Product details
Push effort climbs noticeably once a castor stops rolling freely. Part 3220ER is the center castor on the SEBO DISCO floor polisher, item 30 on the machine's parts diagram, and it is the central roller that carries part of the machine's weight and lets it swing around table legs and into corners without dragging.
Castors fail in three familiar ways. Hair and thread wind into the axle until the wheel stops turning and starts skidding; the tread flat-spots where the machine has sat loaded in one place for months; or the wheel splits and runs on a broken edge. All three feel the same from the handle, which is a machine that has become heavy to steer and wants to track straight when you ask it to turn. On hard flooring a skidding castor also leaves marks, which is usually what forces the issue. Clear the wound debris from the mounting point before the new castor goes in, and check the rear castor 3254GS at the same time, since they wear at similar rates. A castor that has been skidding for a while will often have worn its mounting as well, so look at the seat it sits in rather than just the wheel itself.
