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.

Friction can be reduced by changing over from sliding to rolling or rolling to sliding?
rolling to sliding
What is rolling friction and what does it do?
In general rolling friction is any friction specifically related to the rolling motion. The friction on the axle to hub bearing, the tire flexing, the tire tread on the surface of the road and so on.
What is the difference between friction and antifriction bearing?
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.
Friction can be reduced by changing over from sliding to rolling or rolling to sliding or Potential to Kinetic energy or dynamic to state?
sliding to rolling
The size of forces due to static sliding and rolling friction between two surfaces?
static sliding has a much greater force then rolling friction cause it covers more area
How is rolling friction caused?

Is it true that rolling friction always reduces the net force acting aginstan objects's motion to zero?
Friction can be reduced, but in most cases there is no practical way to reduce friction to zero.
Which friction has least value option sliding friction static friction rolling friction Air friction?
i think it it rolling friction
Is the limiting friction is always less then rolling friction?
no limiting friction is not less than rolling friction
What are the three types of friction and when does each apply?
There are three types of friction, static friction, rolling friction, and sliding friction. Static friction is friction between two surfaces that aren't moving relatively to each other. Rolling friction is friction between a rolling object and the surface that it is rolling on. Sliding friction is friction where an object slides, or rubs against, another surface.
Why does a ice-hockey puck have less friction than a ball rolling on the ground?
Ice has a much smoother surface than the surface of the ground, therefore there is less friction acting on the hockey puck compared to a ball rolling on the ground. Ice is nearly a frictionless surface.
What is the Direction of friction for a rolling body?
The direction of friction of a rolling body is in opposite direction to the motion of the rolling body.
