    Question (lead screw bearing support)

    i am building a 4x4 steel table cnc. i will be using a 3/4 4 start acme screw for both the x and y axis. I will also be using lovejoy couplers at the steppers. The question is can i use a Fastenal 3/4 pillow bearing block w/ a 3/4 collar on each side of the block for my leadscrew supports. thanks in advance for your input
