The ultimate reusable sealed bearing Square Tapered Bottom Bracket

[GuyBoden]

Is this the ultimate reusable sealed bearing square tapered bottom bracket?

The major advantage is that I can buy new sealed bearings when they wear out and install them, so the BB is reusable.

Looks good, but depends on the bearings and how long they last. Ultimate fit and forget are UN71 and UN91 BB's

Yes, but sadly no longer manufactured as well as ubiquitous long lasting Shimano BB-UN55.

I'm using "Made in Japan" bearings.

How would you seal them?
Are the bearing seats adequate?

The bearings are the same diameter as the axle and cups, the seals are integral to the sealed bearings.

PS who makes it ?

The axle is suntour, the sealed bearings are Japanese, the other parts are Miche, so it's a pic'n'miche.
