Here in this question neither of them are correct. As the friction bearings are not made of balls and rollers. Also, non friction bearings are not in a sliding contact between moving surfaces.
In order to provide a low-friction support surface for rotating or sliding surfaces, friction bearings are composed of a stationary, non-moving bearing surface, such as machined metal or a pressed-in bushing.
Lubricating oil is frequently used in friction bearings to isolate the moving part from the mated non-moving bearing surface. An antifriction bearing uses rolling parts connected by inner and outer rings to absorb the radial forces acting on the rotor.
It is typically mounted to the shaft with an interference fit. Pumps and aero-derived gas turbines frequently use antifriction-type bearings.
