The NTN 5S-2LA-HSF0 series angular contact ball bearing is a precision component designed to carry combined radial and axial loads in applications requiring high rotational accuracy. It is used in machine tool spindles, grinding heads and measuring equipment where rigidity and repeatability are critical. MR Accesorios Industriales sells this line backed by more than 80 years in the Argentine industrial market.

The 5S-2LA-HSF0 series designation is read in blocks: the prefix 5S identifies the high-precision execution with ceramic balls and steel rings for high speed; 2LA indicates the cage type and contact angle; HSF corresponds to the spindle bearing series with adjusted preload; and 0 is the dimension code. Examples such as 5S-2LA-HSF010AD and 5S-2LA-HSF011AD show the progression of the bore diameter. The AD suffix indicates an internal design variant, such as preload or axial clearance.

These bearings are used in main spindles of machining centers, CNC lathes, grinding machines and boring machines. They are also found in high-speed milling heads, precision electric motor shafts and metrology equipment. In Argentina, the automotive, aerospace, machine tool and capital goods sectors turn to this series when they need to combine axial rigidity with high rotational speeds and low friction.

To select the correct bearing, take into account the axial and radial load, the maximum operating speed and the type of lubrication. Mounting requires precise alignment and adequate preload, which can be adjusted by means of bearing pairs in back-to-back or face-to-face arrangement. Sealing and lubrication are critical: in high-speed applications, oil or high-performance grease lubrication is recommended. The synthetic cage and the angular contact optimize thermal behavior.

NTN bearings in this series can be interchanged with equivalent products from other precision brands, provided dimensions, tolerances and load capacity are verified. Interchangeability is not automatic: the contact angle, cage type and internal clearance must be compared. To find the correct equivalent, it is essential to know the complete code and the operating conditions. MR Accesorios Industriales advises you on the selection.
