sourcing map 636ZZ Deep Groove Ball Bearings Z2 6mm X 22mm X 7mm Double Shielded Carbon Steel 5pcs

Brought to repair some trolley wheels, so far so good

EDIT: Had to update my review literally a few hours after my original review below as the 3 bearings I believed to be ok have already failed due to their poor quality. These are being returned for a refund as they are utter rubbish and actually caused more damage than they rectified. Avoid.Only giving 3 stars for these bearings - 1 star for each of the bearings that were actually usable out of the 5.2 bearings were absolute junk;One feels like the internal balls are damaged so it doesn’t spin properly & makes a horrendous noise when spun. The other feels the same but to the point it won’t even spin without considerable effort - hence both unusable.Luckily the other 3 are usable but even they needed a bit of work to get them rolling smoothly.Not even worth the effort to return these, luckily they were cheap.
