IIRC the Tange Passage is actually a bit shorter than 31mm stack, perhaps in the 28 to 30mm range but that might be just my (good) luck or running without any lock washer...but some of the cheepo sealed bearing HS ( which use thin sealed cartridge bearings on T&B) you find from Chinese sellers might have comparable short-ish stack heights, but often they do not publish details like that in the ads, plus aren't too clear about which are for threadless, threaded or the steerer diameters. I think the thin bearings used permit final stack heights to be lower than the "balls in cage" styles.
So read extra carefully and "buyer beware".
But they often are quite cheap (like $20 or under) and a few have surprised me with better than expected quality, additionally most use a split (Alu alloy) crown race since the part doesn't make contact with balls, and therefore will fit both 26.4 & 27.0 fork crown races
