 9.8 Ncwton(N) = 1kg = 2.2LBS

 
 *The max force tolerance is ±30% for the HD18 series Oil Damper-SOS 
 
  1) Hydrauilc stroke
  2) Mechanical stroke
  3) Test speed 100 mm/s
  4) Piston rod down, piston flow only in oil = hydraulic stroke, A
  5) Piston rod up, maximum possible stroke in oil and air chamer = mechanical stroke,A*

  F_Z : Blocking force in traction direction (N)
  F_D : Blocking force in compression direction (N)
