Aligning Angle
Maximum permissible misalignment angle is about 2º under general service conditions. If the aligning advantages of this bearing type are to be realized, care must be taken to provide clearance for parts in the surrounding structure.
Minimum axial load
To prevent damage caused by sliding motion between the rollers and raceway, spherical roller thrust bearings must be subjected to a load more than the minimum load, Fa min.
Lubrication
Because there are many sliding surfaces in E type Spherical Roller Thrust Bearings (cage-to-guide-sleeve and roller-ends-ti-rib), oil lubricant (not grease) should be applied.
Safety-factor
The safety-factor "So" must be over 4.
