Hey Guys,
After researching the net, I’ve found that these are missing really. They do not exist AFAIK. Maybe I’m wrong, but couldn’t get a hold on them.
If you wish to use 12mm trucks with street wheels, your options are limited.
Therefore, I’ve decided to try and manufacturer them and really would like to see if there is some sort of demand for it.
Materials, 304 stainless steel rings +Si3N4 ceramic balls (may change), lubricated.
The final cost per pack (8 bearings) will be around 50-80$ (not final).
[UPDATE]
The bearings are almost ready, once we’re ready I will publish the final price. I know there is a discussion about their ability to last. These are going to be robust! BUT frankly, bearings are not meant to last forever, so anyhow we are aiming for a price range that is considerably affordable to be able to swap if needed. They will be priced like this not because we want to be rich (we want to, but no like this ), it’s because they are not standard and hard to manufacture, so please keep that in mind.
I saw some company on Instagram posted tb110 on matrix 2 trucks on a propotipo. Idk what they used. I remember it being expensive… So they may exist… Time to do some digging.
That was Skate Kastle, @kevingraehl was killing them in the comments. Meant for Lacroix Prototipos and was $300 I believe for pulleys, belts, risers, and bearing
21x12x7mm, available in both RS and ZZ versions. There are thinner models available too, how about making a batch of custom inserts to fill the 22mm total ?
Will be straightforward compatible with wheels and trucks, you do pressfit and you’re up. No friction. And free choice of existing bearings so probably cheaper alternative in the end.
Don’t know if there are versions with in-built spacer tho (à la Zealous)
That is also a good option, however, it may be tricky to push them to metal core wheels (not many in the market but there are such …) that will require high precision and tolerance so not sure how this will work though with an insert.
How about nylon or Teflon inserts? Self lubricant for the pressfit and will compress just enough for the fit. Should keep it’s integrity and shape under load.
