Default spacers

I received some new spacers for my hubless wheels. They did not have them before. The ID is the same as the bearing and when not put on the axel will float inside the wheel. Is this how it should be? Also, I received speed washers with the spacers, do I need to put one on the axel first or are they needed at all.

I apologize for not having pics, the site I use won't imbed the pics, I'm working on that.

Imbedding the pictures requires the pix to be on a hosting service like photobucket. Anyway the brand and model of the wheels would be helpful before I try to give you advice.

Radar Zen are the wheels in question.

Default Pics now available

See that the ID of the wheel and the OD of the spacer are no where close. So the spacers float until an axel is pushed through. Also, what do I do with the speed washers, are those for fine adjustment of the spacing?

Thanks for the pic. If the wheel comes with spacers most likely they will fit properly. Wheels that do not have hubs like to have spacers. They make the whole wheel / bearing assembly more rigid.

The spacer is not intended to fit the ID of the wheel since it locates on the axle. A good fit on the axle to align the spacer is not even essential since one can get away with running 8mm spacers on 7mm axles.

As far as the "speed" washers?? Those look to be intended for use between bearing and the truck just in case the truck housing is not smooth where the bearing contacts it. Use them at your discretion.

got the spacers and they are just slightly too long. They don't sandwich the wheel nicely and they don't leave any threads on the axel when tightened. So can an armature machine this down. This is a total guess, but can I chuck it up on a drill press and set the depth just so. Mount sandpaper on the table part, slowly turn it down? better solution to a non-machinist?

Interesting idea. I'd give it a shot.

Default arrrrrrg.

I decided to get new spacers measured them out. I measured the 10 mm on the wrong side. The new spacers are exactly like the old. Arrrrggg again. I can't skate the outdoor wheels. I'm still figuring a way to machine them down.

Default Finally found a way to cut the spacers

I conferred with maintenance at work. The maintenance boss designed a jig made mostly of wood. I came up with this from stuff around the house. It will need a bit of cleaning up but it cut nice.

no offense but you have just destroyed the spacers,
not only do they need to be the right length they need to be cut concentric,
or perfectly square, you home made rig is not going to do that.
send to a machine shop to have the spacers milled or turned to the correct length.
tighting down on those home cut spacers will cause your bearings to bind.

I think I will have to get un-cheap and get some decent outdoor wheels. I prolly went too soft anyway since I'm planning on skating a swept court or my indoor concrete floors. I think I need hubs on soft wheels so my fatness doesn't distort the wheel clear to the hub. The spacers were like 50 cents for the lot. I can give them to my local long boarders as they fit their wheels.
