  • NHBB Introduces Anti-Bacterial High-Speed Bearings
    New Hampshire Ball Bearings, Inc. (NHBB) Precision Division in Chatsworth, California recently introduced the industry's first ultra-high speed bearing with anti-bacterial properties. New Hampshire Ball Bearings, Inc. (NHBB) Precision Division in Chatsworth, California recently introduced
  • Advanced bearings for high-speed machining
    for segregating "high" from "standard" speeds, but a dN value >1 million is often considered to be in the high-speed realm. A well-established means of defining bearing speed, dN = (bearing bore diameter in millimeters) X (shaft rpm). Bore diameter normalizes the speed rating because larger bearings often

The type of sleeve bearings installed as alternatives to ball bearings in fans are so-called sintered bearings (Fig. 3). They are manufactured from metal powder

  • Optimization of a Leading Edge Groove Tilting Pad Journal Bearing for Application in a Small, High Speed Multi-Stage Steam Turbine (.pdf)
    histories are presented demonstrating their effect on rotor-. bearing stability and unbalance response. The modified bearings yielded greater system stability at high speeds, reduced overall vibration amplitudes, and significantly. improved effective shaft damping on passing through the rotor's
  • Low Cost Automation Tutorial: Bearing Mounting/Retaining Method
    retention is mainly based on a concern on fit tolerance selection (see Tutorial #103). The remaining "axial direction" retention cannot be solved by press fitting of the bearing. The axial retention methods will be explained here with examples. For instance, high speed bearings such as end bearings
