The double row angular contact ball bearing is a component designed to support radial and axial loads in both directions. Its construction with two rows of balls at opposing contact angles allows it to handle tilting moments, something a single row deep groove ball bearing cannot match. It is used in applications where precision and load capacity are critical, such as machine tool spindles, gearboxes and transmission equipment. MR Accesorios Industriales sells the NTN S series.

The NTN S series designation is read directly: the first digits indicate the size and the final letter S indicates the double row angular contact configuration. For example, the 5200S has a bore diameter of 10 mm, the 5201S of 12 mm, the 5202S of 15 mm, the 5203S of 17 mm, the 5205S of 25 mm, the 5206S of 30 mm and the 5207S of 35 mm. This nomenclature allows you to quickly identify the bore size and select the right bearing for your equipment.

In Argentine industry, these bearings are used in a wide variety of applications. They are present in machine tool main spindles, where rigidity and precision are essential. They are also found in gearboxes and gear cases that must withstand combined loads, in process centrifugal pumps, in compressors and in belt drive equipment. Their ability to handle axial loads in both directions makes them ideal for assemblies where the load direction changes during operation.

To correctly select an S series double row bearing, take into account the radial and axial load it will support, as well as the speed and lubrication conditions. It is essential to verify the correct internal clearance for your application: excessive clearance can generate vibrations and noise, while insufficient clearance can cause overheating. Mounting must be done with precise alignment between shaft and housing; any misalignment accelerates wear. Lubrication, whether with grease or oil, must be the one recommended by the manufacturer to ensure a long service life.

Regarding equivalences and interchangeability, double row angular contact bearings from different brands may differ in dimensions and load capacity. If you need to replace an existing bearing, the safest approach is to send us the complete code engraved on the part or the main dimensions (bore, outer diameter and width). With that data, at MR Accesorios Industriales we indicate the compatible alternative or quote the exact code you need.
