SEBO Left-Hand Bearing Block Cover for the 370 COMFORT

Left-hand bearing blocks sit behind a cap, and part 20123ER is that cap for the SEBO 370 COMFORT. It closes over the block supporting the left end of the brush roll, keeping the bearing seated in its housing and shielded from whatever the roller picks up off the floor.

Hair and fine grit are what finish off brush roll bearings, and this cover is the first line of defence against both. Once it cracks or goes missing, debris reaches the bearing directly and the block itself can start working loose in its housing. Noise and a wobbling roller follow soon after, and by that stage the bearing has usually been damaged as well. A new cover restores both the shield and the location, which is why it is worth fitting before the noise starts rather than after.

Left-hand is the important word here, since the two ends of the roller are not interchangeable and the right-hand side carries its own part number. This cover is listed for the 370 COMFORT. It is better treated as a service item than a repair item, because a sound cover is what keeps a good bearing good. Anyone searching for a SEBO 370 bearing block cover, a brush roll bearing cap or a 370 COMFORT roller end cover is looking at this component.
