SKF self-aligning bearing system
The industrial fan shaft challenge
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
