U.S. TSUBAKI POWER-LOCK ®
SL Series SHRINK DISK STYLE
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.
