Complete bearing housing for the automatic wiper on Hanovia medium-pressure ultraviolet disinfection systems, catalogued under part number 180016-01. The bearing housing carries the wiper drive shaft where it enters the chamber end and keeps it running true under the drive load. Supplied complete, so the bearing, seals and retaining hardware do not have to be ordered and assembled separately — the usual choice when a housing has worn rather than lost a single component. This is the automatic (motor-driven) version; the manual-wiper housing is a separate item in this catalogue. Reference number 2266-0103.
