For equipment that handles combined radial and axial forces in one direction, the NTN angular contact ball bearing is a common choice. Its offset raceways create an oblique ball-to-raceway contact, which gives it more axial capacity than a deep groove ball bearing. Typical uses include machine tool spindles, pumps, compressors and gearboxes, where precision and rigidity matter.

Reading the NTN designation helps you identify the right part quickly. In 5S-7000U, the 5S prefix points to a special execution with a synthetic cage and high precision, 7000 is the diameter series, and the U suffix means an angular contact design with a 25° contact angle. The same pattern applies to 5S-7001U and 5S-7002U, where the size changes with the bore diameter. Recognizing these codes makes replacement easier.

These bearings appear in machine tools, automation equipment, centrifugal pumps, screw compressors, speed reducers and grinding spindles. They suit tandem or paired mounting depending on load direction, since they can take axial forces. Industries such as metalworking, food processing and petrochemicals rely on them where combined loads and high speeds are present.

Selection depends on the axial load direction and size, rotation speed and lubrication. Mounting calls for a precise fit and often a controlled preload to reach the wanted rigidity. Shaft-to-housing alignment is critical, because small misalignments add load and shorten service life. Choose sealing or protection for the environment, whether dust, humidity or contaminants, and pick grease or oil based on heat dissipation needs.

NTN angular contact bearings can be interchanged with other brands using the same international series and suffix nomenclature. Still, verify tolerances, contact angle and preload, as these can differ between makers. If you have a code from another brand, send it and we will review it and point you to a compatible alternative. We can also quote the exact size you need.
