So I understand these things:
There are sliding bearings in similar colors as copper, brass, bronze: These bearings have pored surfaces and store in the pores lubricant, it gives them temporary emergency running properties when the general lubrication is already gone.
These bearings can e.g. be rotated and pushed at the same time on a rotating shaft without taking damage or even damage to the shaft.
Please Use the google image search and you'll find thousands of examples.

I think "UMO" and "UMO +", both use identical plain bearings.
