Hi Men,Good morning!. I used “Simply Bearings” a few weeks ago to buy two tiny (12mm x6mm bore)for my noisy flew fan on my C/h wall boiler.They arrived the next day for less than £5 including p&p! The quote from Boiler Man £200,”as you will need a new fan motor,and they only come complete with casing,fan etc plus VAT, blaa blaa!! I fitted the new bearings and serviced the boiler in less than two hours,Tidy!!
