SNR 2207 EEG15 35x72x23 mm - Sealed Self-Aligning Ball Bearing

SNR 2207 EEG15 35x72x23 mm - Sealed Self-Aligning Ball Bearing

SNR 2207 EEG15 35x72x23 mm is a double-row self-aligning ball bearing with a cylindrical bore, contact seals on both sides and a polyamide cage. It has a 35 mm bore diameter, 72 mm outside diameter and 23 mm width. The self-aligning design combines two rows of balls with a common spherical raceway in the outer ring, allowing the bearing to accommodate angular misalignment between the shaft and housing.

Technical data

What does SNR 2207 EEG15 mean?

SNR - bearing brand of NTN Europe.

2207 - basic designation identifying this size and series of double-row self-aligning ball bearing.

EE - identifies the sealed execution with seals on both sides.

G15 - identifies an execution with a polymer cage; for this specific bearing, the manufacturer specifies a polyamide cage.

The complete designation 2207 EEG15 is important for correct product identification.

A basic 2207 bearing without the additional EEG15 designation should not automatically be considered identical to the 2207 EEG15 version.

SNR 2207 EEG15 dimensions

The principal dimensions are:

35x72x23 mm

where:

• d = 35 mm - bore diameter

• D = 72 mm - outside diameter

• B = 23 mm - bearing width

These dimensions correspond to the 2207 bearing size, but the EEG15 execution must also be considered when selecting a replacement.

Self-aligning bearing construction

SNR 2207 EEG15 is a double-row self-aligning ball bearing.

Its construction includes:

• inner ring

• two rows of balls

• polyamide cage

• outer ring with a common spherical raceway

• contact seals on both sides

The spherical geometry of the outer ring raceway enables the inner ring and ball assembly to align itself relative to the outer ring.

This self-aligning capability is the fundamental construction feature that distinguishes this bearing from a conventional deep groove ball bearing.

How does the self-aligning design work?

In a bearing arrangement, small angular differences can occur between the shaft axis and housing axis.

Possible causes include:

• shaft deflection

• housing misalignment

• mounting inaccuracies

• deformation of the supporting structure

A self-aligning ball bearing is designed so that the inner ring and rolling element assembly can operate at an angle relative to the outer ring.

This allows the bearing to accommodate a degree of angular misalignment without forcing both rings into rigid axial alignment.

However, self-aligning capability should not be interpreted as the ability to compensate for unlimited installation errors or excessive shaft deflection.

Double-row ball design

SNR 2207 EEG15 contains two rows of balls.

Both rows operate against the common spherical raceway of the outer ring.

This geometry gives the bearing its self-aligning properties and differentiates the 22 series self-aligning bearing from a conventional single-row deep groove ball bearing.

EE - contact seals on both sides

The EE suffix identifies the sealed bearing execution.

SNR specifies the 2207 EEG15 with contact seals on both sides.

The seals help:

• reduce the ingress of contaminants

• protect the internal rolling contact surfaces

• retain lubricant within the bearing

This is an important functional difference compared with an open SNR 2207 bearing.

When replacing the bearing, the sealing configuration should therefore be checked rather than selecting an alternative solely from the 35x72x23 mm dimensions.

G15 - polyamide cage

The 2207 EEG15 execution uses a polyamide cage.

The cage performs several important functions:

• separates the balls

• maintains correct spacing between rolling elements

• guides the balls during bearing operation

The G15 designation should not be omitted when identifying the exact bearing execution because it forms part of the complete product designation.

SNR 2207 EEG15 vs SNR 2207

Both versions share the principal dimensions:

35x72x23 mm

However, they are not identical executions.

SNR 2207 is an open self-aligning ball bearing.

SNR 2207 EEG15 incorporates contact seals on both sides and a polyamide cage.

Therefore, the complete bearing designation should be considered when ordering or selecting a replacement rather than relying only on the base designation 2207.

SNR 2207 EEG15 vs 2207 KEEG15

The following designations should not be confused:

2207 EEG15

and

2207 KEEG15

The K suffix identifies a tapered bore version.

SNR 2207 EEG15 has a cylindrical 35 mm bore.

This difference is particularly important because cylindrical and tapered bore versions use different mounting arrangements.

The K suffix should therefore never be omitted when identifying a tapered bore bearing.

CN radial internal clearance

SNR specifies standard CN radial internal clearance for the 2207 EEG15.

CN represents the normal internal clearance range for this bearing execution.

If the bearing being replaced carries a special clearance designation such as C3, interchangeability with the CN version should not be assumed without checking the requirements of the bearing arrangement.

Why the complete designation matters

For industrial bearings, the base number alone does not always define the complete construction.

In this case:

2207 identifies the basic bearing size and series.

EEG15 provides additional information about the specific bearing execution.

Ignoring these additional characters can result in selecting a bearing with:

• different sealing

• different cage construction

• different lubrication arrangement

• different operating characteristics

For replacement purposes, the complete designation on the original bearing should always be checked.

How to select a replacement for SNR 2207 EEG15

Verify:

• full designation 2207 EEG15

• manufacturer

• self-aligning ball bearing type

• double-row construction

• 35x72x23 mm dimensions

• cylindrical 35 mm bore

• EE sealing configuration

• G15 cage execution

• required radial internal clearance

• operating load

• rotational speed

• operating temperature

• mounting arrangement

Matching 35x72x23 mm dimensions alone does not guarantee complete interchangeability.

Open, sealed, cylindrical-bore and tapered-bore variants can differ significantly in installation and operating characteristics.

OEM or application-specific cross-references should not be assumed unless independently confirmed.

Applications

SNR 2207 EEG15 belongs to the self-aligning ball bearing family intended for bearing arrangements where accommodation of angular misalignment between the shaft and housing may be required.

Its sealed construction additionally helps protect the internal rolling elements and raceways against contamination.

The exact application should nevertheless be determined from the documentation of the machine or equipment.

Without confirmed application data, the bearing should not be assigned to a specific:

• electric motor

• fan

• conveyor

• agricultural machine

• gearbox

• industrial machine

solely on the basis of its dimensions or bearing type.

Installation of SNR 2207 EEG15

Before installation, check:

• shaft condition

• housing condition

• shaft and housing tolerances

• cleanliness of mounting surfaces

• complete designation of the bearing being replaced

Mounting force should be applied to the ring being fitted with an interference fit.

Installation force should not be transmitted through the balls and raceways, as this can damage the rolling contact surfaces.

The 2207 EEG15 has a cylindrical bore and should not be installed using a mounting procedure intended for the tapered-bore 2207 KEEG15 version.
