Headset Cartridge Bearing Question

I was looking at my headset cartridge bearings and noticed some writing on the sides: TH MR168 1-1/8 45*X45* I6.

I understand the meaning of the "1-1/8" and the "45*X45*" but what do the other letters and numbers mean?
  • TH
  • MR168
  • I6
Thanks.

TH is likely the manufacturer, I forget who but there's an Asian company with T and H in their name (IIRC).
MR168 is likely their part number
I6 is likely a made on date. Andy
