The NTN HT series angular contact ball bearing is a component designed to withstand combined radial and axial loads, with high precision and high-speed rotation capability. It is used in machine tool spindles, high-frequency motors and measuring equipment where rigidity and rotational accuracy are critical. Its inclined raceway design allows angular contact that improves load distribution and reduces friction.

The HT series designation is interpreted according to NTN nomenclature: the base number indicates dimensions and the suffix DB indicates a tandem mounting with preload, while the letter M refers to the type of machined brass cage. For example, in 70M6DB and 70M8DB, 70 corresponds to the diameter series, M to the cage, 6 or 8 to the size and DB to the pairing. Knowing these codes makes identification easier when requesting a quote.

In Argentine industry, these bearings are used in milling machine, grinding machine and machining center spindles, as well as in high-speed electric motors and metrology equipment. They are also present in the automotive sector, in test benches and in applications requiring axial and radial rigidity with minimum clearance. Their ability to run at high speeds makes them suitable for precision machining processes.

To correctly select an angular contact bearing, consider the axial and radial load, the operating speed and the type of lubrication. Mounting must ensure precise alignment and adequate preload, which is achieved with DB pairing. Sealing and lubrication are critical: in contaminated environments additional protection is recommended. The machined brass cage provides strength and heat dissipation under severe conditions.

Equivalences between brands are possible if dimensions, load capacity and type of execution are compared. An angular contact bearing from another brand with a similar designation can be interchanged, but always verifying tolerances and internal clearance. At MR Accesorios Industriales we can advise you on compatibility and quote the exact reference you need.
