The MEI design "PA" series Trunnions are
shown here with the
Full Compliment Universal needle bearing. MEI is the only STUD mounted
rocker manufacture to have ever offered a drilled core and dual flat mounting
face, making the part both lighter and stronger, thanks to removal of the
"sheer" edge found on the bottom side of the adjusting stud hole of other
trunnions. Increased strength comes from the dual surfaces (ID & OD) created by
drilling core out, much like rifle drilled axles on differentials.
