Depending on the roller base design, i have used with success a very 
large diameter O-ring of 3 to 4 mm cross section on the drum.  The drum 
will generally drift into the same direction.  Place the O-ring such 
that the drum will stay approximately in the center once the ring ****ges 
against one of the rollers.  Test it with a normal water load to see if 
the whole thing remains stable for the duration of the longest process
step.
