Rohlix Linear Actuator Two Piece 3/8" Shaft Diameter 15 lb Thrust Rating 2.25" Length

The Rohlix is a threadless, mechanical screw-type linear actuator that converts rotary motion into precise linear motion and thrust with the unique ability to slip if overloaded. The Rohlix uses rolling element ball bearing that trace a helix pattern along a shaft, which produces a rolling helix, or Rohlix for short. Rohlix Actuators have six precision ball bearings, three at each end of a two-piece aluminum block. Mounted at an angle relative to the drive shaft axis, the bearings convert drive shaft rotation into proportional linear travel. This is called lead. The lead is determined by the angle of the bearings in the block. The linear thrust capability of the Rohlix is determined by the friction between the surfaces of the angled bearings and the drive shaft. Thrust capability is varied by adjusting the cap screws located on the top of the load block.
