• 1) Not possible for piston Ø 25 mm0.98 in
• 2) Not possible for piston Ø 200 mm7.87 in
• 3) Position of trunnion freely selectable. When ordering, always specify the dimension “XV” in the plain text in mminch. With piston Ø 25 mm0.98 in, the trunnions are at the cylinder head.
• 4) Observe the admissible stroke length, see “Admissible stroke lengths” in the project planning information.
• 5) See dimensions. Not possible with type of mounting “K”.
• 6) Not possible with piston rod end “E”.
• 7) Not possible with piston rod Ø 12 mm0.47 in.
• 8) All graphical representations in the data sheet show position 1.
• 9) Always specify the attachment of inductive proximity switches or piston rod extensions “LY” in the order in the plain text.
• 10) Not possible with type of mounting “M”.

Order example:
CD70B50/22-200Z1X/01HBDM1-1A
With special versions, an “X” will be inserted in the type key at the corresponding position and an SO number will be amended at the end.
