NTN HSL series angular contact ball bearings are precision components designed to support 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. MR Accesorios Industriales sells this NTN line, a brand MR sells, and advises you on choosing the correct part number for your equipment.

The designation of these bearings is read in blocks. The prefix 5S indicates the cage type and surface treatment; 2LA refers to the sealing or protection design; HSL identifies the high-precision angular contact series; and the final number, as in 5S-2LA-HSL010AD, indicates the size. The suffix AD defines internal clearance or preload characteristics. Knowing each part avoids errors when ordering spare parts.

In Argentine industry, these bearings are used in milling machine, grinding machine and machining center spindles, where precision and speed are critical. They also appear in metrology equipment, rotary tables and transmission systems that require axial rigidity. Their ability to run at high revolutions makes them common in the automotive and aeronautical sectors, always in high-demand applications.

To select the correct bearing, take into account the load direction, rotational speed and lubrication type. Mounting requires precise alignment and, in many cases, pairs of bearings mounted in opposition. The 2LA seal protects against contaminants, but verify compatibility with the lubricant. Preload and internal clearance, indicated by the suffix, affect rigidity and service life. Follow the manufacturer's recommendations for adjustment.

When looking for equivalents, remember that each manufacturer uses its own nomenclature. An NTN bearing of the HSL series may have an equivalent in other brands, but the dimensions and tolerances must match exactly. Do not rely on the part number alone: compare bore, outer diameter, width and load capacity. MR Accesorios Industriales can help you identify the correct part if you send us the measurements or the original part number.

If you need spare parts for your equipment, write to us via WhatsApp with the part number or model shown on the bearing. At MR Accesorios Industriales we will quote you shortly and indicate the compatible alternative if applicable. With more than 80 years in the market, we are your partner for keeping production running.

Frequently Asked Questions

What does the 5S-2LA-HSL010AD designation mean?
The 5S prefix indicates the cage type and treatment; 2LA refers to sealing; HSL is the high-precision angular contact series; 010 indicates the size; and AD defines internal clearance or preload characteristics. Each block provides key information for selection.
How do I choose between a sealed and an open bearing?
The 2LA seal protects against contaminants and retains lubricant, ideal for dirty environments. If the equipment runs clean and at very high speeds, an open design may be better. Consider the application and consult us to define the best option.
What data do I need to request a quote for a replacement?
Send the complete part number shown on the bearing, or the bore, outer diameter and width measurements. Working conditions also help: load, speed and lubrication type. With that we will quote you shortly.
