To be honest, I’m not trying to hold back on technical details. At its core, this is simply an integrated bearing structure, so the overall concept itself is quite straightforward. What we’ve been more cautious about sharing at this stage a

Lol, Thanks! This small engineering upgrade ended up delivering a surprisingly huge improvement. The mass-production version will be priced under $100 — the precision is too high for stamping, so every part has to be CNC-machined. That make

It’s essentially a 2mm-thick micro-bearing in the shape of a ring, so anything getting inside would be a serious issue. The good news is that after sealing, the only opening is a 0.1mm side gap between the inner and outer rings — and in nor

I only wanted to leave an external reference on this very old platform — it now lives on the About page, and that’s enough for me. And as for customers: we don’t really welcome people who feel overly self-important.
