  • Hollow Roller Bearings
    and reduces radial vibration and radial runout. The proper lubrication of hollow roller bearings is critical for their proper operation and bearing life. Hollow roller bearings are used on turbine shafts, as well as in grinding, milling, and workhead spindles where precision and stiffness are required.
  • Double-Row Tapered Roller Bearings
    Two-row or double-row tapered roller bearings have increased radial load capacity compared to single-row bearings. They can also handle thrust loads from both directions. The rollers can be configured in a converging or a diverging orientation. In converging double-row tapered roller bearings
  • Spherical-roller bearings graduate to a new class
    Advances in materials, design, and processing have combined to triple bearing life. EDITED BY KENNETH J. KORANE Explorer bearings are available in both sealed and unsealed versions, and are dimensionally interchangeable with existing spherical-roller bearings. They have higher load ratings and up
  • Factors to Consider When Choosing a Crossed Roller Bearing (.pdf)
    , another type. of bearing has established its place in the pantheon of friction reducing devices ­ the crossed roller bearing. What high-tech microscopes, as well as advances in wafer manufacturing, robotics and vision inspection have. in common, is their growing reliance on crossed roller bearings
  • Bearing Closures - Bearing Seals and Bearing Shields
    Ball and roller bearings are available with different types of shields and seals. These are commonly referred to as closures. Closures can extend bearing life by preventing contaminants from reaching the critical surfaces inside the bearing, and they help retain the lubricant in the bearing

  • Cylindrical Bearings
    in high-speed, lightly loaded, cylindrical roller bearings is roller skidding, which can lead to premature bearing failure. One technique to combat skidding is an out-of-round raceway, which pinches the rollers at two diametrically opposite points. Another technique is the use of two preloaded hollow
