摘要

The roller bearing (1) has radially stacked race rings (2,3,4), where each race ring has a raceway (8,9,10). The race rings are made of plastic, where metal inserts (5,6,7) are firmly introduced in the raceways of the plastic race rings. One of multiple profiles (20,21,22) is formed by a rotating cam profile.
