pillow block bearings

[Abstract]:
pillow blcok bearings

about the pillow block bearings Although its basic performance with deep groove ball bearings should be similar, but because of the bearing are mostly applied in mechanical rough, installation location is not accurate, the axis of the shaft with a hole to neutral, or under the condition of large axial length and deflection etc, and the bearing itself precision is not high, some structure is rough, so the performance of the actual performance comparison on the same specifications of the deep groove ball bearings to play quite a discount. For example, the outer spherical ball bearing with top wire is applied to the through shaft with large stiffness difference and deflection. The bearing with sealing ring on both sides can strictly prevent the invasion of dirt and has been loaded when leaving the factory

 

Outer spherical bearing

 

Outer spherical bearing

 

Proper amount of lubricant, do not need to clean before installation, do not need to add lubricant, when the screw screw on the protruding end of the bearing inner ring is tightened on the shaft. The allowable axial load shall not exceed 20% of the rated dynamic load.

 

The performance of the outer spherical ball bearing with eccentric sleeve is basically the same as that of the outer spherical bearing with top wire, except that the top wire is not on the inner ring, but on the eccentric sleeve. The inner hole of the outer spherical ball bearing is a cone hole with a taper of 1:12, which can be directly mounted on the cone shaft or mounted on the optical shaft without shaft shoulder by means of a compact bushing, and the bearing clearance can be adjusted.

 

Outer spherical bearings are preferred for applications requiring simple equipment and parts, such as agricultural machinery, transportation systems or construction machinery.

 

It is mainly used to bear the combined radial and axial load with radial load as the main part. Generally, it is not suitable to bear the axial load alone. This kind of bearing can be installed with inner ring (with full set of rollers and retainer) and outer ring respectively. This type of bearing does not allow the shaft to be tilted relative to the housing. The size of the axial clearance of the bearing has a great impact on whether the bearing can work normally. When the axial clearance is too small, the temperature rises higher. Bearing is easy to be damaged when axial clearance is large. Therefore, special attention should be paid to adjusting the bearings during installation and operation
