A.P. LOCK
(Keyless Bushing)

A.P. Lock (Keyless Bushing) is a power transmission component that
enables to clamp shaft and hubs (i.e. pulley, gear etc.) simultaneously
through its surface pressure. S.I.M provides diverse options in regards
to size, body material and surface treatment.

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.)
