• External Lock
  Excellent for hollow shaft or space restricted installation.
• Easy to Install and Remove
  Installs or removes just by the tightening or loosening of bolts. No need to hassle with adjusting keyways and thermal fittings.
• Simple Construction
  Simply constructed with only an inner ring and taper rings A and B. Simply tighten the locking bolts to achieve a completely secure connection.

When an SL POWER-LOCK is tightened, the wedging action between the inner ring and the taper rings applies radial pressure P' on the hub exterior. This pressure P' molds the hub towards the radial direction and strengthens the hub-shaft connection. The greater the value of P', the tighter the connection.
