Z7B Expansion Sleeve Shaft Locking Device Assembly, Diameter 24x50 to 50x90mm
Z7B Expansion Sleeve Shaft Locking Device Assembly, STK603/TLK603/RCK19/SD71/SCD, Bore Diameter 24x50 to 50x90mm
The Z7B Expansion Sleeve is a keyless shaft locking device designed for high-torque transmission in CNC machinery and various industrial applications. The keyless connection structure allows the inner and outer sleeves to shrink and expand under axial force, creating a tight fit between the shaft and hub. This generates enough friction to transmit torque efficiently, ensuring smooth operation.
