Thomson ball screw unit w/stepper motor BSA08FL30 30"
I took this unit off of a loader asm. The unit is in great shape. The part number is BSA08FL30 This is not a "super precision" unit with preload or anything like that.. the unit consists of the end bell bearing units, there is a superior electric stepper motor w/ motor coupler, and the ball nut. The actual distance between the bearing block (inside) is 27" so with the ball nut you get about 25" of usable travel. The ball screw is .480od, and the nut moves .2" per 360deg rev of the screw
