For machine tool spindles and other high-speed shafts, the NTN 5S-HTA0UDB series delivers the rigidity and rotational accuracy that precision work demands. These angular contact ball bearings handle combined radial and axial loads, and their universal duplex back-to-back (DB) arrangement simplifies mounting without extra adjustment. MR supplies this line to maintenance and purchasing teams across the US and Latin America.

Reading the part number helps you order the right bearing. The 5S prefix denotes silicon nitride ceramic balls, which are lighter and generate less friction. HTA marks the high-precision spindle series. The four-digit segment, such as in 5S-HTA010UDB, gives the size. The UDB suffix specifies universal duplex back-to-back mounting with light preload. With this structure, you can specify the exact variant your equipment uses.

These bearings are common in machining centers, grinding machines, measuring equipment, and high-speed spindle motors for milling and drilling. Their ability to carry combined loads suits assemblies where clearance and concentricity are tightly controlled. The opposed rows provide a rigid, stable mounting for shafts that must maintain repeatability at speed.

Selection depends on preload, axial clearance, and sealing. The 5S-HTA0UDB series comes without seals, so external lubrication and a clean environment are required. Use appropriate mounting tools, follow the specified tightening torque, and verify shaft alignment. High-speed grease or oil helps preserve precision and extend service life.

NTN angular contact bearings interchange with other brands that share the same dimensional and precision nomenclature. If you have a competitor's part number, we can help identify a matching equivalent. When replacing a 5S-HTA0UDB bearing, confirm that tolerances and mounting characteristics align with the original specification.
