Advantage of the Cagerol ® End-Relieved RollerAdvantage of the Cagerol ® End-Relieved Roller Cagerol® bearings utilize rollers with end reliefs to achieve increased
bearing ratings
Up to a 20% increase in basic dynamic rating over uncrowned roller designs
McGill Design provides for higher published load ratings than the competition
