The White Industries hub has two large bearings in the hub shell, and three more under the titanium freehub. It's pretty strong.
The bearings are replaceable with a bearing press, that most bike shops should have. No other special tools are needed: see the hub service pdf.
It looks sharp in polished aluminum finish:

On the White Industries H3 hub:
Ron: This has been the most popular hub I use. It's strong, has a large bearing capacity, it looks nice, has a Ti freehub, and the price is good. I think it's the only hub in this review that has a steel axle. The weight is also higher than others in this review, but it is still not bad. It's easy to build solid wheelsets with the H3 that are in the 1360-1500g range, which makes them lighter than comparable factory wheels that are much more expensive.
This is probably a good place to mention something about shell materials. White Industries is one of the few that uses the common and boring 6061 aluminum alloy for their shells (Alchemy is another). Most manufacturers use a very high strength alloy, and at first glance this seems like a good idea. Stronger is better, right? In this application though, I think that 6061 is better choice. The reason is that 6061 has higher corrosion resistance, and more importantly resistance to something called "stress corrosion cracking". The spokes exert concentrated and variable forces at the holes in the hub flanges, and high strength is a less important factor than ductility and corrosion resistance. Hubshells normally fail when cracks develop and grow at the spoke holes, and the flange eventually pulls away. Unlike many manufacturers White Industries hubs have no restrictions on lacing and spoke tension, yet I've not heard of a single one suffering a flange failure. Another advantage is that the softer alloy will deform more readily providing better support for the spoke in the flange. It is also one of the reasons why the silver hub looks so pretty... it is polished bare metal with no anodizing... yet is still corrosion resistant enough to stay shiny in most environments.
