SKF BC1B322770A/HB1 — Cylindrical roller bearing
SKF · Bearings & Power Transmission · Cylindrical Roller Bearings
SKF BC1B322770A/HB1 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 = 350 mm per ISO 15. Designation follows the ISO 15 / DIN 623 alphanumeric convention where the numeric block encodes the dimension series and bore code; suffixes after the numeric block declare cage, closure, precision, clearance and lubricant execution. Genuine SKF supply carries the SKF logo etch on the outer ring face and hologram-authenticated packaging.
