SKF self-aligning bearing system

The industrial fan shaft challenge

Self aligning fan shaft solution
Industrial fan shafts usually have separate bearing locations, with one bearing in the locating position and one bearing in the non-locating position. With spherical roller bearings on both sides, shaft elongation is often accommodated by the bearing in the non-locating position by having a loose outer ring fit.

The SKF solution

Designed to overcome this problem, the SKF self-aligning bearing system for fan shafts incorporates an SKF Explorer spherical roller bearing in the locating position and a CARB® toroidal roller bearing in the non-locating position. The system accommodates misalignment and shaft elongation, virtually without friction. Benefits include:
  • Possibility of higher speeds, resulting from less heat generation
  • Reduced energy consumption, resulting from reduced friction
  • No induced internal axial forces for reduced operating temperatures
  • Improved lubrication, resulting from lower bearing operating temperatures
  • Reduced risk of imbalance, resulting from lower vibration levels
  • Reduced maintenance costs, resulting from extended relubrication intervals
  • Extended bearing service life
  • Reduced vibration and noise levels
  • Increased reliability
