anti-friction bearing
A plain bearing typically consists of a simple design where the shaft directly contacts the bearing surface, such as a sleeve or journal bearing. An anti-friction bearing, on the other hand, uses rolling elements (like balls or rollers) to reduce friction between the shaft and the bearing surface, allowing for smoother operation and potentially longer lifespan.
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.
Friction bearings rely on direct contact between surfaces, such as metal on metal, to support loads, while antifriction bearings use rolling elements (balls, rollers) to reduce friction and support loads more efficiently. Antifriction bearings are typically smoother, have lower friction, and require less maintenance compared to friction bearings.
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.
there are many types of bearings .... 1)ball bearing 2)roller bearing 3)ball thrust bearing 4)roller thrust bearing & 5)tapered roller thrust..
