Technical Specifications - SNR EC.12567.H206

Important dimensional distinction: The dimensions 25x59/65.83x17.5 mm identify the bore diameter, outer ring body diameter, flange diameter and catalogue width.

The 59 mm dimension refers to the main outer ring body, while 65.83 mm refers to the flange.

Both dimensions are essential when checking compatibility with the transmission housing.

Some online catalogue listings use rounded dimensions of 25x59/65x18 mm. The more precise values of 65.83 mm and 17.5 mm are used in the technical catalogue.

What Does SNR EC.12567.H206 Mean?

EC.12567 - Transmission Bearing Identification

EC.12567 forms part of the manufacturer's designation for a special tapered roller bearing designed for automotive gearbox applications.

It is not a conventional dimensional series designation such as 30205 or 32005.

The designation identifies a specific bearing construction and mounting geometry intended for compatible transmission assemblies.

H206 - Manufacturer Version Identification

H206 is an integral part of the complete bearing designation.

It must not be omitted when ordering the bearing or selecting a replacement.

The H206 element does not independently establish a particular internal clearance, cage material, precision class or lubricant specification.

These characteristics must be verified against the manufacturer's technical documentation when required for the application.

Confirmed OE Reference Numbers

These OE references are useful when identifying the correct bearing during manual gearbox repair.

Compatibility must be confirmed against the documentation for the specific transmission.

Construction and Operating Principle of SNR EC.12567.H206

Single-Row Tapered Roller Construction

EC.12567.H206 is a single-row tapered roller bearing.

Its rolling elements are tapered rollers operating between correspondingly shaped inner and outer ring raceways.

This construction enables the bearing to support combined radial and axial loads.

In a manual gearbox, these loads are generated during torque transmission through meshing gears.

The bearing forms part of the shaft support system and helps maintain the correct position of the rotating shaft relative to other transmission components.

Flanged Outer Ring

A characteristic feature of EC.12567.H206 is its outer ring flange with a diameter of 65.83 mm.

The main outer ring body diameter is 59 mm.

The flange forms part of the bearing's mounting geometry and must correspond to the housing design of the transmission.

Its geometry is important for correct positioning and axial location of the bearing within the gearbox assembly.

For this reason, a standard tapered roller bearing with a 25 mm bore and a 59 mm outside diameter must not automatically be considered a suitable replacement.

Inner Ring and Tapered Rollers

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

The tapered rollers operate between the raceways, transmitting loads through rolling contact.

Their geometry allows the bearing to accommodate the combined loading conditions found in transmission mechanisms.

The actual permissible operating loads depend on the bearing specifications, mounting arrangement and the design of the complete shaft support system.

Radial and Axial Load Transmission

A single-row tapered roller bearing can support radial loads and axial loads in one direction.

The direction of axial load support depends on the orientation of the bearing.

In a gearbox, axial clearance or preload is determined by the design of the complete shaft support arrangement.

These settings must be established according to the service documentation for the JR5 transmission.

They must not be selected solely on the basis of the bearing's principal dimensions.

Lubrication Within the Gearbox

EC.12567.H206 is intended for installation inside a manual transmission.

Lubrication conditions depend on the gearbox design and the vehicle manufacturer's specifications.

The lubricant type, viscosity and service requirements must be determined from the documentation for the specific transmission.

An arbitrary grease specification or lubrication interval should not be assigned to this bearing.

Applications of SNR EC.12567.H206

The manufacturer classifies EC.12567.H206 as a tapered roller bearing for passenger car manual transmissions.

A confirmed catalogue application is the JR5 gearbox family.

Selected Renault Applications

NTN-SNR catalogue information identifies applications in selected versions of:

• Renault Clio II

• Renault Laguna II

• Renault Megane II

• Renault Scenic II

• Renault Thalia / Symbol

These vehicle families do not represent universal compatibility with every engine, model year or transmission version.

The exact gearbox code and OE reference must be checked before purchasing.

Why Gearbox Identification Matters

Different transmissions may be installed within the same vehicle model family.

Even when two vehicles have the same engine or similar production years, their gearbox bearings may differ.

For reliable identification, compare the gearbox code, OE reference and physical bearing construction.

The vehicle model name alone is not sufficient to establish compatibility.

SNR EC.12567.H206 vs Other Bearing Versions

EC.12567.H206 vs SNR EC.40987.H206

Both bearings appear in NTN-SNR transmission bearing catalogues and share the same principal catalogue dimensions.

EC.12567.H206 and EC.40987.H206 must not automatically be treated as interchangeable bearings.

Although their principal catalogue dimensions are identical, they have different manufacturer designations and associated OE references.

Before considering substitution, verify the ring geometry, mounting position and technical requirements of the specific gearbox.

EC.12567.H206 vs SNR EC.12625.S02.H206

EC.12625.S02.H206 is a separate NTN-SNR catalogue bearing.

Its principal dimensions are 25x59x18 mm.

Differences in designation, geometry and dimensions require verification before it can be considered as a possible replacement.

EC.12567.H206 vs Standard 25x59 mm Tapered Roller Bearings

A conventional tapered roller bearing with dimensions similar to EC.12567.H206 may have a different outer ring geometry.

The absence of the required 65.83 mm flange may prevent correct installation in the transmission housing.

Matching the 25 mm bore and 59 mm outer ring body diameter does not guarantee interchangeability.

Selection and Interchangeability of SNR EC.12567.H206

Before ordering, verify the following:

1. Complete manufacturer designation EC.12567.H206.

2. SNR manufacturer identification.

3. Renault OE reference 7701645978 or 7703090414.

4. JR5 gearbox identification code.

5. Bore diameter of 25 mm.

6. Outer ring body diameter of 59 mm.

7. Flange diameter of 65.83 mm.

8. Catalogue width of 17.5 mm.

9. Outer ring and flange geometry.

10. Bearing mounting position.

11. Direction and magnitude of axial loads.

12. Required axial clearance or preload.

13. Compatibility with the transmission service documentation.

14. Shaft and housing fits.

15. Transmission lubrication requirements.

Can EC.12567.H206 Be Replaced by Another Manufacturer's Bearing?

A replacement must match more than the principal dimensions.

The flange geometry, raceway construction and mounting requirements must also be compatible.

The most important checks are the OE reference and the specific gearbox identification.

A replacement should not be selected solely because it has dimensions of 25x59/65.83x17.5 mm.

How to Identify the Correct Gearbox Bearing

For gearbox repair, compare:

• The complete designation on the removed bearing.

• The vehicle manufacturer's OE reference.

• The gearbox identification code.

• The physical dimensions.

• The outer ring flange geometry.

• The relevant transmission service documentation.

This helps prevent incorrect selection when several bearing versions are used within the same vehicle family.

Installation and Operating Recommendations

Preparation Before Installation

Before mounting, clean the shaft and bearing housing.

Inspect the mating surfaces for wear, corrosion, burrs and mechanical damage.

Verify the required shaft and housing fits.

Correct Application of Mounting Force

When pressing a bearing ring into position, apply the installation force directly to the ring being fitted.

Do not transmit mounting force through the tapered rollers.

Incorrect force application may damage the raceways or rolling elements before the transmission is returned to service.

Flange Positioning

The outer ring flange must be correctly seated in the transmission housing.

Verify that the bearing is installed in the intended orientation and that the flange matches the housing geometry.

Axial Clearance and Preload

Axial clearance or preload must be adjusted according to the service instructions for the specific JR5 transmission.

Incorrect adjustment may cause excessive operating temperature, noise, premature wear or inadequate shaft support.

Do not use generic preload values taken from another gearbox design.

Lubrication and Storage

Lubrication must comply with the transmission manufacturer's requirements.

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

Protect the raceways, rolling elements and mounting surfaces against contamination and damage.
