What are the dimensions of this bearing?

The bearing has an inside diameter of 25 mm, an outside diameter of 52 mm, and a width of 18 mm.

What does the TN9 suffix indicate?

The TN9 suffix indicates a snap-type cage made of fibreglass-reinforced polyamide (plastic).

Is this deep groove ball bearing sealed?

No, this is an open bearing without seals, suitable for applications with external lubrication.

What loads can this double-row bearing handle?

It accommodates both radial and axial loads in both directions with higher load carrying capacity than a single-row bearing.

What bore type and internal clearance does this bearing have?

The bearing features a cylindrical bore and standard normal radial internal clearance (CN).

Durable rotation with Skf

Practical benefits

High radial load capacity: The double-row ball design allows you to support significantly higher radial and axial loads than single-row alternatives.
Low-friction polyamide cage: The reinforced polymer cage reduces internal friction and vibration, giving you smooth operation at high rotational speeds.
Easy cylindrical shaft fitting: With its standard 25 mm cylindrical bore, you mount the bearing directly and securely onto machine shafts.

In a nutshell

The right choise for

Handle heavy radial and axial loads with ease in demanding drivetrains using the SKF 4205 ATN9 double-row deep groove ball bearing. Designed with two rows of steel balls, it provides significantly higher load carrying capacity than single-row alternatives, making it ideal for electric motors, pumps, and gearboxes. The fibreglass-reinforced polyamide cage (TN9) minimises friction and vibration, ensuring smooth, quiet operation at high rotational speeds. With its 25 mm cylindrical bore, 52 mm outside diameter, and 18 mm width, you can mount it accurately onto standard shafts with normal clearance (CN). This unsealed, open bearing is well suited for setups with external lubrication.

Product description

Double row deep groove ball bearings correspond, in their design and operation, to a pair of single row deep groove ball bearings. They are robust in operation, requiring little maintenance, can operate at high speeds and accommodate radial and axial loads in both directions. They are slightly wider than single row bearings of the same bore and outside diameter but have a considerably higher load carrying capacity.

Versatile and robust design
High-speed capability
Accommodate high axial and radial loads in both directions
Require little maintenance
