LEAD SCREW LINEAR ACTUATOR Helix Profile Rail Linear Actuators feature smooth, clean and quiet linear positioning. The PRA is built with a 3 series stainless steel precision lead screw coated with the Helix H4X PTFE dry lubricant that extends the lead screw nut life by 8-1X. The lead screw assembly also incorporates a standard or anti-backlash nut to eliminate axial and radial lash. The PRA linear actuator utilizes a precision ground profile rail for guidance to deliver pitch, roll and yaw guidance. These pre-assembled linear actuators offer a turn-key solution for linear motion solutions and quick deliveries.
