  • Radial Bearings
    to deep-groove bearings. But the same filling notch that permits an increased radial load cuts thrust capacity to about one-third that of deep-groove bearings. At higher thrust loads, balls start to contact the notch. For the same reason, tolerance to misalignment is considerably less than
  • Design Characteristics of Radial Bearings
    Single row radial ball bearings with balls separated by a cage can support radial loads, axial loads and tilting moments. A full complement V-type ball bearing can support only radial loads and some low axial loads. Maximum permissible speeds for ball bearings are mainly related to the bearing
  • 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
  • Ball Bearing Radial Play (Internal Clearance)
    At first glance, ball bearings are relatively simple mechanisms. However, an analysis of their internal geometries reveals that they are quite complex. For example, the ball to raceway conformity, the radial play, and the number of balls all impact the ability a ball bearing to support loads under
  • NASA Tech Briefs - High-Temperature, High-Load-Capacity Radial Magnetic Bearing
    A radial heteropolar magnetic bearing capable of operating at a temperature as high as 1,000 F ( 540 C) has been developed. This is a prototype of bearings for use in gas turbine engines operating at temperatures and speeds much higher than can be withstood by lubricated rolling-element bearings.
  • Bearing Load Ratings of EAD Servo and Stepping Motors
    EAD Hybrid stepping motors and brushless DC servo motors feature high quality ball bearing construction. The following table summarizes radial and axial load rating for each frame size. The ratings given assume 10,000 hours of life at 1000 RPM. They assume an ambient temperature of 25 degrees C
  • Not All Thin-Section Bearings are Created Equal (.pdf)
    Kaydon has developed a new method for calculating the Dynamic Radial Load Rating for "Thin-Section" ball bearings. The new method uses the contact stress and the number of stress cycles per revolution to calculate the capacity.
  • Avoiding Gearbox Bearing Failure Due To Lack Of Lubrication
    There are many reasons gearbox bearings fail. From torque overload to excessive radial load to shaft misalignment, there are a myriad of things to protect against. But one of the reasons that is often lost on many design engineers is lack of bearing lubrication.
