New bearing cage extends life of cylindrical roller bearings by more than 20 per cent

Schaeffler has introduced new FAG high capacity cylindrical roller bearings that have a new sheet steel cage, which enables a much more compact design compared to a conventional solid brass cage. The slimline cage leaves space for at least one additional rolling element in the bearing, which increases the load rating significantly. The high capacity bearing has a significantly lower friction than full complement cylindrical roller bearings with maximum basic load rating. The self-retaining cage also simplifies bearing mounting because the rolling elements are retained even when the ring is removed. The cage comprises two cage rings lying one inside the other and joined together. The crosspieces of the inner cage guide the roller elements and retain the roller elements in the bearing, even when the bearing ring is removed. The special geometrical shape of the cage pockets improves lubricant flow, which reduces friction and prevents damage to the bearing.
