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
  • The most standard clamping structure between shaft and hub
  • Relatively higher clamping force

  • Recommended tolerance (Shaft’s OD: h8, Hub’s ID: H8)
  • Simple structure for easier installation & handier maintenance
How to Order
Principles

※ If more than 2pcs of SAPL-D1 are mounted simultaneously, the clamping force on shaft (permissible torque) becomes higher.

  • SAPL-D1/ 1pc mounted: Tc (Max. Permissible Torque)
  • SAPL-D1/ 2pcs mounted : Tc (Max. Permissible Torque) x 1.9
  • SAPL-D1/ 3pcs mounted : Tc (Max. Permissible Torque) x 2.7
