The NTN 5S-HTA0UA series angular contact ball bearing is a high-precision component designed to withstand combined radial and axial loads in applications where rotational accuracy is critical. It is used in machine tool spindles, measuring equipment and positioning systems that demand rigidity and repeatability. MR Accesorios Industriales sells this series in Buenos Aires, Argentina, and advises you on selecting the right configuration for your application.

The designation of this series combines several indicators. The prefix 5S indicates a special high-precision execution, while HTA identifies the angular contact series with a contact angle optimized for high speed. The 0UA block defines the internal design and the cage type, and the suffix DB indicates back-to-back tandem mounting, which provides axial rigidity in both directions. Examples such as 5S-HTA010UADB or 5S-HTA014UADB show how the central number (010, 014) encodes the bore diameter size.

These bearings are used in milling machine spindles, machining centers, grinding machines and precision lathes, as well as in measuring heads and rotary tables. In Argentine industry, they are common in the metalworking, automotive and machine tool sectors, where high rotation speed and rigidity are required. They also appear in high-end printing equipment and coordinate positioning systems.

To select the right bearing, take into account the axial and radial load, the maximum operating speed and the required rigidity. DB paired mounting requires precise fitting of the housing and shaft, with tightly controlled concentricity and perpendicularity tolerances. Lubrication can be with grease or oil, depending on speed and temperature; in high-speed spindles, oil lubrication and cooling systems are preferred. Alignment between supports is critical to avoid parasitic loads.

NTN 5S-HTA0UA series bearings can be interchanged with other brands of equivalent performance, as long as the main dimensions and the contact angle are respected. When looking for equivalents, it is essential to verify the precision (ABEC/ISO class) and the mounting type. MR Accesorios Industriales helps you find the compatible part number if you send us the code of the original part or the housing dimensions.
