What are the basic features of mounted bearings?

The radial bearing and the seat of the mounted bearing are assembled, and there is a base plate for mounting screws on the support surface parallel to the bearing axis.

What is the dismantling method of the mounted bearing?

1. First use an Allen wrench to loosen the locking screw on the eccentric sleeve of the mounted bearing, then insert a small iron rod into the countersunk hole on the eccentric sleeve of the upper cover, and loosen the eccentric sleeve against the direction of rotation of the shaft.

   
   

2. Loosen the screws with which the bearing housing is fixed. Remove the mounted bearing along with the bearing housing from the shaft. Note that before removing the bearing housing at one end of the shaft. The bearing seat screw at the other end of the shaft should be loosened to avoid damage to the bearings at both ends.

What are the components of mounted bearing?

mounted bearings generally consist of four parts: inner ring, outer ring, rolling element and cage.

The function of the inner ring is to interact with the shaft and rotate with it;

The function of the outer ring is to interact with the bearing seat and play a supporting role;

The mounted bearing is designed to distribute the rolling elements evenly between the inner ring and the outer ring using the cage, and its shape, size and quantity directly affect the performance and service life of the rolling bearing.

The cage can distribute the rolling elements evenly, prevent the rolling elements from falling down and guide the rolling elements so that they rotate for lubrication.

What are the basic features of mounted bearings?

The basic performance of mounted bearings should be similar to that of deep groove ball bearings, but since these bearings are mostly used in relatively rough machines, the installation and positioning are not accurate enough, the axis alignment between the shaft and the seat bore is poor, or the shaft is long and the deflection large. In other cases, the accuracy of the bearing itself is not high enough and some structures are relatively rough, so the actual performance of the deep groove ball bearing of the same specification should be marked with a significant impact. Example: The outer dome ball bearing with upper wire is used in the continuous shaft with large stiffness difference and large deflection. This type of bearing has sealing rings on both sides, which can strictly prevent the penetration of dirt. It was filled with a reasonable amount of lubricant before leaving the factory and does not need to be cleaned before installation. There is no need to refill lubricant when the upper screw is attached to the shaft at the protruding end of the bearing inner ring. The permissible axial load shall not exceed 20% of the rated dynamic load.
