Double acting pneumatic cylinders
rodless, series S1, S5 and VL1 |
|
These mechanically coupled rodless cylinders offer long strokes with reduced instalation place. Thanks to max. stroke up to 6 meters, these cylinders can be used in such an aplpications, where use of standard cylinder is impossible. This series uses well-proved two bands principle. Series S5 is equipped with slide guide with plastic bearings, series VL1 is equipped with rolling guide with ball bearings. There is also locking unit available for series S5 and VL1 (for details please contact our technical dept.) |

Admissible load
Examination and selection of cushioning
In a system with dynamic masses as for example with the rodless cylinder, it is essential to control the dissipation of the kinetic energy during braking until standstill. The first thing to be done is to select cushioning. Two kinds are available: 1. internal cushioning and 2. external cushioning. It is of special significance that the carriage with load does not hit the end cap at high speed. | |
If the point corresponding to a given load and speed lies beneath the appropriate curve, the cushioning is able to absorb the kinetic energy of the system. Vice versa if the point lies above the curve, the cushioning is not able to absorb the kinetic energy, in which case you must: a) reduce load and keep the speed the same b) decrease the speed and maintain the load c) select a larger cylinder d) use external damping Cushioning capacity is shown in the diagrams on the right (in respect to final speed, when carriages get close to end caps). |

Adjusting of the carriage of series VL1
In case of off-centred loads it is necessary to adjust the screws A as shown below. The arrows indicate the screws to be adjusted, in accordance with the position of the load. Adjust the screw A by one turn or more depending on the load. Put a drop of Loctite 242 on the screw B and tighten it thoroughly. Finally loosen both screws by 90°.
