SKF Explorer self-aligning ball bearings

An alternative to spherical roller bearings for spreader rolls

Traditionally, spherical roller bearings have been used in supercalendar spreader rolls as they were the only self-aligning bearings available in the sizes required. The SKF range includes large self-aligning ball bearings with identical boundary dimensions to the spherical roller bearings. SKF self-aligning ball bearings will reduce friction considerably, helping mills to:
  • Extend relubrication intervals and reduce maintenance
  • Improve supercalender availability
  • Eliminate paper quality problems caused by bearing heat generation
