When you need a bearing that can handle radial and axial loads in both directions, the double row angular contact ball bearing is a solid choice. Its two rows of balls at opposing contact angles let it manage tilting moments that a single row deep groove ball bearing cannot. This makes it suitable for machine tool spindles, gearboxes, and transmission equipment where precision and load capacity matter. MR Industrial Accessories LLC supplies the NTN S series.

Reading the NTN S series code is straightforward: the first digits give the size, and the final S tells you it is a double row angular contact bearing. For instance, the 5200S has a 10 mm bore, the 5201S a 12 mm bore, the 5202S a 15 mm bore, the 5203S a 17 mm bore, the 5205S a 25 mm bore, the 5206S a 30 mm bore, and the 5207S a 35 mm bore. This naming system helps you quickly match the bore size to your equipment.

These bearings are found in demanding applications. They appear in machine tool main spindles where rigidity and precision are critical. They also serve in gearboxes and gear cases that must withstand combined loads, in process centrifugal pumps, in compressors, and in belt drive equipment. Because they can handle axial loads in both directions, they are well-suited to assemblies where the load direction changes during operation.

Selecting the right S series bearing involves considering the radial and axial loads it will support, along with speed and lubrication conditions. Check the internal clearance carefully: too much can cause vibrations and noise, while too little can lead to overheating. Mounting requires precise alignment between shaft and housing; any misalignment will accelerate wear. Use the lubrication recommended by the manufacturer, whether grease or oil, to ensure a long service life.

When replacing a bearing, keep in mind that double row angular contact bearings from different brands may vary in dimensions and load capacity. 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 information, we can indicate a compatible alternative or quote the exact code you need.
