Align Bearings 4x8x3mm (4)
Fit nicely, seem well greased up and run smooth with only little play when new. They don't take kindly to crashes though; gets damaged easily and feel rough and raw when turned afterwards. So normal modus operandi for me is to change them pretty much after every crash (i.e. when they don't feel smooth).
