Deep groove, or single row radial, ball bearings are the most widely used bearings. They utilize an uninterrupted raceway that makes them optimal for radial loads .This design permits precision tolerance, even at high-speed operation. NTN ball bearings use standard cages of pressed steel, as well as machined, brass cages for high-speed applications. NTN also offers bearings with locating snap rings.
