I'm sure you can figure something to do with them.
In the "hanging" competition, we had a lead screw turned by an FP motor/gearbox to do the lifting of the top section which had the bar-hooks, and once they were hooked, the same leadscrew had to hoist the main (90-110#) part of the robot. What held the leadscrew ?
A pillowblock mounted bearing, doing great work as a thrust bearing.
