Bar Hole Ringstone

  • Bar Hole Ringstones are flat on both sides with a straight hole through the center of the part.
  • The straight hole ID design restricts lateral movement of an inserted shaft or pivot or can also be used in water jet nozzles to control fluid flows.
  • Typical applications include precision instrumentation devices; such as measuring instruments, dial indicators, watches, altimeters, gyros, gauges, compasses, fluid or gas flow devices, gimbals, meters, and many other bearing applications.
  • Custom dimensions and tolerances available upon request.
