Rototilt is the original
A true tiltrotator is filled with oil It's that simple. This is why Rototilt’s tiltrotators are oil filled. And have always been.
Oil has special properties that are particularly beneficial for tiltrotators. Cog contact in a worm gear is characterised by significant friction, which produces heat. This heat is dissipated by the oil to the entire rotor housing, which is something that does not occur with grease.
One of the secrets of our technological development is Rototilt's unique test lab that we use to evaluate technical solutions. Thanks to this lab, we are well advanced in tribology, or the study of interaction of surfaces in relative motion.
