Rolling the type selection

When you select the type of rolling bearings, bearing the working load should be considered (size, nature, direction), speed and other requirements.
1) The speed is high, the load is small, the requirements should be selected when the ball bearing high precision rotation; low speed, load impact load is large or the selection of roller bearings.
2) the bearing by both radial and axial load, generally used in the angular contact ball bearings or tapered roller bearings; if a large radial load, axial load is small, can use deep groove ball bearings; and when the axial load large radial load hours, can be thrust angular contact ball bearings, four row cylindrical roller bearing or a combination of structural choose thrust ball bearings and deep groove ball bearing.
3) When all kinds of bearings, the tilt angle between the outer ring should be controlled within the allowable angle of deflection value, otherwise it will increase the additional load bearing and reduce life expectancy.
4) the larger shaft stiffness requirements, should use double row ball bearings, roller bearings or four-point contact ball bearings, the load is large or larger impact force may be employed on the same point double column or row roller bearings . Bearing system rigidity and high rotational accuracy can be increased shaft, reducing noise and vibration.
5) For ease of installation and removal, and adjusting the gap often used in inner and outer rings separable separation of bearings (such as tapered roller bearings, four row cylindrical roller bearings).
