Sounds like pretty severe duty to me. - if I understand what you're saying; 6000 rpm is 100 times per second. And you want this thing to change direction TWICE per revolution, right? So that means 200 "reverses" per second? So that would be moving at the rate of - say - valves in a 12,000 rpm engine? - or the injectors operating? But with much higher loads, right? What else? I don't know...
