NTN 5S-2LA-HSL9U series angular contact ball bearings are precision components designed to support combined radial and axial loads in applications where rotational accuracy is critical. Their angular contact design allows paired mounting to achieve high rigidity. They are used in machine tool spindles, measuring equipment and high-speed systems. At MR Accesorios Industriales we quote them with the complete designation you need.

The 5S-2LA-HSL9U series designation is interpreted in blocks. The prefix 5S indicates the ball material, ceramic, which reduces weight and thermal expansion. The code 2LA refers to the cage and lubrication type. The letters HSL identify the high-speed angular contact series, and the final number, as in 5S-2LA-HSL910U or 5S-2LA-HSL917U, indicates the size. The final U corresponds to an internal design variant. Learn more about this nomenclature by consulting MR.

These bearings are used in spindles of milling machines, grinding machines and machining centers, where speed and precision are decisive. They are also present in metrology equipment, precision drill heads and positioning systems. In Argentina, the automotive, aerospace and machine tool sectors demand this series for replacements that require tight tolerances. MR Accesorios Industriales sells the NTN line for these applications.

To select the correct bearing, take into account the mounting arrangement: these bearings are installed in pairs and preloaded according to the required axial clearance. Proper lubrication, with grease or oil, and sealing, if the environment has contaminants, are key factors. Housing alignment and cleanliness during mounting prevent premature failures. If you need assistance, our technical team will guide you.

NTN angular contact bearings can be interchanged with those of other brands that follow the same dimensional nomenclature. When looking for a replacement, verify the main dimensions and the contact angle, and consider the load and speed conditions. Interchangeability between manufacturers is possible when these specifications are respected. If you have doubts, send us the original part number and we will indicate the equivalent.
