Technical Specifications - SNR 6206FT150ZZ

Temperature note: NTN-SNR specifies 150 degrees C as the maximum peak temperature for the TOPLINE FT150 range.

This does not mean that the grease will provide unlimited service life during continuous operation at 150 degrees C.

Actual operating suitability depends on rotational speed, bearing load, heat dissipation, lubrication conditions and required service life.

What Does SNR 6206FT150ZZ Mean?

6206 - Bearing Series and Dimensions

6206 identifies a single-row deep groove ball bearing from the 6200 dimensional series.

Its principal dimensions are:

• Bore diameter: 30 mm.

• Outside diameter: 62 mm.

• Width: 16 mm.

These are the standard boundary dimensions of a 6206 bearing.

However, identical dimensions do not mean that all 6206 bearing versions have identical operating characteristics.

FT150 - TOPLINE High-Temperature Version

FT150 identifies a special SNR bearing version designed for elevated operating temperatures.

The FT150ZZ construction includes:

• Design features suitable for high-temperature applications.

• Increased C3 radial internal clearance.

• Pressed steel cage.

• Special high-temperature grease.

• Maximum specified peak temperature of 150 degrees C.

The grease used in the FT150 range is based on synthetic oil and a polyurea thickener.

This is an important distinction compared with conventional 6206 bearings, which must not automatically be assumed to have equivalent lubrication characteristics.

ZZ - Metal Shields on Both Sides

ZZ indicates two metal shields, one on each side of the bearing.

The shields help reduce the entry of larger contaminants and retain lubricant inside the bearing.

They are not equivalent to contacting elastomer seals.

The ZZ design is suitable for applications requiring the protective properties of metal shields without the friction associated with contacting seal lips.

However, metal shields do not provide complete protection against liquids, fine dust or other contaminants.

C3 - Increased Radial Internal Clearance

SNR 6206FT150ZZ has C3 radial internal clearance as part of its FT150ZZ specification, even though C3 is not included as a separate suffix in the complete designation.

C3 means that the radial internal clearance is greater than normal.

This is particularly relevant in high-temperature applications because temperature differences between the bearing rings and mounting fits can reduce the operating clearance.

Nevertheless, C3 clearance must not automatically be considered suitable for every application.

SNR - NTN Group Brand

SNR is a brand within the NTN Group, a manufacturer of rolling bearings for industrial and automotive applications.

The TOPLINE range includes special bearing designs intended for operation under demanding temperature conditions.

Alternative Designations and Reference Numbers

The bearing may appear in technical catalogues, distributor listings and purchasing enquiries under the following written variations:

• SNR 6206FT150ZZ

• 6206FT150ZZ SNR

• 6206 FT150 ZZ SNR

• 6206.FT150.ZZ SNR

• 6206.FT150ZZ SNR

• NTN-SNR 6206FT150ZZ

• 6206FT150ZZ 30x62x16 mm

• SNR 6206 FT150 ZZ high-temperature bearing

• 6206FT150ZZ deep groove ball bearing

These written variations identify the FT150ZZ bearing version.

It must not be confused with 6206FT150 without the ZZ suffix.

Construction and Operating Principle of SNR 6206FT150ZZ

Single-Row Deep Groove Ball Bearing Construction

The bearing contains one row of balls operating between the raceways of the inner and outer rings.

Its construction allows it to support radial loads and axial loads in both directions, within the limits determined by the operating conditions.

The raceway geometry is characteristic of deep groove ball bearings.

The actual load capacity depends on load direction, operating speed, mounting conditions, lubrication and temperature.

Pressed Steel Cage

The manufacturer specifies a pressed steel cage.

The cage maintains appropriate spacing between the balls and guides them during operation.

It is a defined component of the FT150ZZ construction.

Polymer or brass cage specifications used in other bearing designs must not be assumed to apply to this version.

Double Metal Shielding

Metal shields are fitted on both sides of the bearing.

They help protect the rolling elements against contamination and reduce lubricant loss.

Unlike contacting elastomer seals, metal shields do not rely on continuous contact between a flexible sealing lip and the rotating ring.

This helps avoid the additional friction associated with contacting seals.

However, the shields do not make the bearing completely sealed against water, fine dust or aggressive contaminants.

High-Temperature Grease

SNR 6206FT150ZZ is factory-lubricated with grease intended for elevated operating temperatures.

According to NTN-SNR documentation, the FT150 range uses:

• Synthetic base oil.

• Polyurea thickener.

Grease service life depends on temperature, rotational speed, load and operating conditions.

A conventional general-purpose bearing grease must not automatically be considered a suitable substitute for the lubricant specified for FT150ZZ.

Increased Internal Clearance

The bearing incorporates C3 radial internal clearance.

During operation, thermal expansion and mounting fits influence the effective internal clearance.

The correct operating clearance must be considered as part of the complete bearing arrangement.

A bearing with normal clearance must not automatically be substituted for this high-temperature C3 version.

Load Ratings and Operating Speed

Basic Dynamic Load Rating C - 20.5 kN

The basic dynamic load rating is 20.5 kN.

This parameter is used when calculating bearing fatigue life under specified loading conditions.

It does not represent the maximum permissible load under all operating conditions.

Basic Static Load Rating C0 - 11.3 kN

The basic static load rating is 11.3 kN.

This parameter is relevant when assessing the risk of permanent deformation at the contact points between the balls and raceways.

Fatigue Load Limit Cu - 0.51 kN

The manufacturer specifies a fatigue load limit of 0.51 kN.

This parameter is used in bearing life calculations.

It must not be interpreted as the maximum load that the bearing can support.

Mechanical Limiting Speed - 11000 rpm

The catalogue mechanical limiting speed is 11000 rpm.

This value does not mean that the bearing can operate continuously at this speed under every load and temperature condition.

In high-temperature applications, lubrication limitations and heat dissipation must also be considered.

SNR 6206FT150ZZ vs Other Bearing Versions

6206FT150ZZ vs SNR 6206FT150

Both versions belong to the TOPLINE high-temperature range.

However, their sealing arrangements differ.

6206FT150ZZ is the metal-shielded version.

6206FT150 is the version with contacting fluoroelastomer (FKM) seals.

This difference affects contamination protection, seal friction and operating characteristics.

6206FT150ZZ vs Standard 6206ZZ

Both bearings have dimensions of 30x62x16 mm and metal shields on both sides.

However, 6206FT150ZZ is a special TOPLINE high-temperature version.

It incorporates specified C3 radial internal clearance and grease designed for elevated temperatures.

A standard 6206ZZ bearing must not automatically be used as a replacement in an application requiring FT150ZZ characteristics.

6206FT150ZZ vs 6206-2RS

Standard 6206-2RS bearings use elastomer seals on both sides.

The FT150ZZ version uses metal shields and a special high-temperature specification.

Identical boundary dimensions do not guarantee equivalent operating performance.

6206FT150ZZ vs 6206HT200ZZ

FT150ZZ and HT200ZZ belong to different temperature ranges within the TOPLINE family.

FT150ZZ is specified for peak temperatures up to 150 degrees C.

HT200ZZ is designed for peak temperatures up to 200 degrees C, with different lubrication and internal clearance specifications.

These versions must not be considered technically identical.

Can SNR 6206FT150ZZ Be Replaced by Another Manufacturer's Bearing?

A suitable replacement must match more than the dimensions of 30x62x16 mm.

It must also meet the required temperature range, shielding arrangement, internal clearance and lubrication specifications.

A conventional 6206ZZ bearing should not be substituted solely because its principal dimensions are identical.

Is a Standard 6206 Bearing Suitable for High-Temperature Applications?

A standard 6206 bearing may have the same boundary dimensions but different grease, internal clearance, cage construction or sealing materials.

These differences can be important at elevated temperatures.

The complete operating specification must be verified before selecting a replacement.

Applications of SNR 6206FT150ZZ

SNR 6206FT150ZZ is designed for applications requiring a deep groove ball bearing suitable for elevated operating temperatures.

Typical applications for this bearing class include:

• Industrial equipment operating at elevated temperatures.

Selection requires verification of actual temperature, load, speed and environmental conditions.

Installation and Operating Recommendations

Preparation Before Installation

Before installation, inspect the shaft and bearing housing for cleanliness.

The mating surfaces should be free from burrs, corrosion and mechanical damage.

Verify the required mounting fits and account for thermal expansion during operation.

Correct Application of Mounting Force

When pressing the bearing onto a shaft, apply the installation force directly to the inner ring.

When pressing the bearing into a housing, apply the installation force directly to the outer ring.

Mounting forces must never be transmitted through the balls.

Protection of ZZ Shields

Do not deform or remove the metal shields.

Damaged shields may reduce protection against contamination and affect lubricant retention.

Temperature Monitoring

In high-temperature applications, monitor operating temperature, vibration and noise.

The reduction in grease service life as temperature increases must also be considered.

Storage

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

Protect it against moisture, contamination and mechanical damage before installation.
