  • New spin on spindle bearings
    in some cases. Another option is angular-contact ball bearings with integral seals or shields such as those from SKF Machine Tool Precision Technology, Bethlehem, Pa. ( ). These shields consist of molded rubber formed onto a steel backing that acts as an added barrier against contaminants. Sealed
  • Basics of Design Engineering: Bearings
    Air bearings for linear applications, segmented bearings that can be installed into hard-to-reach places, and thermoplastic bearings molded with integral pulleys or gear teeth are just a few of the recent developments from bearing manufacturers. Edited by Paul Dvorak, , Kathleen Franzinger Star
  • How to choose a linear rail and carriage for linear motion: Linear bearings give new meaning to riding the rails
    for the derating factors commonly assigned to. and ways, which are integral areas of the machine bed in. profi le rails. many machines. Notwithstanding, some traditional carriages. of magnitude higher accuracy than the round rail, a property. that is especially useful for milling and grinding
  • Screw Gear or Crossed Helical Gear Meshes - Technical Article
    . a = ­­­ (­­­­­ + ­­­­­). (7-2). modified into integers, if the helix angle were chosen properly. 2 cos1 cos2. In the axial system, the linear displacement of the helical rack, l, for one. turn of the helical gear equals the integral multiple of radial pitch. Again, it is possible to adjust the center
  • Getting the right angle
    coupling. The electronics are a factor as well, including signal processing. Angle encoders come in several mechanical options with varying degrees of accuracy. There are three basic categories depending on whether or not the encoder has an integral bearing. Angle encoders with integral bearings
  • Setting the stage for clearer images
    compliance. Integral design also helps reduce the high preload levels common in some high-accuracy leadscrews, and the associated stick-slip action. Stick-slip happens when a control system commands a motor to move a small amount but friction prevents
  • Springs
    . They retain or locate parts in bearings and on shafts. Garter springs are used primarily in oil seals. Beam springs are produced in a variety of shapes and can push or pull. Frequently, beam springs are required for additional functions and sometimes are integral to a larger part. done by helical-torsion
  • A Precise Solution to Motion Control Challenges
    lubrication wil reduce contamination. Many precision type bearings offer a wel. thought-out seal design. The Super Smart has a double-lipped wiper that's integral to the. bearing. It retains lubrication with one lip while the other lip acts as a scraper to eliminate. contaminants. Thomson also uses
