These are probably viscous dampers. Are they a sealed chamber?

I doubt you will find much difference in acceleration with or without them.
In general, the rotational inertia of these dampers is much less than
the motor's
own inertia, much less the machine to be moved. They may be redundant
with an
advanced microstepping drive, however. But, if you have any problems with
rattling or lost steps, put them back in.
