Compared with traditional cylindrical roller bearing designs for wind-gearboxes we are achieving increased load capacity. SKF high capacity cylindrical roller bearings design is optimized for higher load ratings to achieve a higher safety factor, extended service life and higher power density.
Compared with full complement bearings we are eliminating the risk of roller to roller smearing. Other design improvements reduce the risk of cage slip, fretting corrosion, ring creep and flange fracture. These improvements result in enhanced reliability.
Also, these bearings are designed for improved lubrication with better oil film build up, resulting in reduced smearing risk and wear.
