APM and APMSE air expanding mechanical shafts

Main features

• It combines the air expanding system with the mechanical one.
  
• Same model of splines used for the machanical shaft.
  
• Standard core diameters: 70-76-152
  
• Same core centring of the mechanical shaft. The advantage is given by the air expanding control, i.e. a quiker expansion control.
  
• Model APM: splines expansion caused by the entrance of air, which thrusts a piston. Relieving the air pressure the springs allow the piston reversal and the splines contraction.
  A vent in the cylinder makes the piston reversal easy.
  
• Model APMSE: inflating the air pressure the springs are compressed to obtain the splines contraction.
