Sorry to bother you again with yet another question – I’m somewhat skating-obsessed at the moment:
Have any of you ever used axle sleeves – like these:http://www.fastgirlskates.com/roller-derby-skates/pc/Axle-Sleeves-52p95.htm – to use 8mm bearings on 7mm trucks?
I’m seriously thinking about buying a new slalom set-up now (T2 Lazer plates as recommended by you in my slalom thread & Risport Etoile boots), and if possible I’d like to still use my old 8mm bearings that are in all my wheels now (simply because they aren’t all that old and still good). I saw some axle sleeves in American online shops, and am wondering if they could be the answer to my problem?12 avril 2010 à 12 h 00 min #265544
I didn’t know that somebody had the idea to build those sleeves.
To be honest, that is a f#@king good idea.
If you have the opportunity to order it, will you write an article for 100% Quad ?12 avril 2010 à 13 h 31 min #265545
Sure, I will, if it’s okay in English.
So far, it’s not looking good for me being able to order them from the US, though – we’ll see if I find a shop that’ll do it without monster shipping costs.
On the American forum some people say they’re okay to use and one or two people hate them.12 avril 2010 à 14 h 07 min #265546
« Hate them » ? Why ?12 avril 2010 à 15 h 15 min #265547
Uhm, extra weight and one forum member says they don’t really fit.
Another skater says this:
I have some and use them, but I don’t like them at all.
I can’t get the axle nuts the way I like them, the wheels don’t fit right, and the ride is rough because nothing fits right and the sleeve rotates on the axle some.
Some also say they’re using them and everything is working fine, though.
Postage is $ 16, however, from the shop I asked, so I guess I’ll just get 7mm bearings and spacers when I buy the skates – it’s just not worth it. Unless, of course, lots of other skaters in Europe wanted them and we could do a ‘bulk order’.24 juillet 2010 à 21 h 53 min #265548
Why do two of the top performing outdoor wheel manufacturers – Pacer and Roll-Line bundle spacers with their wheels?
If a spacer fits properly into the hub and you can just fully tighten your axle nuts down against the inner bearing races, the bearings are going to work optimally. They are going to be more likely to stay properly set and aligned with each other under dynamic loading.
Not all hubs are accurately molded/machined and sometimes the spacers do not dimensionally match up correctly with the hubs. When this happens, spacers are a problem and should just be dumped or replaced with proper sized ones. Unfortunately, the variations in hub dimensions and spacer dimensions often conspire to make their use extremely difficult to accomplish successfully. However, when you finally do get all eight wheels set up correctly with spacers and eliminate absolutely all wheel wiggle from every wheel, it is a truely satisfying experience!

I agree, perfect analysis of a current issue.
To sum up : skate without spacers 😉30 juillet 2010 à 3 h 25 min #265550
To use 8mm bearings on a 7mm axle can be accomplished using rectangles of metal cut from the faces of sardine cans. You just cut it with strong scissors to a length that goes about 2.5 times around the 7mm axle. Cut the width just narrower than the space between the bearings.
Start with rectangle a bit longer than needed. Roll it up on a rod that is smaller than 7mm initially and the spring back will match closer to 7mm.
Test fit and trim length back until it just fills the gap.
Enjoy your sardines too!

What a f#*@ing good idea !
