As far as we know, you'll find a lot of variations between vibration bearings and plain bearings. In the following passages, the differences will likely be introduced in detail from the elements of look, the choice of material, the way to cope with the heating, internal clearance and results of usage.

What comes very first is the distinction of attributes among the two bearings. As for the vibration bearing, the diameter and the length of the rolling element are increased. To be able to reduce the functioning force from the roller element, the external rib from the retainer guides the roller. Meanwhile, to be able to enhance the operation from the roller, the internal rib is adopted to guide the roller. There is a tank hole within the diameter in the bearing so that the effectiveness of lubrication is fairly good. As for the plain bearing, the diameter and length in the roller are extremely little. The retainer is guided by the roller or inner circle. There isn't any tank hole within the diameter in the bearing to ensure that the effectiveness from the lubrication is fairly weak.

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

Thirdly, it really is turn to talk about the difference of heat remedy for both bearings. The vibration bearing is processed by the marquenching method and higher tempering. So this bearing is good in toughness and stability. As for the plain bearing, it's only processed by the frequent quenching method. So its toughness, shock resistance and thermal stability are fairly weaker.

Fourthly, you'll find variations about the internal clearance among the vibration bearing and the plain bearing. For the front one, its clearance is controlled in a really narrow variety in accordance with the requirement in the vibrating machine. For the latter one, its clearance is processed in accordance with the criterion group. The clearance could be narrow or could be big. Inside a word, the discreteness is rather big.

Final but not least, the result of use for the two bearings is distinct. When the vibration bearing is in operation, the noise is fairly low and meanwhile there's no early fatigue phenomenon. The service time is relatively long. As for the plain bearing, the noise is rather loud and also the service time is fairly quick.
