Deep groove ball bearings are particularly versatile. They are suitable for high and very high speeds, accommodate radial and axial loads in both directions and require little maintenance. Because deep groove ball bearings are the most widely used bearing type, they are available from SKF in many designs, variants and sizes.NSK manufacture a full range of deep groove ball bearings. These bearings are the most common type and are used in a wide variety of applications.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.Prelubricated bearings have integral seals, or shields, which are packed with long-life grease. In many applications, these bearings can be used without supplementary seals, closures, or protective devices. This design also offers the lowest possible manufacturing costs to the end user.
