Anti-Friction. Plain bearings have surfaces that rub together, like sleeve bearings. In roller bearings and ball bearings, the surfaces roll and do not (that is, should not) slide. If they slide they destroy themselves quickly.

What is better a ball bearing or a speed bearing?

Metal rollers are typically sold as congregations and are essentially supplanted as units. Roller orientation can frequently be dismantled and the roller transporter and rollers, or the external or inward races, supplanted exclusively. Back tire drive vehicles utilize such plans for the front wheels. The upside of this plan is that the races can be contracted fit onto shafts and into lodgings to make perpetual gatherings without gambling harm to the actual rollers. Single-column metal rollers are normalized and can be utilized conversely among makers. Roller direction are less-officially normalized so a specifier needs to counsel a maker's list to choose one proper for the application. Moving component heading are fabricated with a specific measure of inside leeway. Any misalignment that only prods a ball out of position and eliminates this interior freedom ought not have a lot of impact on the existence of the bearing. Roller direction are more touchy to rakish misalignment. For example, a metal roller running at moderate speed with a genuinely free fit may work effectively with precise misalignment as high as 0.002 to 0.004 in./in. between the bearing and shaft. A tube shaped roller bearing, in examination, may be in a difficult situation if misalignment surpassed 0.001 in./in. Makers will by and large give satisfactory scopes of precise misalignment for their individual bearing.

How is friction reduced in a rolling bearing as compared to a plain bearing?

In case of rolling contact bearings there is either point contact or line contact between rolling elements and races of the bearing depending on whether it is ball bearing or roller bearing... In case of plain or journal bearings contact is generally area contact. Hence friction is reduced in rolling bearing as compared to a plain bearings.
