  • 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

  • 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
  • Bearing Loads
    applications, higher loads can be accommodated. is based on two considerations: 1. Load at which the ball-raceway stress approximates that calculated for the heaviest-loaded ball under the limiting static radial load. 2. Load causing the contact area between the ball and raceway to climb over
  • 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
  • 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
  • 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
  • A few guidelines for fitting miniature bearings into assemblies
    of thermal gradients) estimate the reduction in bearing radial play by 80% of the actual diametrical interference fit. This 80% figure is conservative, but it is a useful design guideline. Depending on materials involved, this factor will range from 50 to 80%. The following is an example
  • Slimmed-Down Magnetic-Bearing Systems Fit More Rotating Machinery Applications
    , two radial magnetic bearings support and position the shaft in the lateral (radial) directions, and
  • 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
