DYSON DC04 DC07 DC14 Brush Bar Agitator Bearings - 2 x / Pair - Non-Clutch models. THESE BEARINGS ARE APPROXIMATELY 22mm DIAMETER - The bearings for the non- clutch control model are approximately 22mm diameter (whereas the bearings for the clutch model are approximately 16mm diameter), so please check this PRIOR to making your purchase! Why not take the opportunity to also fit a new drive belt whilst removing the old belt to fit  the new bearings?- Please see my Belt & Bearings kit item - Please enter into your ebay browser bar the following item number: 257456625948. If you are still unsure whether your Dyson has clutch brush bar control or not, please send me a photo of your Dyson taken from the same angle as one of the photos in this listing. NOTE: Rubber sealed bearings such as these, offer much better protection against contaminants (e.g moisture & dust) in comparison to metal sealed bearings (the latter of which are better suited to high speed and higher temperature applications e.g. for motors).
