EC 12625 S02 H206 SNR 25x59x18 mm - Single Row Tapered Roller Bearing

Technical Specifications - EC 12625 S02 H206 SNR

The dynamic load rating C, static load rating C0, fatigue load limit Pu, limiting speed, bearing mass, cage material and precision class are not included because these parameters have not been reliably confirmed for this exact bearing designation.

What Does EC 12625 S02 H206 Mean?

SNR - Bearing Manufacturer

SNR is a rolling bearing brand belonging to NTN-SNR, a manufacturer of bearing solutions for industrial machinery, automotive systems and mechanical transmissions.

The EC 12625 S02 H206 reference identifies a specific tapered roller bearing configuration used in transmission applications.

EC 12625 - Basic Bearing Reference

EC 12625 forms the main part of the manufacturer's bearing designation.

It identifies a particular tapered roller bearing design with nominal dimensions of 25x59x18 mm.

The reference must not be treated as interchangeable with every tapered roller bearing of the same basic dimensions.

Differences in ring geometry, overall width and internal construction may affect installation and operating conditions.

S02 H206 - Specific Bearing Version

S02 H206 is an integral part of the complete bearing designation.

These elements identify a particular catalog version and must be retained when ordering or selecting a replacement.

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

They should therefore not be interpreted as verified specifications for internal clearance, cage material, precision class, heat treatment or lubrication.

Construction of EC 12625 S02 H206 SNR

Inner Ring

The inner ring has a nominal bore diameter of 25 mm.

Its tapered raceway provides the rolling contact surface for the tapered rollers.

The inner ring is mounted on a correctly dimensioned shaft journal.

Proper shaft fit is essential for stable bearing positioning and correct operating conditions.

Outer Ring

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

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

The overall bearing width is 18 mm.

When identifying a replacement transmission bearing, the complete geometry of the outer ring must be checked rather than relying solely on its outside diameter.

Tapered Rollers

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

This construction enables the bearing to accommodate radial loads and axial loads acting in one direction.

In arrangements requiring axial support in both directions, tapered roller bearings are commonly installed in an appropriately configured pair.

Bearing Cage

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

The exact cage material and construction for EC 12625 S02 H206 must be confirmed using the manufacturer's technical documentation.

Operating Principle and Load Transmission

The EC 12625 S02 H206 SNR bearing operates through rolling contact between tapered rollers and the raceways of the inner and outer rings.

Unlike ball bearings, which generally have point contact between rolling elements and raceways, tapered roller bearings use line contact.

This geometry allows the bearing to accommodate combined radial and axial loads.

In mechanical transmissions, shafts are exposed to forces generated by the engagement of gears.

Tapered roller bearings can provide the necessary support when selected and arranged according to the transmission design.

An important operating requirement is the correct adjustment of axial clearance or preload.

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

Alternative Designations and Reference Numbers

The bearing may be identified using the following notation variants:

• EC 12625 S02 H206 SNR

• SNR EC 12625 S02 H206

• EC.12625.S02.H206

• EC 12625 S02H206

• EC12625S02H206

• NTN-SNR EC.12625.S02.H206

These notation variants refer to the same catalog reference format.

When purchasing a replacement bearing, the complete manufacturer designation should be checked against the original component and technical documentation.

Associated OE Reference Numbers

These OE numbers are associated with the EC.12625.S02.H206 reference.

Compatibility must be confirmed for the specific vehicle and transmission before installation.

EC 12625 S02 H206 SNR vs Other Transmission Bearing Variants

EC 12625 S02 H206 vs EC 12567 H206

Both references belong to the category of transmission bearings, but they are not identical products.

EC 12625 S02 H206 has nominal dimensions of 25x59x18 mm.

EC 12567 H206 has different geometric characteristics, including a flanged configuration with a larger outside flange diameter.

The two references should not be considered automatically interchangeable.

EC 12625 S02 H206 vs EC 40987 H206

EC 40987 H206 is a separate 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.

These differences must be considered when identifying the correct bearing for a transmission.

EC 12625 S02 H206 SNR vs NEUTRAL Versions

Bearings offered under the EC 12625 S02 H206 reference may also be available with a NEUTRAL commercial designation.

However, identical reference numbers do not automatically confirm identical manufacturers or performance specifications.

Before selecting an alternative version, verify:

• Inner and outer ring dimensions.

• Raceway geometry.

• Overall bearing width.

• Cage construction.

• Manufacturing tolerances.

• Axial clearance or preload requirements.

• OE reference compatibility.

Applications of EC 12625 S02 H206 SNR

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

It is associated with the JC5 transmission designation and Renault OE reference 7703090425.

In this application, the bearing supports a transmission shaft exposed to radial and axial forces generated during gearbox operation.

Correct bearing selection requires identification of the transmission code and confirmation of the original bearing reference.

Similar vehicle models or gearbox families may use different bearing versions.

For this reason, selection based only on the vehicle model is not sufficient.

Bearing Selection and Interchangeability

Before purchasing EC 12625 S02 H206 SNR, verify:

1. Complete manufacturer designation.

2. Bore diameter of 25 mm.

3. Outside diameter of 59 mm.

4. Overall width of 18 mm.

5. Inner and outer ring geometry.

6. Raceway configuration.

7. Transmission identification code.

8. Required OE reference number.

9. Shaft and housing fits.

10. Required axial clearance or preload.

11. Lubrication conditions.

12. Transmission manufacturer's service requirements.

Identical nominal dimensions do not guarantee complete interchangeability between tapered roller bearings.

In manual transmissions, differences in ring geometry and overall bearing height may affect shaft positioning and bearing adjustment.

The complete designation and construction must therefore be verified 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.

Ensure that the bearing rings can be installed according to the specified fits.

Mounting the Bearing Rings

Apply mounting force directly to the ring being installed with an interference fit.

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

Incorrect mounting procedures can damage the rolling contact surfaces and reduce bearing service life.

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 result in excessive operating temperatures, increased friction, abnormal noise and premature bearing damage.

Lubrication

Lubrication must comply with the requirements of the specific transmission.

In manual 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 and mechanical damage.
