The NTN HSE series angular contact ball bearing is a precision component designed to withstand combined radial and axial loads in applications where rotational accuracy is critical. Its raceway and ball design allows high speeds with low friction, ideal for machine tool spindles, measuring equipment and positioning systems. At MR Accesorios Industriales we advise you to choose the right configuration for your application.

The HSE series designation is interpreted in blocks: the prefix 5S indicates the ball material, hybrid ceramic; 2LA refers to the type of cage and lubrication; HSE identifies the high-precision angular contact series; the three- or four-digit number indicates the bore diameter; and the suffix UAD defines the axial clearance and preload. For example, 5S-2LA-HSEW910UAD corresponds to a bearing with ceramic balls, polyamide cage, HSE series and a bore diameter of 10 mm. Learn more about this coding to select the exact component.

These bearings are used in spindles of milling machines, grinding machines and machining centers, where rigidity and rotational precision are essential. They are also present in metrology equipment, rotary tables, robot actuators and high-speed transmission systems. In Argentine industry, we find them in precision machining workshops, auto parts factories and medical equipment plants, among other applications that demand reliability and repeatability.

To select the right bearing, take into account the axial and radial load, the operating speed and the type of mounting. The HSE series accepts paired configurations, with preload adjustable through the UAD suffix. Sealing and lubrication must be chosen according to the environment: polyamide cages for high speeds, and specific lubricants for elevated temperatures. Precise alignment between supports is essential to avoid parasitic loads and ensure service life.

NTN angular contact bearings are interchangeable with those of other leading brands, as long as dimensions and axial clearance are respected. When looking for equivalents, verify the bore, outer diameter and width, as well as the contact angle and load capacity. The NTN HSE series offers a reliable alternative for replacements in original equipment. If you need assistance identifying the replacement, our technical team can help you.
