Excuse me, whether as thrust roller bearings tapered roller bearings, face to face or back to back installation
There are also spherical roller thrust bearings shaft ring and ring shaft, the bearing seat on the shaft ring, bearing seat is installed, roller shaft, shaft - ring......
Tapered roller bearing is needed to face to face or back to back the installation, because it can withstand axial load in one direction, the axial load to bear two directions must be two tapered roller bearing face or back-to-back mounting, and spherical roller bearings can withstand axial load in two directions, so there is no need to install or face back to back.
Do not need to face or back to back the installation, spherical roller bearing outer ring has two rows of rollers, common spherical raceway, two inner ring raceway, into a vertical angle with the axis of the bearing. Self-aligning spherical roller bearing can have very high meet, radial bearing capacity, heavy axial load can also withstand two directions.
