608-2RS Deep Groove Ball Bearings, ID 8mm x OD 22mm x Width 7mm Miniature Bearings, Double Rubber Sealed Ball Bearing Pre-Lubricated Chrome Steel Z2 Lever 20pcs

These new bearings are sealed to keep out water and liquids and have given a repaired toy a new lease of life.I had to repair an expensive broken adult toy which had seized and rusty bearings rendering it useless.These new bearings replaced the old bearings with zero hassle.These were such good value for money I bought way more than I needed. I now have plenty of spares...

The bearings come conveniently packaged in two plastic tubes. Tolerances are said to conform to ABEC 1 - I don't have callipers capable of measuring to that level of accuracy, but the diameters are all well within what I need (+/- 0.02mm). I'm not sure what level of loading these will take, but my projects are fairly small and undemanding, so these are ideal and will likely outlast the 3D printed housings I seat them in. The price seems good value, and you'd very likely see a much higher mark-up buying like-for-like from more dedicated engineering suppliers.

Overall for the amount of bearings you get I will not complain in the slightest for the price of these about that but one side note to take into account is for my usage I did need to soak these in some isopropyl alcohol which helped give a smoother motion to the bearings themselves for the prints I was going to use these in.When all is said and done excluding my slight issue these have worked wonders and if needs be in the future I will definitely get more would recommend but do take the advice of potentially needing to soak these for a bit as that is the only reason I’m giving these 4 Stars
