In a contained space. Dimensionally are more compact than other types of rotary actuators. The range includes bore sizes from 10 to 100 in 4 configurations: - basic. - with rotary angle adjustment mechanism. - - with rotary angle adjustment mechanism and sensing support. The bodies are in aluminium , the shafts in chrome plated steel and the seals in NBR. The sensing support kit enables for the sensors to be positioned in any position. The rotary angle adjustment mechanism enables the adjustment of the complete rotation on bore sizes 10 to 40 while on the others sizes carries as standard hydraulic dampers which enable the adjustment only of the last part of the rotation. The units can be fixed using the thread on the body or the through holes on the body. On bore sizes 50 to 100 the shaft runs into ball bearings which ensure high resistence.o rotante è guidato su cuscinetti a sfere che assorbono i carichi radiali e assiali, garantendo durata e affidabilità. assiali, garantendo durata e affidabilità.
