The use conditions and environmental conditions of spherical roller bearings


Correctly grasping the location of the Spherical Roller Bearing in the mechanical device and the conditions of use and environmental conditions are the prerequisites for choosing a suitable spherical Roller Bearing. For this, it is necessary to obtain the following data and information:

(1) Function and structure of mechanical device

(2) Where to use spherical roller bearings

(3) Spherical roller bearing load (size, direction)

(4) Rotation speed

(5) Vibration and shock

(6) Spherical roller bearing temperature (ambient temperature, temperature rise)

(7) Ambient atmosphere (corrosiveness, cleanliness, lubricity)

Rigidity of spherical roller bearings

The rigidity of a spherical roller bearing is determined by the amount of elastic deformation that occurs when it bears a load. Under normal circumstances, this amount of deformation is very small and can be ignored. However, in some machinery, such as machine tool spindle systems, spherical rollers The static stiffness and dynamic stiffness of the sub-bearing have a great influence on the characteristics of the system. Spherical roller bearings have higher rigidity than ball bearings. Various types of bearings can also improve their rigidity to varying degrees through proper "preloading".
