Worked well for what I needed. I have an 8mm diameter Z-shaped aluminum bar that attaches to the motor shaft and raises the rubber assembly. I had to put something on the shaft where it meets the rubber to reduce friction/wear and these linear bearings worked great because they rotated on the shaft. It has a bit more drag than I expected but they are built for linear movement and work well enough for my application so I can't complain.
