Reliable capacity for combined loads

Practical benefits

Double row Skf design: You support high radial forces and two-directional axial loads simultaneously within a very compact envelope.
Low friction polymer cage: The lightweight polyamide cage minimizes heat build-up so you maintain smooth operation at high rotational speeds.
Rigid and stable mounting: With its 30° contact angle, the bearing delivers a stiff arrangement that keeps rotating shafts precisely aligned.

In a nutshell

The right choise for

With the Skf 3303 ATN9 double row angular contact ball bearing, you accommodate heavy radial and two-directional axial loads simultaneously within a compact envelope. Thanks to its 30° contact angle, you achieve a rigid bearing arrangement that effectively resists tilting moments on rotating shafts. The low-friction, glass-fibre reinforced polyamide cage (TN9) minimizes heat build-up to maintain smooth and quiet operation at high speeds. Featuring a normal internal clearance (CN), open design, and dimensions of 17 x 47 x 22.2 mm, it is the practical solution for gearboxes, industrial pumps, and electric motors in clean, externally lubricated environments.

Key features according to our expert

Inner diameter: 17 mm
Width: 22,2 mm
Number of rows: 2
Axial clearance: CN (Normal)
Sealing (bearing): Without seals
Material (bearing seal): Not applicable
Material (cage): Plastic
Outer diameter: 47 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
