what are the example sof antifriction 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.
in friction type the bearing metal is direct contact with shaft metal, but in the antifiction the rolling element is contact with the bearing races only.
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..
the difference between frriction bearing and antifriction bearing kya jan ke karega maal pata dateing ja or as kar......... bye...........
