GGB DTS10 Cylindrical bushes

DTS10® Metal-Polymer Hydrodynamic Composite Bearings

CHARACTERISTICS

  • The first polymer-lined precision bearing for lubricated conditions offering low friction and high wear resistance that is designed to be machined on-site for tight tolerances
  • Excellent wear resistance and low friction in lubricated hydraulic applications
  • Excellent chemical resistance, fatigue strength, cavitation and flow erosion resistance, and good behavior in dry start-up conditions
  • A minimum overlay thickness of 0.1 mm permits, under carefully controlled conditions, machining of the assembled bore for improved dimensional tolerance and reduced geometric defects, while retaining a thin layer of PTFE sliding surface
  • Compatible with most standard machining processes including turning, broaching, reaming, and milling
  • Lead-free material compliant to EVL, WEEE, and RoHS specifications
