  • Condition monitoring and fault diagnosis methods

    The structure of low-speed and heavy-load slewing bearings are more complex than rolling element bearings. As shown in Fig. 1, the large slewing bearing, taking the three-row slewing bearing for example, consists of an outer ring, inner ring, rolling elements, isolation blocks, connecting bolts, and other components [25].

  • Types of Bearings - How Bearings Work |

    In a ball bearing, the load is transmitted from the outer race to the ball, and from the ball to the inner race. Since the ball is a sphere, it only contacts the inner and outer race at a very small point, which helps it spin very smoothly.But it also means that there is not very much contact area holding that load, so if the bearing is …

  • Bearing load scenarios; angular contact, radial

    Radial loads act at right angles to the shaft (bearing's axis of rotation). Axial (thrust) acts parallel to the axis of rotation. When these loads are offset from either the bearing axis (distance St) or radial plane (distance Sr), a resulting moment load (M) will be created. Type A – angular contact. The type A bearing is a conventional …
