Double-row angular contact ball bearing

TIMKEN 3206 ATN1/2RSC3 belongs to the double-row angular contact ball bearing family.

Unlike a conventional single-row deep groove ball bearing, an angular contact bearing has raceway geometry designed so that the load is transmitted between the raceways and balls at a defined contact angle.

The two-row arrangement enables the bearing to accommodate:

radial loads

together with:

axial loads acting in both directions.

This makes the double-row design useful where a rotating shaft requires radial support combined with axial location in both directions.

30° contact angle

TIMKEN specifies a:

30° contact angle

for the exact 3206 ATN1/2RSC3 reference.

The contact angle is an important characteristic of an angular contact ball bearing because it affects the relationship between its radial and axial load-carrying capabilities.

For this reason, a 3206 double-row angular contact bearing should not be treated as equivalent to a conventional deep groove ball bearing simply because some dimensions may appear similar.

What does 3206 mean?

3206 identifies the bearing series and size.

For this TIMKEN double-row angular contact ball bearing, the principal dimensions are:

30x62x23.8 mm

The 3206 designation should be considered together with all suffixes because different 3206 versions can differ in sealing, cage design and internal clearance.

What does ATN1 mean?

For the exact:

3206 ATN1/2RSC3

TIMKEN specifies:

cage type – molded

and:

cage material – nylon.

The ATN1 configuration therefore uses a molded nylon cage.

This is an important construction feature when comparing the bearing with other 3206 variants that may use a different cage design or material.

The complete suffix should not be omitted when an exact technical replacement is required.

What does 2RS mean?

TIMKEN identifies the 3206 ATN1/2RSC3 version as having:

contact seals.

The 2RS part of the designation indicates sealing on both sides of the bearing.

The seals help protect the internal rolling system and lubricant from external contamination.

This version should be distinguished from shielded variants such as:

3206 ATN1/ZZC3

where ZZ identifies metal shields rather than contact seals.

What does C3 mean?

The suffix:

C3

specifies increased internal clearance compared with normal internal clearance.

This is an important technical feature of the exact:

3206 ATN1/2RSC3

reference.

A standard-clearance 3206 bearing should therefore not automatically be considered an equivalent replacement for a C3 version solely because the basic dimensions are identical.

Required internal clearance depends on the design and operating conditions of the bearing arrangement, including fits and operating temperature.

Load ratings of TIMKEN 3206 ATN1/2RSC3

TIMKEN specifies the following ratings for this exact reference:

These values relate specifically to the TIMKEN 3206 ATN1/2RSC3 reference and can therefore be used when identifying this exact bearing.

3206 ATN1/2RSC3 vs 3206 ATN1/2RS

Both versions share the basic:

30x62x23.8 mm

dimensions and use the 2RS sealing configuration.

The important difference is the internal clearance.

3206 ATN1/2RS – version without the C3 suffix

3206 ATN1/2RSC3 – C3 increased internal clearance

Therefore, the C3 suffix is technically significant and should remain in the product designation when selecting a replacement.

3206 ATN1/2RSC3 vs 3206 ATN1/ZZC3

These bearings can share the same basic size and C3 clearance but differ in their closure system:

2RS – contact seals on both sides

ZZ – metal shields on both sides

The two versions should therefore not be treated as identical.

The sealing arrangement can influence protection against contamination, friction and permissible operating conditions.

Radial and axial load capability

The double-row angular contact construction allows TIMKEN 3206 ATN1/2RSC3 to accommodate combined radial and axial loads.

The bearing can support axial loading in both directions, making it suitable for bearing arrangements where the shaft must be located axially in both directions.

The actual permissible load in a specific installation depends on the operating conditions and bearing arrangement.

How to select a replacement for 3206 ATN1/2RSC3

When comparing a bearing from another manufacturer, do not use the 30x62x23.8 mm dimensions alone.

Verify at least:

• double-row angular contact construction,
• bore diameter 30 mm,
• outside diameter 62 mm,
• width 23.8 mm,
• contact angle,
• C3 internal clearance,
• contact seals on both sides,
• cage design and material,
• dynamic load rating,
• static load rating,
• permissible operating speed,
• mounting and fit requirements.

Identical dimensions alone do not guarantee complete technical interchangeability.

Typical applications

Double-row angular contact ball bearings are used in rotating assemblies where combined radial and axial loads must be accommodated within a compact bearing arrangement.

Depending on the machine design, this bearing type can be found in:

gearboxes, pumps, compressors, industrial drives, machinery and other rotating mechanical assemblies.

Suitability of the exact TIMKEN 3206 ATN1/2RSC3 for a specific machine must be determined from the required loads, speed, temperature, fits, lubrication and environmental conditions.
