What are the dimensions of this ball bearing?

This bearing has a 17 mm inside diameter, a 40 mm outside diameter, and a width of 16 mm.

Does this SKF bearing have seals?

No, this is an open bearing without seals.

What is the benefit of a double-row design?

The double-row setup offers significantly higher load ratings for radial and axial forces than a single-row bearing.

What material is used for the cage?

The cage (indicated by the TN9 suffix) is made of non-metallic polymer (polyamide).

What type of bore does this bearing feature?

It features a cylindrical bore for direct mounting onto a 17 mm shaft.

Reliable load handling with Skf bearings

Practical benefits

Higher radial and axial capacity: The double-row design lets you support significantly higher combined loads in both directions compared to single-row bearings.
Smooth running at high speeds: The lightweight polyamide cage minimizes friction so you achieve stable, efficient rotation in demanding machinery.
Simple and accurate shaft mounting: Featuring a standard 17 mm cylindrical bore, you can fit the bearing directly and seamlessly into your assembly.

In a nutshell

The right choise for

With the Skf 4203 ATN9 double-row deep groove ball bearing, you ensure reliable power transmission under heavy operating loads. Thanks to its dual row of steel balls, it handles significantly higher combined radial and axial forces than a single-row bearing, making it an excellent choice for electric motors, gearboxes, and pumps. The lightweight polyamide cage (TN9) reduces internal friction, delivering smooth and quiet running even at high rotational speeds. Featuring compact 17X40X16 mm dimensions and a standard 17 mm cylindrical bore, this open bearing mounts quickly and accurately onto your shaft.

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
