SNR 6005 FT150 25x47x12 High-Temperature Deep Groove Ball Bearing

SNR 6005 FT150 25x47x12 High-Temperature Deep Groove Ball Bearing

SNR 6005 FT150, manufacturer designation 6005FT150, is a TOPLINE single-row deep groove ball bearing measuring 25x47x12 mm, designed for applications at temperatures up to +150°C. This specific FT150 version features C3 radial internal clearance, contact seals on both sides and a pressed steel cage. It is a special high-temperature variant of the 6005 bearing and should be distinguished from standard SNR 6005 bearings and the separate 6005FT150ZZ version.

SNR 6005FT150 Dimensions

The exact principal dimensions are:

d = 25 mm - bore diameter

D = 47 mm - outside diameter

B = 12 mm - bearing width

Complete dimensions:

25x47x12 mm

Additional NTN-SNR dimensional data:

d1: 31.6 mm

D1: 42.8 mm

rs min: 0.6 mm

The 25x47x12 mm dimensions correspond to the 6005 bearing size, but dimensions alone do not identify this specific bearing configuration.

The critical additional designation is:

FT150

What Does FT150 Mean on an SNR Bearing?

FT150 identifies a special high-temperature bearing configuration in the:

SNR TOPLINE

range.

The FT150 series is designed for applications at temperatures up to:

+150°C

For this reason, the FT150 suffix is a fundamental part of the product identification.

The bearing should not be described simply as:

SNR 6005 25x47x12

because this would omit the feature that distinguishes this particular version from a standard SNR 6005 bearing.

The correct technical entity is:

SNR 6005FT150

6005 FT150 Operating Temperature

Official NTN-SNR product data specify:

Minimum operating temperature:

-30°C

Maximum operating temperature:

+150°C

The specified operating temperature range is therefore:

-30°C to +150°C

The high-temperature specification is one of the principal characteristics distinguishing the FT150 version from conventional 6005 bearing configurations.

When selecting the bearing, the actual temperature at the bearing position should be considered rather than ambient temperature alone.

Contact Seals on Both Sides

SNR 6005FT150 is equipped with:

contact seals on both sides

The seals are an integral feature of this specific FT150 configuration.

This distinguishes the bearing from open 6005 versions and from variants equipped with metal shields.

The complete configuration should therefore be identified as a:

sealed high-temperature deep groove ball bearing

6005 FT150 vs 6005 FT150ZZ

SNR lists:

6005FT150

and:

6005FT150ZZ

as different bearing configurations.

The 6005FT150 version uses:

contact seals on both sides

The 6005FT150ZZ designation identifies the shielded FT150 version.

Although both belong to the high-temperature FT150 range and share the principal 25x47x12 mm dimensions, they should not be treated as the same product.

The sealing configuration must be checked when selecting a replacement.

C3 Radial Internal Clearance

The official product specification identifies the radial internal clearance class as:

C3

C3 indicates radial internal clearance greater than Normal.

This clearance class is part of the specification of the exact:

6005FT150 SNR

bearing.

For accurate identification, the product should therefore not be reduced to the generic designation:

6005 SNR

The combination of:

6005 + FT150 + C3

provides substantially more precise technical identification.

Pressed Steel Cage

NTN-SNR specifies a:

pressed steel cage

for the 6005FT150.

The cage specification forms another confirmed construction feature of this exact bearing variant.

The key identification can therefore be summarized as:

SNR 6005FT150 + 25x47x12 mm + C3 + double contact seals + pressed steel cage + up to 150°C

Load Ratings of SNR 6005FT150

Current official NTN-SNR product data specify:

Dynamic load rating C:

10.6 kN

Static load rating C0:

5.8 kN

Fatigue load limit Cu:

0.26 kN

Coefficient f0:

14.5

These values relate directly to the current NTN-SNR product data for:

6005FT150 SNR

Load ratings from a standard 6005 bearing or from another manufacturer should not be automatically assigned to this FT150 version.

SNR 6005 FT150 Limiting Speed

The official product specification gives:

N lim = 9,100 rpm

This value is specified as the:

Mechanical Limiting Speed

for the 6005FT150.

A mechanical limiting speed should not be interpreted as a recommended continuous operating speed under every possible condition.

Actual permissible operating speed depends on the complete bearing arrangement and operating conditions, including load and temperature.

What Loads Can a 6005 FT150 Bearing Carry?

The SNR 6005FT150 is a:

single-row deep groove ball bearing

with:

radial contact

Deep groove ball bearings are primarily designed for radial loading and can also accommodate axial loading within the operating limits of the bearing arrangement.

For a specific application, bearing selection should account for the magnitude and direction of the applied loads and the required bearing life.

SNR TOPLINE FT150 Series

The 6005FT150 belongs to the:

SNR TOPLINE FT150

high-temperature bearing range.

FT150 bearings are specifically designed for applications requiring operating capability at temperatures up to:

+150°C

Within this range, the 6005FT150 provides the principal dimensions:

25x47x12 mm

This high-temperature identity should remain central to the product page to distinguish it from conventional 6005 bearings.

Applications for SNR 6005 FT150

The defining selection criterion for this bearing is its suitability for applications requiring operation at elevated temperatures up to +150°C.

NTN-SNR identifies industrial applications for the FT150 range including equipment such as:

industrial fans

electric motors

conveyor systems

The exact bearing should nevertheless be selected according to the technical requirements of the specific machine.

Parameters to verify include:

25x47x12 mm dimensions

operating temperature

radial internal clearance C3

load

speed

sealing configuration

mounting conditions

6005 FT150 vs Standard SNR 6005

The basic designation:

6005

identifies the bearing size and series.

The additional designation:

FT150

identifies the special high-temperature SNR configuration.

A standard open SNR 6005, for example, is a different product with CN clearance and a manufacturer-specified maximum operating temperature of 120°C.

The 6005FT150 has C3 clearance, contact seals on both sides and a maximum specified operating temperature of 150°C.

Therefore:

SNR 6005

and:

SNR 6005FT150

should not be treated as identical products merely because both measure 25x47x12 mm.

Can a Standard 6005 25x47x12 Replace 6005FT150?

Not based on dimensions alone.

When replacing an SNR 6005FT150, verify at least:

Dimensions - 25x47x12 mm

High-temperature FT150 configuration

Operating temperature requirement

C3 radial internal clearance

Contact seals on both sides

Cage construction

Load ratings

Speed requirements

Mounting conditions

A conventional 6005 bearing may have the same principal dimensions while differing significantly in clearance, sealing and permissible operating temperature.

6005FT150 Abutment Dimensions

Official NTN-SNR data specify:

da min: 29 mm

da max: 31.6 mm

Da max: 43 mm

ra max: 0.6 mm

These dimensions are relevant when checking the surrounding shaft and housing geometry for the bearing installation.
