I have an air handling unit down due to fan failure .... its a DC

the form
of rubber isolating mount/bush.
Presumably to provide noise isolation and some self-centering.

The bearing has seized .. OK I can replace that, but the rubber bush it
mounts in is very soft ... so assume damaged.

Yes I Did look at the photo!
If the new bearing is not a good fit in that rubber housing I would
try some
Silicone Moulding Rubber


That was my thought too. Perhaps a film of grease on the moving parts
so they are still free to turn after potting in rubber.

Lots of corrosion on what was a galvanised? support.
Where does this blower live ?.


In a domestic heat recovery ventilation unit
