Lead Screw Linear Actuators with Triangle Nuts and NEMA Motors

Triangle nut lead screw linear actuator assemblies are motor-driven devices that convert rotary motion into linear movement using a threaded lead screw and triangular nut, factory-integrated with NEMA 08, 11, 14, 17, and 23 motors. The triangular nut geometry improves stability and load distribution for enhanced performance. Assemblies offer 3 to 11 standard lead screw and nut combinations and are available with screw lengths in inch and metric sizes. Standard and anti-backlash nut options are offered, with optional left- and right-end machining. Permanently fixed screws and motors provide accurate factory alignment and compact assembly. These actuators deliver up to 30% more torque and utilize larger thrust and radial bearings within the motor housing for increased thrust capacity and extended service life. Hollow-shaft concentricity minimizes screw runout, and preloaded bearings eliminate axial play.
