As far as we know, you will find plenty of differences between vibration bearings and plain bearings. Within the following passages, the differences will be introduced in detail in the aspects of appearance, the choice of material, the approach to deal with the heating, internal clearance and final results of usage.

What comes first will be the distinction of features among the two bearings. As for the vibration bearing, the diameter and the length in the rolling element are increased. As a way to decrease the functioning force in the roller element, the external rib from the retainer guides the roller. Meanwhile, to be able to improve the operation from the roller, the internal rib is adopted to guide the roller. There is a tank hole inside the diameter of the bearing in order that the effectiveness of lubrication is fairly good. As for the plain bearing, the diameter and length from the roller are very tiny. The retainer is guided by the roller or inner circle. There is no tank hole inside the diameter in the bearing to ensure that the effectiveness of the lubrication is fairly weak.

Subsequent, the choice of the material is various. The vacuum bearing steel is used inside the inner and outer circles and roller. So the vibration bearing is excellent in fatigue durability. Besides, since the aluminum, iron, manganese and bronze are adopted by the retainer, the bearing has much better strength, flexibility and wearing resistance. As for the plain bearing, its inner, outer circle, roller adopt the frequent bearing steel and its retainer adopts the brass. Consequently, this bearing is weak in strength and elasticity.

Thirdly, it is turn to talk about the difference of heat therapy for each bearings. The vibration bearing is processed by the marquenching approach and high tempering. So this bearing is excellent in toughness and stability. As for the plain bearing, it is only processed by the typical quenching technique. So its toughness, shock resistance and thermal stability are fairly weaker.

Fourthly, there are variations regarding the internal clearance among the vibration bearing and also the plain bearing. For the front one, its clearance is controlled within a extremely narrow variety based on the requirement from the vibrating machine. For the latter one, its clearance is processed in accordance with the criterion group. The clearance may be narrow or can be large. In a word, the discreteness is rather big.

Final but not least, the outcome of use for the two bearings is different. When the vibration bearing is in operation, the noise is fairly low and meanwhile there is no early fatigue phenomenon. The service time is relatively long. As for the plain bearing, the noise is rather loud as well as the service time is really short.
