  • Radial Bearings
    bearings are the most widely used ball bearings. In addition to radial loads, they carry substantial thrust loads at high speeds, in either direction. They require careful alignment between shaft and housing. The ball complement of a deep-groove bearing is limited to the number of balls that can
  • Bearing Loads
    In some applications, allowable load seriously influences selection. Major variables affecting load capacity are ball size and number and internal geometry of the bearing. Primary consideration is given to static ratings. A bearing may be deformed permanently by high loads on nonrotating bearings
  • What Is Bearing Preload?
    Bearing Preload is an axial or thrust load applied to a bearing that removes excess play. There are many ways to apply preload, as well as many benefits and potential problems with preload. This article will provide an overview of bearing preloading in common radial and angular contact ball bearing
  • Slimmed-Down Magnetic-Bearing Systems Fit More Rotating Machinery Applications
    rolling-element, plain, or thrust bearings, odds are that power sources, control electronics, and magnetic fields don't enter the picture. But active magnetic bearings are replacing oil-lubricated bearings in many applications. Magnetic bearings support rotating machinery without contaminating
  • Angular-Contact Bearings
    One-directional thrust bearings can support heavy thrust loads in one direction, combined with moderate radial loads. High shoulders on the inner and outer rings provide steep contact angles for high thrust capacity and axial rigidity. Bearings with contact angles from 15 to 40 are available
  • Magnetic Bearings Come Of Age
    , position sensors, and controller and control algorithms. Typical units consist of two magnetic radial bearings and one magnetic thrust bearing. They control the shaft along five axes: two axes for each radial bearing and a fifth axis along the shaft. Magnetic bearings have stationary and rotating
  • A few guidelines for fitting miniature bearings into assemblies
    The upper curve in the chart shows a single-bearing deflection curve. When two bearings are preloaded together and subjected to an external thrust load, the axial yield rate for the pair drops because of the preload, the interaction of the forces exerted by the external load, and reactions
  • Cylindrical Bearings
    Cylindrical roller bearings have high radial capacity. Their low friction permits operation at high speed, and thrust loads of some magnitude can be carried through the flange-roller end contacts. Although the rolling elements are called "cylindrical, " they are not true cylinders. True cylinders
  • When space is at a premium
    , support radial loads. Needle rollers go between the cup bore (outer raceway) and shaft OD (inner raceway). Most applications depend on a housing press-fit to both size and locate the bearing. The design can accommodate seals, additional oil holes, and hold grease, if needed. Drawncup bearings
