What are the dimensions of this SKF angular contact ball bearing?

The bearing has a 25 mm bore diameter, a 52 mm outer diameter, and a width of 20.6 mm.

What types of loads can this double-row bearing handle?

It accommodates combined radial and axial loads in both directions, as well as tilting moments.

What does the C3 clearance designation mean?

C3 indicates greater internal clearance than normal, suitable for high operating speeds and thermal expansion.

What material is the cage made from?

The TN9 suffix denotes a glass-fibre reinforced polyamide (polymer) cage.

Does this SKF bearing include built-in seals?

No, this is an open bearing without seals and requires external lubrication.

Smooth operation with Skf bearings

Practical benefits

Double direction load capacity: You effortlessly accommodate simultaneous radial and bidirectional axial loads thanks to the double row layout with a 30° contact angle.
Low friction smooth running: The lightweight polyamide cage minimizes internal friction, helping you maintain quiet and efficient operation at high rotational speeds.
Increased thermal clearance: With dedicated C3 internal clearance, you prevent thermal binding and ensure smooth mechanical operation even under elevated operating temperatures.

In a nutshell

The right choise for

With the Skf 3205 ATN9/C3 double-row angular contact ball bearing, you ensure reliable operation under demanding combined loads. Thanks to its double-row layout and 30° contact angle, it accommodates simultaneous radial and bidirectional axial forces within a compact axial space. The lightweight glass-fibre reinforced polyamide cage reduces friction and noise, making it ideal for high-speed shafts in pumps, compressors, and gearboxes. Its larger C3 internal clearance prevents thermal binding when operating temperatures rise. Measuring 25 x 52 x 20.6 mm, this open bearing delivers smooth, efficient running in lubricated machine housings.

Key features according to our expert

Inner diameter: 25 mm
Width: 20,6 mm
Number of rows: 2
Axial clearance: C3
Sealing (bearing): Without seals
Material (bearing seal): Not applicable
Material (cage): Plastic
Outer diameter: 52 mm

Product description

Double row angular contact ball bearings correspond, in their design and operation, to a pair of single row angular contact ball bearings in a back-to-back arrangement, while requiring less axial space. They can operate at high speeds and are more suitable than deep groove ball bearings for supporting large axial forces in both directions.

High-speed capability
Accommodate relatively high radial loads, high axial loads in both directions and tilting moments
Suitable where a stiff bearing arrangement is required
Require less axial space than equivalent pair of single row angular contact ball bearings
