Cylindrical roller bearings features

1 roller and raceway contact or repair offline contacts, radial load capacity, suitable to withstand heavy load and shock load.
2 small friction coefficient, suitable for high speed, speed close to deep groove ball bearings.
3.N type and NU type can move axially, to accommodate misalignment due to thermal expansion or of the shaft and the housing due to changes in relative position, can be used for supporting the free end.
4 pairs of shaft or housing bore machining higher, bearing outer ring axis relative deflection after installation should be strictly controlled to avoid contact stress concentration.
5 inner or outer ring detachable, easy installation and removal.There are small axial load, the choice of deep groove ball bearings, angular contact ball bearings, tapered roller bearings and self-aligning ball or spherical roller bearings; when the axial load is larger, the larger the contact angle can be used angular contact ball bearings and tapered roller bearings, or use radial bearings and thrust Precision bearing together, which in very high axial loads or special requests, especially when there are large axial rigidity adapt appropriate.
b. Permissible speed
Because different types of bearings are very different. Generally, the friction is small, less heat bearing suitable for high speeds. Rolling in the design should strive to lower the speed limit working conditions.
c. Rigidity
Bearings under load, the bearing rings and rolling elements contact point will produce elastic deformation, the deformation is proportional to the load, the ratio determines the size of the bearing stiffness. Generally by bearing preload to improve the rigidity of the bearing; addition, the design of the bearing support, considering the combination and arrangement of the bearing can also improve the support rigidity of the bearing.
