Schrumpfscheibe (Spannsatz)

The Shrink Disc (Locking Assembly) is a kind of keyless coupling. Under the action of axial force of screws via an inclined plane, innerring keep close to axis/hub and generate friction force to create no backlash connection, thus transmit torque then attain the goal of running machines steadily and safely. FT-G series: High torque; External type; Easy installation; No axial movement during clamping; Tolerances: shaft h8; hub bore H8; Surface roughness: Ra max.12.5.
