Appropriate bearings

SONL plummer block housings are designed for
  • Self-aligning ball bearings in the 22 series
  • Spherical roller bearings in the 222 series
  • CARB toroidal roller bearings in the C 22 series.
The housings are available for
  • bearings with a tapered bore on an adapter sleeve and on smooth shafts – shaft diameters 75 to 220 mm (fig 1) or 2 15/16 to 8 15/16 inch respectively
  • bearings with a cylindrical bore on stepped shafts – shaft diameters 85 to 200 mm (fig 2).
For high speeds and high operating temperatures, where SONL plummer block housings are typically used, SKF recommends using bearings with a larger internal clearance (C3).
