ContiTech D-type air actuators with easy-to-replace components
ContiTech is adding the D-type series to its air actuator product range. This series is designed in such a way that every single component, right up to the rubber bellows, can be quickly and easily replaced. This simplifies the recycling process, as rubber and metal parts can be separated more easily. In addition, ContiTech produces the connecting plates for the D-type series with diameters of up to 175mm from aluminium. This is the standard material in many pneumatic products, and is now available in the ContiTech air actuators as well.
Dr Olaf Kluth, head of the Industrial Applications segment at ContiTech Air Spring Systems says: "The products have been perfectly designed to meet market requirements. The connecting parts have been designed in such a way that the air actuators can also be used as a replacement for bellows, as is already the case with the Dunlop, "Springride' in France, for example. Dunlop "Springride' has now ceased production. One of the results of this is that demand for ContiTech has risen."
The product range of the new D-types can be divided into eight different sizes, each of which is available as a one-, two- or three-convolution bellows and has dimensions of 80mm/type 22 up to 435mm/type 816. Without a piston rod, strokes of more than 400mm are possible. The feasible lifting force range extends from 0.5KN to 80KN.
ContiTech produces its air actuator designs using high-tech elastomer qualities, and the company says that its actuators are highly durable, have a long service life and are cost effective. The design of the dimensionally stable elements is comparable with that of a tyre or air spring. They are used to produce extreme force in pneumatics where little space is available for installation and exceptionally harsh conditions are prevalent.
Well-known applications of the D-types are power collectors in trains (pantographs) and paper machines. In addition, there are the comparable applications such as those with pneumatic cylinders based on a simple principle, for example in automation, glass, wood and agricultural engineering.
With the development of new, removable air actuators, ContiTech has re-structured the designation of the product range. The D-types will now complement the tried-and-tested air actuators with firmly attached connecting parts (C-series), air actuators with bead ring connecting parts (R-series) and rolling lobe actuators with plastic connecting parts (S-series).
