Expansion sleeve operation principle, application and connection

     Expansion sleeve (also called swelling link sets, free bond bearing)is a keyless connection device, its principle and use the high strength tensile bolt action, great holding force between inner ring and outer ring, the shaft and the hub, so as to realize the keyless connection parts and shaft. When subjected to load, compositeload transfer by combining pressure expanding sleeve and shaftparts, and accompanied by the friction torque, axial force or two persons.

Tensioning Roller&Sprocket

     Expansion sleeve connection mainly has the following advantages:the high precision; installation / adjust / convenient disassembly;high strength, stable and reliable connection; can protect the equipment from damage under overload, especially suitable forheavy load transfer. Widely used in heavy machinery, light industrial machinery, food machinery, packaging machinery, textile machinery, printing machinery, CNC machine tools, automation equipment etc.、
