The bearing size is perfect and the price is good at $18 a complete wheel/tyre/tube/bearing...pity!!
I am considering making some axle extension pieces maybe..which could also incorporate the motor mount..
I have also made some 150mm wheels that fit the skike tyre (150mm)- but again the cost for production is ludicrous..

my 5" wheels -and these will fit a standard skate truck. but im going to fit them to a MBS truck -i think.. to give the width and clearance on a deck.

Can the bearing seat in the skike wheel be milled narrower? How much too wide are they to fit a caliber axle?

yes the seat could be machined very easily but that means that all the wheels have to be machined..so defeating the point of being able to just buy a new wheel from anywhwere in the world...you see?
Hence why i am considering truck extensions...this also has the added benifit of giving a wider track width..for stability and wheel clearance..

DON'T BUY THESE:

If you are in the UK then these wheels on eBay are pretty good. £18.50 for two (with shipping):

Well, I just received a box of 6" pneumatic caster wheels! Sad to say they aren't exactly what I expected...The bearings in them are 10mm, and the outside diameter of the bearing is probably 28mm. I'll take a solid measurement a little later. It will probably be possible to machine a bearing seat/hub to fit in there and it will work on skate trucks width-wise. They have 8 spokes too which is going to be a problem with bolt spacing on my pulleys.

I'll let you know how it works out.

I'm sure, you can find bearings that fit that size wheel that would then fit that 8mm axle on longboard trucks. Does it fit on a pair of trucks? I would also probably sand down the sides of the bearings and/or CNC them off. Modify them to fit. What's the width of the entire bearing + center + bearing? Size of the entire width of the wheel?

We wont need to sand the bearings down as the width of the wheel with skate bearings fits skate trucks perfectly.

Just need to figure out bearings or spacers..the hub is 28mm wide and 8.5mm deep on either side. Think it'll use a standard bearing spacer. Found 8x28x9 bearings but they all seem to be in HK or China.

maybe it'll be better to just use the MBS bearing and wrap the axle with a spacer with a bit of loctite inside...?

I'm confused. Did that yellow bearing come with the wheel, or is that a 608 skate bearing?

Awesome psychotiller. Thanks again for those pictures. I'm definitely going to buy a set tomorrow morning LOL. What's the diameter of the bearing for that one? 8x28x9 exactly? Did you order your new bearings already?

Yeah psychotiller just used the skateboard bearings to show me the fitment. The yellow bearings are the standard 608 skateboard bearings.

I hope these 6 1/4" Pneumatic wheels ride well. That would be great news for being able to have a hybrid setup w/o having custom trucks to fit the MBS wheels!!!!!!!

Or using the skate bearings you have there, find an aluminum or pvc pipe with a thickness that would fit the gap and shave a ring off the end of the pipe?

There should be bearings that fit that entire diameter and have an 8mm hole. I believe, that's what hes getting.

Ok, so did the wheel come with bearings that have 10mm ID? Then maybe you could slip a spacer onto the 8mm axle to make it 10mm. To make sure the spacer stays put, you can coat the axle with Loctite before slipping on the spacer.

drmacgyver wrote:Or using the skate bearings you have there, find an aluminum or pvc pipe with a thickness that would fit the gap and shave a ring off the end of the pipe?


That's what I think psychotiller is looking to do. Either you use a 608 bearing and as you said, find something that will fill the gap on the OD of the bearing; or you can use the existing bearing (10mm ID according to psychotiller) and fill the gap on the ID of the bearing, like I proposed.

torqueboards wrote:There should be bearings that fit that entire diameter and have an 8mm hole. I believe, that's what hes getting.


There are bearings with 28mmOD, but not with 8mmID. MBS sells bearings size 9.5mm(10mm)ID x 28mmOD x 8mm Wide.

I see what your saying. If you can 10mm x 28 mm x 8mm then you could use 10mm axle trucks also https://www.muirskate.com/longboard/tru ... Truck.html. A bit pricer though. Would be nice if there was a bearing w/ ease lol

That's exactly what I was thinking. Then also get some washers with 8mm id/ 28mm od to cover/keep the pvc seated. Good Job drmcgyver!

Pediglide, The bearings that came in those wheels are unlike any that I have ever seen. Oddly crimped together. They have a hub as well that sticks out and makes them too wide for skate trucks anyway. The're up for grabs though if anyone wants them.

I was wondering could you take the bearing that comes with it. I think they said it was 3/8" = 9.525mm and either sand it down or lathe it to 8mm?
