ROSTA oscilllating drive heads type STI are flexible joints transmitting the acceleration forces from eccentric drive to the oscillating machine part - free of play, silently, reliably and without requiring maintenance. The common maintenance problems which are a common characteristic of these drive components are thus eliminated.
The inner square section (core) and the trough are joined together by a so-callled "fork". The outer housing is screwed to the slider crank rod and locked. Right or left-hand threads are available, which allows the crank length to be adjusted easily. The drive heads are made out of aluminium.
