Pendulum roller bearings are double-row, self-holding units consisting of solid outer rings with a spherical raceway, solid inner rings, and barrel rollers with cages. The inner rings have cylindrical or tapered bores. The symmetrical barrel rollers adjust freely on the spherical outer ring raceway. This compensates for shaft deflections and misalignments at the bearing seating points. The different versions are designated by specific suffixes: A = modified inner construction, B = modified inner construction, E1 = reinforced version (standard), K = tapered bore 1:12, K30 = tapered bore 1:30, M = solid brass cage, TVPB = plastic cage. Special feature: solid brass cage, open design.
