The NTN 5S-HTA0UDB series angular contact ball bearing is a precision component designed to support combined radial and axial loads in applications where rotational accuracy is critical. Its design with two opposed rows (DB) allows rigid and stable mounting, ideal for spindles and shafts that require high speed and repeatability. MR Accesorios Industriales brings you this line so you can select the exact part number your equipment needs.
The designation of these bearings is read in blocks. The prefix 5S indicates the ball material, silicon nitride ceramic, which reduces weight and friction. HTA identifies the high-precision series for spindles. The four-digit number, as in 5S-HTA010UDB, indicates the size. The suffix UDB defines the universal duplex back-to-back mounting, with light preload. Knowing this structure allows you to order the correct part number without ambiguity.
In Argentine industry, these bearings are used in machine tool spindles, machining centers, grinding machines and measuring equipment. They also appear in high-speed applications such as spindle motors for milling and drilling, where rigidity and axial precision are decisive. Their ability to work with combined loads makes them suitable for assemblies that demand strict control of clearance and concentricity.
To select the right bearing, take into account the preload, axial clearance and type of sealing. The 5S-HTA0UDB series is supplied without seals, so it requires external lubrication and a clean environment. Mounting must be carried out with suitable tools, respecting the tightening torque and shaft alignment. Lubrication with high-speed grease or oil prolongs service life and maintains precision.
NTN angular contact bearings are interchangeable with those of other brands that follow the same dimensional and precision nomenclature. If you have another brand's part number, we can help you find the exact equivalent. The 5S-HTA0UDB series stands out for its high-precision construction, and its replacement must consider the same tolerances and mounting characteristics.

Frequently Asked Questions
- What does the acronym UDB mean in these bearings?
- UDB indicates a universal duplex back-to-back mounting, with a light preload. This allows two opposed bearings to be installed without additional adjustments, achieving high axial and radial rigidity for spindles and precision shafts.
- Can they be mounted in any position?
- Yes, the universal design allows duplex mounting, either back-to-back or face-to-face, depending on the required configuration. It is important to respect the alignment and preload indicated for each application.
- Do they need special lubrication?
- Since they have no seals, they require external lubrication. High-speed grease or oil is recommended, applied according to the working conditions. Cleanliness of the environment and the type of lubricant directly influence the bearing's service life.
