Does anyone know what the coller is for on the rear wheel spacer is for it doesn't look to locate into anything, I have bent one side a bit when removing it and wondered if I needed a new one. Cheers. I should say it's the internal spacer that goes inside the hub between the two wheel bearings.

This is to prevent a sideways force being exerted on the bearings.

I think it's to keep the spacer roughly in place while you press the second bearing into position & help keep it inline with the two bearings. The collar can't be an exact size because it remains stationary while the wheel spins so would wear a groove on the inside of the wheel hub.

You may be right it's very thin so you wouldn't have expected to do anything structural.

It's there to keep the spacer tube in line with the centre of the bearings whilst fitting the wheel spindle.
Without it the spacer tube could move out of line and either prevent the spindle passing through the wheel or it could drop fully clear of the bearings in to the hub which would then allow the bearings to bind and quickly fail once the spindle is tightened.
