The NTN HTA series thrust ball bearing is an angular contact bearing designed to handle axial loads in one direction, with high precision and the ability to run at high speeds. It is used in machine tool spindles, rotary tables and precision equipment where axial rigidity and clearance control are critical. MR Accesorios Industriales sells this series backed by more than 80 years in the Argentine industrial market.

The HTA series designation is read from its base code: the letters HTA identify NTN's family of angular contact thrust ball bearings, and the number that follows —as in HTA010UDB, HTA011UDB or HTA012UDB— indicates the size within the series. The UDB suffix indicates the mounting configuration: a pair of bearings matched with a defined preload, ready to install as a set. Other suffixes may indicate preload or design variants, but it is always best to confirm the full part number when requesting a quote.

These bearings are used in the spindles of milling machines, grinding machines and machining centers, where they must absorb the axial thrust of the spindle without losing precision. They also appear in coordinate tables, deep-hole drilling heads and measuring equipment. In Argentine industry they are found in precision machining shops, auto parts factories and machine tool plants that require dimensional repeatability in machining.

To select the right bearing, you must define the axial load, the rotational speed and the required rigidity. Mounting requires absolute cleanliness, careful alignment and adequate preload, since excessive or insufficient tightening affects service life. Lubrication —grease or oil— must be chosen according to the operating conditions, and sealing protects against contaminants. In UDB pairs, mounting is done with the axial clearance already set by the manufacturer.

When looking for equivalents, each manufacturer uses its own nomenclature for angular contact thrust bearings. If you have another brand's part number, the best thing is to send it along with the main dimensions —bore diameter, outer diameter and height— so we can identify the equivalent NTN reference. Not all series are dimensionally interchangeable, so technical verification is essential before replacing a part.
