From Rotary Wing Forum:-

"I just happened to see your post. Are you seeking the part no. for the "needle bearing" or the bearing for the "hat bushing?"

I thought I may have had the needle bearing number. I pulled out some old notes I had, and I have two numbers noted in two different places for the tower "needle bearings."

One is...B128, and the other is...BRG TOR- IR128.

If you have a bearing shop handy there, you could check their catalogue?!"

B128 has 0.75" ID, 1" OD, 0.5" width, Full compliment, Open end.

IR-128 Inner ring has 0.75" bore, 1" OD, 0.5" width.
