Buckling of rams
(see Figure K 12) S K = safety factor (safety in terms of buckling) In addition to the basic scenario (scenario 1), another three buckling scenarios are possible in this context (Figure K 12). Mounting [...] weight is added to the compressive stress in such cases (Figure K 13) . Figure K 12: Buckling scenarios involving vertical cylinders Figure K 13: Buckling involving horizontal cylinders [...] outwards if the compressive force F exceeds a permissible value (Figure K 12) . This value is referred to as the buckling force F K. Cylinders with a large stroke and/or a thin piston road should undergo

Figure K 20: Control of a rodless cylinder Figure K 21: Types of rodless cylinders [...] piston sides are the same size, making it easy to insert the pistons inside a pneumatic spring (Figure K 20) . In this form, the pneumatic cylinder has found favour in a range of new applications. The oldest [...] the sealing band cylinder whereby a slotted cylinder tube is sealed using steel sealing bands (Figure K 21 c) . The cylinder with actuating band or cable (a and b) is based on closed cylinders, which gives
