The NTN HTA9UA series thrust ball bearing is an angular contact bearing designed to carry 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 measuring equipment where axial rigidity and clearance control are critical. MR Accesorios Industriales sells this series in Buenos Aires, Argentina, with more than 80 years of experience in bearings and power transmission.

The HTA9UA designation reads as follows: HTA identifies the family of high-precision angular contact thrust ball bearings; the number that follows —920, 921, 922, 924, 926, 928, 930, 932— indicates the size or dimension code within the series; UA indicates a special execution, normally linked to the contact angle or the universal mounting prefix. Each complete code, such as HTA920UADB or HTA932UADB, defines an exact combination of dimensions and tolerances. To request a quote, send us the code exactly as it appears on your drawing or on the part.

These bearings are used in main 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, measuring heads and optical equipment that require controlled axial movement. In Argentine industry, you will find them in precision machining shops, automotive plants and machine tool factories. MR Accesorios Industriales sells them for replacement and new projects.

To select the correct bearing, take into account the axial load it will carry, the rotational speed and the internal clearance required by the assembly. Mounting demands extreme cleanliness, careful alignment of the raceways and a preload defined according to the spindle design. Lubrication —grease or oil— must be chosen based on temperature and speed. Adequate sealing prevents the entry of contaminants, which in this type of bearing quickly ruins precision.

As for equivalences, high-precision angular contact thrust ball bearings are identified by each manufacturer's own codes. If you bring an unidentified part or a code from another brand, at MR we will indicate the compatible alternative. There is no universal replacement table: interchangeability depends on the mounting dimensions, the contact angle and the precision class. That is why it is best to request a quote with the complete designation or with the measured dimensions.

If you need this NTN HTA9UA series thrust bearing, write to us on WhatsApp with the exact code —for example HTA920UADB— or with the dimensions of your application. At MR Accesorios Industriales we will quote you shortly and advise you so that the part arrives with the correct tolerances. We serve workshops, plants and distributors throughout the country from Buenos Aires, Argentina.
