No info whatsoever obtained from knowing what is stamped, sigh... Stamped as follows. " B SCE109 USA " Annoying at best... Maybe the drive side has more info? SCE109 almost sounds like a bearing ID number?
And it is.. A needle roller bearing. Forgot to mention the INA also stamped on it... Apparently you buy a couple of these, and pop them into these cups... Still bizarre and never seen or heard of this bearing style in a bottom bracket before.
