NTN 2308C3 is a double-row self-aligning ball bearing with a cylindrical bore, 40 mm bore by 90 mm outside diameter by 33 mm width. Two rows of balls run on a common spherical raceway ground into the outer ring, so the inner ring and ball complement swivel inside the outer ring. Open on both faces, pressed steel cage, C3 internal clearance.
23 — double-row self-aligning ball bearing dimension series.
08 — bore code, 08 × 5 = 40 mm.
C3 — radial internal clearance greater than normal.
No K suffix — cylindrical bore.
