Engineering a crowded roller bearing setup for the big end

[lazylightning@mail.r]

With a 22mm I.D. you can upgrade to a much better "brand name" caged needle roller bearing. That was my original plan in the beginning: boring out the big end to 23mm and having a 22mm I.D. tool steel sleeve pressed into the big end to take a K16 x 22 x 10 caged bearing, but by the time i started to get the process moving forward with a tool maker, the Chinese were producing crowded needle roller big end bearings which have proved to be very reliable.

Given the I.D. dimensions of your connecting rod, you should be able to install a quality needle roller bearing.

The good titanium caged caged bearing could be a good temporary option for me...

From previous research, the INA-F.A.G bearings are very high quality items.

I do found K16x21x10 INA bearings on a supplier here in Brazil.
