Z19B Expansion Sleeve Shaft Locking Device Assembly Bore Diameter 14-60mm STK251/TLK251/RCK55/KTR125.1 Fastening Tension Sleeve
Z19B expansion sleeve is a transmission part product with keyless connection structure. Under the action of axial force, the inner and outer sleeves of the expansion sleeve shrink and expand to make the shaft and hub closely fit and generate enough friction to transmit torque, so as to achieve the purpose of mechanism operation.
