uxcell MR105-2RS Deep Groove Ball Bearings 5mm Inner Dia 10mm OD 4mm Bore Double Sealed Chrome Steel Blue Seal Z2 20pcs

Used for rear carrier bearing on my 1/10th scale rc crawler

Perfect. Exactly what I wanted! Not very tough, but how tough can balls that small really be anyway? Am I right?I use them in knives, and they work perfectly. Well machined and inexpensive. Fast delivery. 💯

Nice bearings for random projects, good seals and low friction

Used for a joystick gimbal. This was my son’s project, so I’m going to have to take his word for it.

Nice

We used these for rc cars and they worked as expected. Metal shielded would be a little better for the wheels as tangled up grass can often wrap around the axles and damage the plastic shielded type but these are very affordable.

These are specified at 10mm x 5mm x 4mm but when measured, the I.D. is just a bit under at 4.86mm. The carbon fiber rods I am trying to use just wont fit. If your tolerances are tight, you may want to try another bearing.

so I bought this with the impression that the inner diameter would be 5mm but ut turns out to be .15 mm smaller and while I could forgive something around 0.05 off that is far too far and with no range of inequality I think something needs to be showing saying it will not be 5 mm exact and this was ensured with 2 different calipers
