  • 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
  • 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.
  • Type & Characteristics of Cages, Shields and Seals
    but maximum possible number of balls. Due to the fact that the inner and outer ring have a filling slot, the axial load carrying capacity of this bearing type is low. This type of bearing is suitable for high radial load, low speed applications.
  • Hydraulic Slewing Rings and Slewing Drives (.pdf)
    torque. When the drive is rotating reversely, and parts are not damaged, the maximum torque archived is called Holding Torque. * Axial Load: Load parallel to the axis of slewing ring. * Radial Load: Load vertical to the axis of slewing ring. * Self Locking: When loaded, the slewing drive can't reverse
  • Rotary Seal Lip Design and Geometry
    Apart from the elastomeric lip material and interface between the sealing lip and application shaft, a critical design feature of the seal lip is its geometry. Lip geometry is one of several factors that directly affect the radial load exerted on the shaft. The others include the presence
  • Military Helicopter Bearings
    of standard bearings and Dicronite dry lubricated standard bearings was compared under sudden lubrication loss conditions. * Bearings: M-50 steel roller bearings. * Load: 114Kgf (250lbf) radial load. * Speed: 10,000 rpm, inner race. * Lubricant: MIL-PRF-7808 lubricant at 65°C (175°F)
