Motion Constrained is proud to start supplying Ball Screw Linear Actuators. These are custom built to our specifications. Each Actuator comes with t-nuts for mounting, as well as a .25″ motor coupler. These are roller guided with radial bearings for support, a rolled ball screw and internally circulating nut. The body is made from extruded aluminum with machined aluminum end blocks and ball bearings. The mounting plate for the motor will accept either a Nema 17/ 42mm or a Nema 23 / 57mm frame. We offer these actuators in 100mm, 300mm, and 600mm length of travel.
