•Compatibility : The mounting face and major parts are mutually compatible with YAH type cylinder. •Small Size & Light Weight : Is it 30% shorter than YAH type cylinder so that it is small in size, light in weight and high speed rotation. •Safety Guaranteed : It contatins check valves so that pulling force is kept for a certain time upon power failure, securing safety. •Leakage Prevention Design(Patent Registration:0172805) : Cylinder body is designed with a leakage prevention structure to totally eliminate the possiblility of leaking. •Highest Draw Pull : As weight is reduced and draw pull is increased, it gurantees the best machining efficiency and stronger power.
