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
