For machine tool spindles, measuring systems and positioning equipment, the NTN HSL series delivers the rigidity and rotational accuracy that combined radial and axial loads in one direction demand. This angular contact ball bearing line is supplied by MR Industrial Accessories LLC, and our team can guide you to the right part number for your application.

Reading the code is the first step in ordering correctly. Take 5S-2LA-HSL010AD: the 5S block covers cage type and surface treatment, 2LA describes the sealing or protection arrangement, HSL marks the high-precision angular contact family, 010 sets the size, and the AD suffix defines internal clearance or preload. Each block carries its own selection information, so decoding the full designation avoids ordering errors.

These bearings show up in milling, grinding and machining center spindles, where speed and precision are critical, as well as in metrology equipment, rotary tables and transmission systems that need axial rigidity. Their high-speed capability makes them a fit for demanding automotive and aerospace work.

Selection depends on load direction, rotational speed and lubrication method. Mounting calls for accurate alignment and, in many cases, opposed pairs. The 2LA seal keeps contaminants out, but confirm it is compatible with the lubricant in use. Preload and internal clearance, set by the suffix, influence rigidity and service life, so follow the manufacturer's adjustment guidance.

Equivalents require care: every manufacturer uses its own nomenclature. A bearing from another brand may match an NTN HSL part, but dimensions and tolerances must line up exactly. Compare bore, outside diameter, width and load capacity rather than trusting the part number alone. If you send us measurements or the original number, we can help identify the correct part.

To request a quote, message us on WhatsApp or by email with the part number or model marked on the bearing. We reply promptly and can point out a compatible alternative when one applies.
