NTN 5S-2LA-HSE9U series angular contact ball bearings are precision components designed to withstand combined radial and axial loads in a single direction. They are used in applications requiring high rotational accuracy and rigidity, such as machine tool spindles, measuring equipment and positioning systems. Their angular contact design allows a tight fit and precise control of axial clearance, making them ideal for demanding environments.

The designation of this series is interpreted in blocks: 5S indicates the presence of ceramic balls (hybrid), 2LA refers to the cage and lubrication type, HSE indicates the high-speed and precision execution, and 9U corresponds to the single-row angular contact design. Examples such as 5S-2LA-HSE910U or 5S-2LA-HSE917U show how the size number varies within the same series, maintaining the construction features.

In Argentine industry, these bearings are used in milling machine, grinding machine and machining center spindles, as well as in metrology equipment and industrial robots. They also appear in precision transmission applications where axial rigidity and high-speed rotation capability are critical. Their use is widespread in metalworking shops and production plants that require repeatability and long service life.

To select the right bearing, take into account the direction of the axial load, the type of mounting (individual, paired or tandem) and the required internal clearance. Sealing and lubrication are key: the 5S-2LA-HSE9U series usually incorporates a synthetic material cage and specific lubrication for high speed. Precise alignment of the shaft and housing, together with a proper fit, guarantee performance and prevent premature failures.

If you need to replace a bearing from another brand, we can help you find the right equivalent. Interchangeability between manufacturers is based on the main dimensions and the type of execution, but it is always advisable to verify tolerances and clearance. At MR Accesorios Industriales we advise you so that the replacement meets the requirements of your application.
