What are the dimensions of this angular contact ball bearing?

The bearing has a 20 mm bore diameter, a 47 mm outside diameter, and a 20.6 mm width.

What loads can the SKF 3204 ATN9 accommodate?

With its double-row design and 30° contact angle, it supports high radial loads and axial loads in both directions.

Is this ball bearing sealed?

No, this is an open bearing without seals, allowing lubrication directly within your application.

What does the TN9 designation indicate?

TN9 indicates a cage made from glass-fibre reinforced polyamide (plastic).

What internal clearance does this bearing have?

This bearing features standard internal clearance (designated as CN).

High load stability with Skf engineering

Practical benefits

Dual direction axial capacity: The double row angular contact design lets you support combined radial and bidirectional axial loads in tight spaces.
Smooth high speed operation: The lightweight polyamide cage minimizes friction so you can maintain high rotational speeds efficiently.
High bearing arrangement rigidity: Designed with a 30° contact angle, you achieve superior resistance against tilting moments during heavy loads.

In a nutshell

The right choise for

With the Skf 3204 ATN9 double-row angular contact ball bearing, you ensure maximum stability and reliable load support in compact machine designs. This precision bearing features a 20 mm bore, a 47 mm outside diameter, and a 20.6 mm width. Thanks to its double-row construction and 30° contact angle, it accommodates heavy radial loads alongside bidirectional axial forces while effectively resisting tilting moments. The lightweight polyamide cage minimizes friction at high rotational speeds. As an open bearing with standard clearance (CN), it is built for dependable performance in pumps, gearboxes, compressors, and electric motors.

Key features according to our expert

Inner diameter: 20 mm
Width: 20,6 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
