Product Features
  • Self-centering function (prevention of slight off-center matters)
  • Designed to suit relatively smaller hubs (as there is only small difference in dimension between inner(d) and outer(D) diameters, as well as its surface pressure is low)
  • A wide range of standard inner diameters (from Ø5 to Ø50)
  • Simple structure for easier installation & handier maintenance
  • Diverse material & finish options available (e.g. stainless steel body for vacuum area, electroless nickel plating etc.)
