Locating and non-locating bearing positions

Housings for paper machines are available for both the locating and non-locating bearing positions:
  • Housings with the designation suffix F are designed to accommodate spherical roller bearings in the locating bearing position on the drive side.
  • Housings with the designation suffix RA are designed for CARB toroidal roller bearings in the non-locating bearing position on the front side.
SKF recommends using a spherical roller bearing on the drive side and a CARB toroidal roller bearing on the front side (→ The SKF self-aligning bearing system). However, other housing/bearing combinations are also available (table 1).
The extent to which a CARB toroidal roller bearing can accommodate axial displacement due to interference with the seal can be calculated. For assistance, contact the SKF application engineering service
