Spherical Roller Bearings

Spherical roller bearings are double row units comprising solid outer rings with a concave raceway, solid inner rings and barrel rollers with cages. We stock both the plain (symmetrical) bore (EAW33) and taper bore (EAKW33).
The symmetrical barrel rollers orientate themselves freely on the concave outer raceway. As a result, shaft flexing and misalignment of the bearing seats are compensated.
