A simple X/Y system for loading material
into a printing system
SMI attached aluminum pillowblock slide bush
components to a custom machined metal plate.
To ensure fast, smooth operation, SMI chose a
slide bush with raceway surfaces that are precision
ground. Since the contact areas between the ball elements
and the precision ground raceway surface of the
slide bush were minimized, the slide bush provided low
friction compared to other linear motion mechanisms.
An inexpensive linear/rotational
movement solution
They needed the ability to move X as well as Theta.
This was accomplished by putting a flat washer
on a slide bush, slipping a needle bearing on the
outside of the very smooth steel housing then
putting another flat washer on the top. SMI
incorporated this particular slide bush because
there is a ring groove at the end of it.
They invented a shop floor device for
measuring materials as long as 9 feet
