What is a double row ball bearing?

A double-row ball bearing is a type of bearing designed to support higher loads than single-row ball bearings. These bearings have the same outside diameter and bore as single-row bearings, but are slightly wider.

Double-row ball bearings are widely used in a variety of industrial and automotive applications. They offer good load carrying capacity and high rigidity, making them suitable for applications requiring high load carrying capacity and running accuracy.

What are the different types of double-row ball bearings?

As with single-row ball bearings, there are two main types of double-row ball bearings:

• Deep groove bearings, known as the 4200 and 4300 series, which support more load than single-row ball bearings.
• Angular contact bearings, known as the 3200, 3300, 5200 and 5300 series, which correspond to two single-row angular contact ball bearings arranged in an O arrangement. Wheel hub bearings, DAC type, are also double-row angular contact ball bearings. The difference is that they have two inner rings rather than one.

Series 4200, 4300, 3200, 3300, 5200 and 5300 bearings are available sealed or non-sealed, with increased or standard clearance, and with steel or polyamide cages. DAC bearings are generally always offered sealed and with standard clearance.

How to choose a double-row ball bearing?

When choosing a double-row ball bearing, we recommend that you always fit a bearing identical to the one you had originally. To do this, you have two options: you can identify the part number on the original bearing or take its dimensions. When choosing a double-row ball bearing, we advise you to always reassemble a bearing identical to the original one. There are two ways of doing this: you can identify the part number on the original bearing, or take its dimensions. As far as dimensions are concerned, you'll need to take the inside diameter, outside diameter and thickness of the bearing.

It is also important to consider the operating conditions of the application. Factors such as load capacity, speed and temperature must be taken into account when selecting the most suitable bearing for the application. It is also important to consider factors such as size, material and lubrication to ensure reliable operation over the bearing's entire service life.
