SKF 63 Series Deep Groove Ball Bearings

SKF 63 Series Deep Groove Ball Bearings

SKF single row deep groove ball bearings in the 63 series (open, shielded and sealed). Simple, robust, non-separable bearings for radial and axial loads at high speeds.

Key features

  • Single row, non-separable design with deep uninterrupted raceway grooves
  • Carries radial loads and axial loads in both directions, suitable for high speeds
  • Boundary dimensions to ISO 15:1998
  • Open bearings plus shielded (Z, 2Z, RZ, 2RZ) and sealed (RSL, RSH, RS1 and 2-side) variants where listed
  • Sealed and shielded bearings are greased for life; SKF Explorer sizes marked in the catalogue
