The pin member further includes an enlarged head portion positioned in the roller bore and forming an annular shoulder with the pin member shaft portion and the bearing comprises an outer race, a plurality of balls relatively mounted in the outer race, and an inner race formed in part by the pin member head portion and in part by a collar surrounding the pin member shaft portion and positioned against the annular shoulder of the pin member. The inner race is formed in part by an arcuate annular groove in the pin member head portion and in part by a complementary annular arcuate groove in the collar. Each arcuate groove defines approximately one half of the inner race and the annular arcuate grooves in the head portion and in the collar coact to define an included angle of at least 100.degree..
