Does anyone knows the specs of the ZT 0393 bearings, that is: inner diameter (ID), outer diameter (OD), thickness (TH) and ball diameter. The 0393 takes Hinderer pivot so the ID should be the same, 1/4", please let me know if it's different. The cage TH doesn't really matters, it just needs to be smaller than the ball diameter. I could do with a rough measurement ID and OD but I needs the ball diameter to be precise.
Thanks
