What are the dimensions of this SKF ball bearing?

This bearing has a 40 mm inside diameter, an 80 mm outside diameter, and a width of 23 mm.

Is this bearing sealed or open?

This is an open bearing without integrated seals.

What radial internal clearance does this bearing have?

It features normal radial internal clearance (designated as CN).

What material is the cage made of?

The cage of this bearing is made of high-grade plastic (polyamide).

What is the main benefit of a double-row deep groove ball bearing?

The double row of balls provides significantly higher load-carrying capacity than a single-row bearing.

Higher load capacity with 4208 ATN9

Practical benefits

Double row ball design: You support heavier radial and axial loads reliably thanks to the robust double row steel construction.
Low friction polyamide cage: The lightweight polymer cage minimizes internal friction, letting you achieve smooth performance at high speeds.
Simple cylindrical shaft mounting: With its 40 mm cylindrical bore and open design, you easily install and lubricate the bearing.

In a nutshell

The right choise for

With the Skf 4208 ATN9 double-row deep groove ball bearing, you gain exceptional load capacity in compact assemblies. When radial space is too limited for a larger single-row bearing, the double row of steel balls reliably handles heavy radial and combined loads on a 40 mm shaft. The lightweight polyamide cage reduces internal friction, delivering smooth and quiet operation at high rotational speeds. Featuring a cylindrical bore and an open design, this bearing allows straightforward mounting and lubrication in gearboxes, electric motors, pumps, and industrial machinery.

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
