FAG Barrel roller bearings are single row, self-aligning roller bearings. They comprise solid outer rings with a concave raceway, solid inner rings with two ribs and a cylindrical or tapered bore as well as barrel rollers with cages. In FAG 20207-TVP Barrel roller bearing, Solid window cages made from glass fibre reinforced polyamide are indicated by the suffix TVP. And suffix C3 means Radial internal clearance larger than normal. Barrel roller bearings are not sealed.
