SKF NU/NJ 4 Series Cylindrical Roller Bearings

SKF NU/NJ 4 Series Cylindrical Roller Bearings

SKF single row cylindrical roller bearings of the 4 dimension series in NU, NJ, NUP and N designs, as listed in the SKF General Catalogue. Bore diameters 30-120 mm.

Key features

  • Separable design: inner ring and outer ring with roller and cage assembly can be mounted separately
  • NU and N designs accommodate axial shaft displacement; NJ locates in one direction, NUP in both
  • High radial load carrying capacity with line contact rollers
  • Smaller sizes as SKF Explorer bearings (EC design) with polyamide (P), steel (J) or brass (M, MA, ML) cages
  • Catalogue table also lists reference speed and limiting speed for each size
