Deep Groove Ball Bearings | NTN Beari

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

□Preload on bearing. A greater preload on a given bearing results in greater rigidity (Fig. 2.8). However, too great of a preload on a bearing can lead to overheating, seizure, and/or premature wear of the bearing. It is possible to use bearings in three- or four-row configurations in order to achieve increased axial rigidity (Fig.
