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
  • Excellent for high rotating application (AL-Alloy Material has lower moment of inertia)
  • Designed to suit not only AL-Alloy pulleys but also steel ones with higher surface pressure comparing to SAPC series
  • Designed to suit clean rooms with high corrosion resistance
  • Exactly identical dimensions with SAPL-A Series
  • Self-centering function (prevention of slight off-center matters)
