NTN HSE series angular contact ball bearings are built for combined radial and axial loading where rotational accuracy matters. The raceway and ball geometry keeps friction low while allowing high speeds, which suits machine tool spindles, measuring equipment and other systems that need rigidity and repeatability. MR Industrial Accessories LLC supplies these bearings and quotes them against the exact part number you specify.
Reading the part number is the quickest way to confirm you are ordering the right bearing. Take 5S-2LA-HSE910UC: the 5S prefix means ceramic balls, which cut weight and thermal expansion; 2LA covers cage and lubrication type; HSE marks the high-speed, high-precision series. The three digits give the size, so 5S-2LA-HSE911UC and 5S-2LA-HSE912UC step up in size from the 910. The UC suffix sets internal clearance and preload.
Typical applications include milling, grinding and machining center spindles, plus metrology equipment, drill heads and positioning systems. Shops that hold tight tolerances rely on them because they sustain high speeds without sacrificing accuracy.
Selection comes down to axial and radial load, rotational speed and the rigidity the application requires. Mounting must be aligned precisely, since any deviation shortens service life. Lubrication, grease or oil, carries heat away, while seals or shields keep contamination out. Follow the specified clearance and preload to get the intended performance.
Bearings from other makers that use the same high-precision angular contact nomenclature can serve as replacements, but interchange is never automatic. Check dimensions, load capacity and clearance before substituting. If anything is unclear, our team can help you compare options.

Frequently asked questions
- What does the 5S prefix mean in these bearings?
- It tells you the bearing runs ceramic balls rather than steel ones. That lowers weight, resists corrosion better and reduces thermal expansion, supporting higher speeds and precision in demanding work.
- How do I choose the right UC suffix?
- UC defines internal clearance and preload. Your choice depends on load, speed and the rigidity you need. Share the application and full part number with our technical team and we will help you pick the right one.
- Are they interchangeable with bearings from other brands?
- They may be interchangeable with bearings that follow the same nomenclature and specifications. Always verify dimensions, load capacity and internal clearance before replacing.
