S02H206 NEUTRAL

• EC.12625.S02.H206 NTN-SNR

These variations can help identify the reference in catalogs and parts databases.

However, different commercial products using a similar reference should not automatically be considered identical in every technical specification.

OE Reference Numbers Associated with NTN-SNR

These numbers are associated with the NTN-SNR reference EC.12625.S02.H206.

For the NEUTRAL version, compatibility with the required OE number, bearing geometry and specific transmission must be verified before installation.

EC 12625 S02H206 vs Other Transmission Bearing Variants

EC 12625 S02H206 vs EC 12567 H206

These are separate bearing references and should not be considered identical products.

EC 12625 S02H206 has nominal dimensions of 25x59x18 mm.

EC 12567 H206 has a different bearing geometry, including a flanged arrangement with a larger outside flange diameter.

The differences in dimensions and construction must be checked against the transmission manufacturer's specifications.

EC 12625 S02H206 vs EC 40987 H206

EC 40987 H206 is another transmission bearing reference with different dimensional characteristics.

Its geometry includes a flange diameter of approximately 65.83 mm and a catalog width of 17.5 mm.

It should not be treated as a direct replacement for EC 12625 S02H206 without detailed technical verification.

EC 12625 S02H206 NEUTRAL vs NTN-SNR

The NEUTRAL product and the NTN-SNR reference may be offered under corresponding identification numbers.

However, this does not automatically confirm identical manufacturing specifications.

Before replacement, verify:

• Inner and outer ring geometry.

• Overall bearing width.

• Cage construction.

• Dimensional tolerances.

• Required axial clearance or preload.

• OE reference number.

• Compatibility with the specific transmission.

Identical nominal dimensions of 25x59x18 mm are not sufficient to establish complete interchangeability.

Applications of EC 12625 S02H206

The NTN-SNR reference EC.12625.S02.H206 is cataloged as a bearing for manual transmission applications.

The manufacturer's reference information associates it with the JC5 transmission designation.

The corresponding NTN-SNR reference is also linked to Renault OE number 7703090425.

These are documented applications of the reference bearing and should not automatically be interpreted as confirmed fitment for every NEUTRAL product.

For the NEUTRAL version, the exact transmission, OE number and bearing geometry must be checked before installation.

When repairing a manual gearbox, the transmission code and the designation of the removed bearing provide a more reliable basis for identification than the vehicle model alone.

Selection and Interchangeability

Before purchasing EC 12625 S02H206 (NEUTRAL), verify the following:

1. Complete bearing designation EC 12625 S02H206.

2. Nominal dimensions of 25x59x18 mm.

3. Single row tapered roller construction.

4. Outer ring width and geometry.

5. Any special features of the inner and outer rings.

6. Transmission identification code.

7. Required OE reference number.

8. Shaft and housing mounting arrangements.

9. Required axial clearance or preload.

10. Lubrication conditions.

11. Dimensional tolerances.

12. Compatibility with the transmission manufacturer's service documentation.

Tapered roller bearings with identical basic dimensions are not necessarily interchangeable.

In automotive transmissions, differences in ring geometry, overall bearing height and adjustment requirements may be critical.

The complete reference and the actual bearing construction should always be checked before installation.

Installation and Operating Recommendations

Preparation Before Installation

Clean the shaft, housing and all mating surfaces before installation.

Inspect the mounting surfaces for corrosion, burrs and mechanical damage.

Check that the bearing rings can be installed in accordance with the required fits.

Mounting the Bearing Rings

Mounting force must be applied directly to the bearing ring being installed with an interference fit.

Do not transmit mounting force through the tapered rollers or raceways.

Incorrect installation may damage the rolling elements and cause premature bearing failure.

The outer ring must also be correctly seated in the housing.

Axial Clearance and Preload Adjustment

Tapered roller bearings require appropriate adjustment of axial clearance or preload, depending on the bearing arrangement.

For manual transmission applications, follow the gearbox manufacturer's service procedure.

Incorrect adjustment can lead to excessive operating temperatures, abnormal noise, increased friction and premature wear.

Lubrication

Lubrication must meet the requirements of the specific transmission.

In automotive gearbox applications, bearings of this type may operate with transmission oil lubrication.

Oil grade, viscosity and filling level should be selected according to the transmission manufacturer's specifications.

Storage

Store the bearing in its original packaging in a clean, dry environment.

Protect it from moisture, contamination, vibration and mechanical damage.
