to reduce friction and make the object move smoother.

it opens faster and easier
Some advantages of using plastic bearings are that it saves money, it has corrosion and chemical resistance, designed to maintain a low COF, no messy lubrication and resistance to dirt.

It is heavy and might damage bearings
Precision bearings, on the other hand, are highly accurate in terms of material quality, consistency of finish and diameter, and repeatability of tolerance levels.
Yes, in the seals around the bearings, in any suspension element you might have, by the brake pads and so on.
J. P. Reinhoudt has written: 'On the stability of rotor-and-bearing systems and on the calculation of sliding bearings'
Generally, journal bearings have higher friction factor, consume higher energy and release more heat, but they have larger contact surface, so normally used in low speed high load applications.
Rolling friction is less than sliding friction so it is easier to move heavier objects using wheels.
The main advantage of installing sliding doors in a closet is that they take up a lot less space than the traditional door. They are also quieter to close, and do not require cumbersome handles or hinges.
