Actuatorsaremechanicalcomponentsthatconvertenergyintomotion.Actuatorsplayanimportantroleinmovingandcontrollingmechanismsorsystems.Generally,wecanclassifyactuatorsintothreecategories:hydraulicactuators,scotchyokepneumaticcylindersandelectricactuators.Thisclassificationdependsonwhichenergyisconvertedintomechanicalmotion.Inhydraulicactuators,pressurizedhydraulicfluidisused.Inascotchyokepneumaticcylinder,compressedgasisused;inanelectricactuator,electricalenergyisconvertedintomotion.Combactuators,hydrauliccylinders,screwjacks,steppermotors,electricmotors,etc.arecommonexamplesofactuators.Inthisarticle,wecandistinguishbetweenhydraulicactuatorsandscotchyokepneumaticcylinders,whicharemainlyusedindifferentindustries.

I.Applicationsandcharacteristicsofhydraulicactuators:
