A lubricant such as oil and ball bearings are just (2) methods of reducing friction.
Lubrication, is one way.Two ways to reduce friction are :.Lose weight.Wet the surface
If I'm not mistaken, there is no machine that can reduce friction. The machine is intended to change the distance the input force is applied over or to multiply the output force. The moving parts of the machine will always increase friction. In order to reduce the extra friction (but not completely remove it), one would use a lubricant or reduce the roughness between two surfaces. Hope it helps.
Reduce contacting surface area between the two objects, and to use lubrication.
Thank you
way1.we can put oil (a lubricant) to reduce friction . a lubricant has a property that reduces friction .it has a slip that can easily move parts of machine without a irritating voice. before applying a lubricant it may may make a noise but after applying lubricant it stops making noise. way2.by putting wheels under a big box or any big thing we can reduce friction because rolling friction is less . on wheels any thing can move easily .we have to not apply more force to move it ,with less force also it will move easily.

The oil helps slick the two surfaces so that the molecular surfaces become easier to slide on with less friction. Julia Blander :P
Polish the interacting surfaces or decrease the normal force acting on the moving object.
Friction force oppose motion between two bodies that are in contact. This force is important in machines and pulley systems in that it enables the gears to have grip and there is no unnecessary sliding.
Lubrication and ball bearings both reduce friction.

Okay 2 ways for the friction to increase is speed and non lubricant
How does the flow of air reduce friction of the hovercraft in motion?
There are two most widely used methods to reduce friction__Using lubricants.Converting Sliding Friction into Rolling Friction
