A Grade 3 ball means that the ball is 3/1,000,000” tolerance of sphericity, and so is extremely round. In fact, the races of any bearing can't come close to this level of precision in their trueness, but every component being closer to perfect helps decrease friction. Another feature of Grade 3 is surface finish, which in this case is free of scratches or scuffs, and to a
