I know it would mean changing a standard skating industry has been using for the past 30 years, but it would advantage longboarding enormously. Longboarding oftenly means bad pavements, rough surfaces, sometimes offroad which kills any good bearings in a matter of days. Now the bigger the bearing, the bigger its balls which means bigger tollerance, therefore longer life.Not to mention faster speeds.It would require a new line of trucks and wheels but I think it would be worth it.
It isn't needed. Bearings last months, years even, as long as you take care of them. I have a set of bearings that I've used for over 8 years, they still work great. If you're killing bearings in a couple of days, you're doing it wrong. And bearings don't affect speed, so long as they're clean/lubed. Bigger bearings would mean bigger wheel hubs, which means either less urethane on the wheel (less sliding per dollar), or bigger wheels (wheelbite becomes an issue, and bigger wheels don't feel very good to some people). It's pointless and unnecessary.
just clean your bearings. not that hard. they do make 10mm bearings for 10mm axles on precision trucks though.
