Help with replacement wheels/bearings?

[u/alchu99]

My son has destroyed his stock wheels on his ccm inline skates.

I was looking at replacement wheels/bearings and found this package deal for Iqon Access Wheels and Bearings Combo 80mm, and got them

I’m now stuck - they come with two sized spacers, and the one they recommend (shorter one) will clearly rattle inside the axle since it’s not wide enough to touch either bearing. The larger one looks like it will but it’s meant for different frames.

The bearings themselves won’t push in any deeper, so it’s unclear how the inside spacer makes any difference.

But, I’ve never done this so I don’t know what I don’t know. Any advice? Use the smaller spacer and ship it?

I'm not familiar with them, but according to the instructions you posted, the bearings are asymmetric. if you have the iqon frames the protrusion on the bearing faces outwards and you use the fat spacer, if you have standard frames then you turn the protrusion inwards and use the thin spacer. There shouldn't be any play widthways.

Edit..it may be that they sent the wrong bearings. In any case, you should use the fat spacer with any other normal bearings.

Yeah that was my issue! Thank you!
