  • Getting On Track with guide wheels
    acceleration. Note that the location of the eccentric wheels depends on whether the track guide way locates on the inside or outside of the wheel carriage. Abrasives used in water jet cutters quickly compromised recirculating ball-bearing guides supporting a 200-lb cutting head. The use of DualVee guide
  • Slimmed-Down Magnetic-Bearing Systems Fit More Rotating Machinery Applications
    into machinery -- their applications have been limited to date. Recent advances in magnetic-bearing technology, including miniaturization, simplification, and new integration techniques, have overcome many of these limitations. As a result, magnetic bearings are becoming more common in new machines
  • Precise moves depend on ball-screw threads
    can significantly influence its precision and material properties, especially fatigue resistance. Lead deviation, bearing journal run-out (or concentricity with the ball tracks), thread roundness, lead wobble, profile tolerances, and surface roughness all are affected by the manufacturing method
  • Tribometer Lifetime Study of Wheel Bearings
    In automotive applications, bearings form an integral part of many subassemblies, e.g., axle, engine, gearbox, etc. and their accurate characteristion needs to take into account the final configuration of the bearing system. In the case of ball and tapered roller bearings, different types
  • Guide-Wheel System: Properties, Selection & Sizing (.pdf)
    dust mixes with the bearing lubricant and damages bearing raceways and balls.
  • Glossary of Caster Terminology
    lubrication of the bearing without removing the wheel from the forks. These are known as Zerk Axles. Matching nuts are always sold with the axles. A set of rollers or balls that are encased in a track or Raceway that fit inside a wheel or in the Swivel section of a caster. For wet applications
  • Throwing it in reverse with rolling-ring bearings
    race. As the shaft turns, the inner rotating core absorbs friction as the bearings turn on balls in the raceway. When mounted on a shaft, rolling-ring bearings touch the shaft only at the apex of the central ridge on a bearing's inner race. There is clearance between the shaft and bearing on either
  • 500'000 rpm rotational speeds thanks to magnetic bearings
    Applications with high rotational speeds require outstanding bearing solutions. Air and magnetic bearings are increasingly used in place of ball bearings. When operated in vacuum, magnetic bearings offer the most advantages. A new concept for rotational speeds above 500,000 rpm will provide
