The NTN UC series angular contact ball bearing is a precision component designed to withstand combined radial and axial loads in a single direction. Its angular contact raceway design allows smooth and precise operation in applications requiring high rigidity and accuracy. It is ideal for machine tool spindles, pumps, compressors and transmission equipment operating at high speeds and requiring careful mounting.

The UC series designation is interpreted from the number preceding it: the first two digits indicate the bore diameter according to an established code, and the next two correspond to the outer diameter. For example, the 7000UC has a 10 mm bore, the 7001UC a 12 mm bore, the 7002UC a 15 mm bore, and so on up to the 7007UC with 35 mm. The UC suffix identifies NTN's angular contact series, with a specific configuration of raceways and balls that gives it its load and speed characteristics.

In Argentine industry, these bearings are used in machine tool spindles, milling machine heads, centrifugal pumps, screw compressors, high-speed electric motors and power transmission equipment. They are common in metallurgical, food and textile plants and in the automotive sector, where precision and reliability under combined loads are required. Their ability to withstand axial loads in one direction makes them suitable for paired arrangements or in combination with other bearings.

To correctly select an angular contact bearing, take into account the magnitude and direction of the loads, the rotation speed, the lubrication and the type of sealing. Mounting must ensure precise alignment and adequate axial clearance, since these bearings are not self-aligning. Lubrication can be with grease or oil, depending on the application, and it is essential to maintain cleanliness during installation to avoid contaminants that reduce service life.

NTN UC series bearings are interchangeable with those of other brands that follow the same international angular contact designation. When looking for a replacement, check the main dimensions (bore, outer and width diameters) and the load capacities, which may vary between manufacturers. If you have another brand's code, we can quote you the exact equivalent or the compatible alternative that best suits your equipment.
