AUMA actuators with Elektro Zylinders
AUMA actuators may now be supplied with Elektro Zylinders to replace hydraulic oil cylinders, with a conventional AUMA SAC or variable speed actuator coupled to a replacement of a hydraulic cylinder.
The construction of such cylinders is via the double tube technique, whereby the flow grease lubricant is contained in an inverted bucket arrangement. Drive mechanisms are such that coarse trapezoidal threads or roller ball techniques may be incorporated, depending on whether self-locking is required or otherwise.
The move to such devices is promoted by the awareness that older hydraulic oil facilities have the potential to leak hydraulic transmission oil into city and district water supplies. The risk of such an event is now considered unacceptable, quite apart from the costs associated with clean-up.
Barron GJM has supplied 40 such arrangements to date, some for local water authorities but others for facilities in India and Malaysia. The benefits include: no more leakage of lubricant; a neat, self-contained arrangement; and high precision, with a typical 4 mm positioning capability in 4 m stroke.
