SKF 6205 TN9/C3 25x52x15 mm - Deep Groove Ball Bearing

SKF 6205 TN9/C3 25x52x15 mm - Deep Groove Ball Bearing

SKF 6205 TN9/C3 is a single-row deep groove ball bearing with dimensions of 25x52x15 mm. It belongs to the 6200 series and has a 25 mm bore, 52 mm outside diameter and 15 mm width. The TN9 suffix identifies a glass fibre reinforced polyamide 66 cage, rolling element centred, while C3 specifies radial internal clearance greater than Normal.

Technical data

What does SKF 6205 TN9/C3 mean?

The complete designation 6205 TN9/C3 identifies a specific configuration of an SKF deep groove ball bearing.

6205 - single-row deep groove ball bearing in the 6200 series with a 25 mm bore and principal dimensions of 25x52x15 mm.

TN9 - injection moulded cage made from glass fibre reinforced polyamide 66, rolling element centred.

C3 - radial internal clearance greater than Normal.

Both suffixes are technically significant. SKF 6205 TN9/C3 should not automatically be considered identical to 6205, 6205/C3, 6205 TN9 or other 6205 variants.

SKF 6205 TN9/C3 construction

SKF 6205 TN9/C3 is a single-row deep groove ball bearing.

Its construction includes:

• inner ring

• outer ring

• balls

• TN9 polyamide cage

The deep raceway grooves enable the bearing to accommodate primarily radial loads. The deep groove ball bearing design can also accommodate axial loads in both directions within the limits determined by the bearing configuration and operating conditions.

The designation does not contain a suffix identifying seals or metal shields, so this product is an open bearing version.

What does C3 clearance mean?

C3 specifies radial internal clearance greater than the Normal clearance range.

C3 does not mean that the bearing has higher accuracy or is universally better than a bearing with Normal clearance. It identifies a specific internal clearance range selected according to the operating requirements of the bearing arrangement.

A greater initial internal clearance can be required when mounting conditions, interference fits or thermal effects reduce the operating clearance.

A C3 bearing should therefore not automatically be replaced with a Normal clearance bearing without checking the requirements of the application.

What does the TN9 cage mean?

In SKF nomenclature, TN9 identifies an injection moulded cage made from glass fibre reinforced polyamide 66 and centred on the rolling elements.

The cage material and design form part of the complete bearing specification. A 6205 TN9/C3 should therefore not automatically be considered technically identical to a 6205 bearing equipped with another cage design.

When selecting an alternative bearing, the operating conditions and suitability of the cage material must also be considered.

Alternative designations and search references

Natural reference formats include:

• SKF 6205 TN9/C3

• 6205 TN9/C3 SKF

• SKF 6205 TN9 C3

• 6205 TN9 C3 SKF

• SKF 6205TN9/C3

• SKF 6205 TN9/C3 25x52x15

• SKF 6205 TN9/C3 25x52x15 mm

• SKF 6205 TN9 C3 bearing

For technical identification, the complete designation 6205 TN9/C3 should be retained because both TN9 and C3 define specific characteristics of the bearing.

SKF 6205 TN9/C3 vs other 6205 variants

6205 TN9/C3 vs 6205 TN9

Both versions can use the TN9 cage, but the C3 suffix specifies radial internal clearance greater than Normal. The difference in internal clearance must not be ignored when selecting a replacement.

6205 TN9/C3 vs 6205/C3

Both designations specify C3 radial internal clearance. However, TN9 additionally identifies the cage material and design.

6205 TN9/C3 vs sealed or shielded 6205 bearings

Sealed or shielded 6205 bearings may have the same principal dimensions of 25x52x15 mm but differ in closure design, contamination protection, lubricant retention and operating characteristics.

Identical dimensions do not automatically mean complete technical interchangeability.

How to select SKF 6205 TN9/C3

Before purchasing or replacing this bearing, verify:

• complete designation 6205 TN9/C3

• SKF manufacturer if specifically required

• dimensions 25x52x15 mm

• required C3 radial internal clearance

• required TN9 cage

• open bearing design

• radial and axial loads

• rotational speed

• operating temperature

• lubrication conditions

• shaft and housing fits

• requirements of the specific bearing arrangement

A replacement bearing should not be selected solely on the basis of its 25x52x15 mm dimensions.

Applications

SKF 6205 TN9/C3 is a deep groove ball bearing intended for rotating bearing arrangements where a single-row deep groove design, C3 radial internal clearance and a TN9 cage are appropriate for the operating requirements.

The designation alone does not confirm installation in any specific motor, gearbox, pump, machine or vehicle.

For replacement purposes, selection should be based on the complete designation of the original bearing and the technical requirements of the equipment.

Installation and operation

Keep the bearing, shaft, housing and mounting tools clean during installation.

Mounting force should be applied directly to the ring being installed with an interference fit. Force should not be transmitted through the balls and raceways, as this can damage the bearing.

For SKF 6205 TN9/C3, both the TN9 cage material and C3 internal clearance must be considered in relation to the operating conditions. The actual operating clearance after installation can differ from the initial clearance of the unmounted bearing.

As an open bearing, lubrication and contamination protection must be provided according to the requirements of the bearing arrangement.

FAQ

What are the dimensions of SKF 6205 TN9/C3?

SKF 6205 TN9/C3 has a 25 mm bore diameter, 52 mm outside diameter and 15 mm width. The correct dimensions are 25x52x15 mm.

Is SKF 6205 25x52x12 mm?

No. The principal dimensions of a 6205 bearing are 25x52x15 mm. The originally supplied 25x52x12 mm dimension does not correspond to the 6205 size.

What does TN9 mean in SKF 6205 TN9/C3?

TN9 identifies an injection moulded cage made from glass fibre reinforced polyamide 66 and centred on the rolling elements.

What does C3 mean?

C3 means that the bearing has radial internal clearance greater than the Normal clearance range.

Are SKF 6205 TN9/C3 and 6205/C3 the same bearing?

They should not automatically be considered identical. Both specify C3 clearance, but TN9 additionally identifies the cage material and design.

Can C3 be replaced with Normal clearance?

Not automatically. The required internal clearance depends on factors including fits, temperature and operating conditions. If the application specifies C3, changing the clearance class should be technically verified.

Is SKF 6205 TN9/C3 sealed?

No sealing or shielding suffix is included in the supplied designation. SKF 6205 TN9/C3 therefore identifies an open bearing configuration.

Can a 6205 bearing from another manufacturer replace SKF 6205 TN9/C3?

Another 6205 bearing can have the same 25x52x15 mm dimensions, but complete interchangeability requires verification of C3 clearance, cage design, closure and all other parameters required by the application.
