ROSTA oscillating drive heads type STI are flexible joints transmitting the acceleration forces from the eccentric drive to the oscillating machine part – free of play, silently, reliably, and without requiring maintenance. The common maintenance problems which are characteristic of these drive components are thus eliminated.
The inner square section (core) and the trough are joined together by a so-called \” 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 from aluminium.
