NTN HT series angular contact bearings are ball bearings whose raceways are positioned to handle radial and axial loads acting together in one direction. This angular arrangement gives them greater axial capacity than a deep groove ball bearing. They suit setups that call for precision and rigidity, such as machine tool spindles, pumps, compressors and gearboxes.

Reading the code: the number before the HT suffix gives the size, while HT identifies the series. So 7000HTDB, 7001HTDB and 7203HTDB all belong to the HT line. When you see 7004HTDB or 7206HTDB, the DB ending points to a particular mounting arrangement, typically two bearings paired together. Understanding these elements makes it easier to order the right replacement.

In service, these bearings appear in milling and lathe spindles, centrifugal pumps, air compressors, gearboxes and transmission equipment. They are common in metalworking, food processing, petrochemical and automotive plants. Because they can take axial loads, they fit mountings where combined stresses occur and running precision matters.

Selection depends on the axial load direction, internal clearance and sealing method. HT series bearings are often fitted with an interference fit on the inner or outer ring, depending on the application. Use lubrication matched to the operating speed and temperature, and keep supports aligned to prevent parasitic loads. Careful mounting helps the bearing reach its full service life.

NTN angular contact bearings can be interchanged with other brands that use the same dimensions and suffix system. If you have a competitor's code, we can point you to a compatible equivalent. Because tolerances and clearance affect interchangeability, always check the specifications before substituting.
