C3 — radial internal clearance greater than normal.
A barrel roller bearing carries radial load and self-aligns through its spherical outer raceway. It is a single-row design with very limited axial capacity, distinct from a double-row spherical roller bearing of the 213 series in the same envelope. The tapered bore mounts on an adapter sleeve or a tapered journal.
Bore Type: Tapered 1:12. Adapter sleeve: H308 (35 mm shaft seat).
Unit Quantity: 1 Pc.
Straight-bore sibling in the current Schaeffler range: FAG 20308-TVP-C3. The 213-series double-row spherical roller bearing 21308-K shares the envelope but is a different bearing type.
