Cylinders

 
 
 
 
Hydraulic Cylinders
Hydraulic cylinders are mechanic actuators and transform potential energy fluid or hydraulic oil compressing in kinetic energy. Introducing compressed fluid allows a linear displacement.
 
 
 
Pneumatic Cylinders
Pneumatic cylinders are mechanic actuators and transform potential energy from the air compressing the kinetic energy. Introducing compressed air allows a linear displacement.
