CSF-A2 type locking assembly couplings

 1.Type A2 expansion sleeve consists of an open biconical inner ring ,an open biconical outer ring and two biconical compression rings.

 2.Tighten with an inner hexagon bolt,and the elastic ring does not move axial relative to the hub when tightening.

 3.Compared with type A1 ,the same compression force can produce greater radial pressure and transmit greater radial pressure and transmit greater load.

 4.For the convenience of disassembly ,there are disassembly screw holes on a pressing ring,and there are 2~4 places along the aircumference.

 5.Widely used in packaging ,printing,textile,machine tools and other machinery.
