SKF 319301 cylindrical roller bearing. Single-row cylindrical roller bearing carrying very heavy radial load and moderate speed. Standard NU, N, NJ and NUP designs differ only in whether the rib is on inner ring, outer ring, or both — this sets the axial-guidance capability (NU floats axially, NJ takes axial in one direction, NUP in both). Cage execution ECP (glass-fibre reinforced polyamide 6.6) is standard up to bore 100 mm; ECM (machined brass) above. ISO 492 Class Normal. Bore diameter d = 12 mm per ISO 15.

ISO 15 boundary-plan interchange — the numeric bore-code block is portable across every ISO 15 bearing manufacturer (SKF, Timken, NSK, NTN, FAG, Koyo, NACHI). Confirm suffix compatibility on cage, seal, clearance and precision class before substitution.
