A lubricant such as oil and ball bearings are just (2) methods of reducing friction.
Two ways to reduce friction are to use lubricants, such as oil or grease, to create a smooth surface between moving parts. Another way is to use ball bearings or rollers to minimize the surface area in contact and reduce friction.
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.
While a well-oiled machine may experience reduced friction compared to a dry one, it will still have some level of friction. Friction is inherent when two surfaces come in contact, even with lubrication. The goal of lubricating a machine is to minimize this friction and reduce wear on the moving parts.
You can reduce friction by using lubrication, like grease for bearing, sewing machine oil etc.
Lubrication: Applying lubricants such as oil or grease between moving parts can help reduce friction by providing a slippery layer that allows parts to glide past each other more easily. Using ball bearings or roller bearings: These components help distribute the load and reduce the contact area between moving parts, decreasing friction and wear.

All machines that have moving parts are affected by friction. Friction occurs when two surfaces rub against each other, which can cause wear and tear on the machine's components over time. In some cases, friction can reduce the efficiency of a machine by converting some of the energy into heat.
The oil helps slick the two surfaces so that the molecular surfaces become easier to slide on with less friction. Julia Blander :P
You can increase friction by increasing the roughness of a surface or by increasing the force pushing the surfaces together. You can decrease friction by using lubricants or reducing the contact area between the surfaces.
Professional bicycle riders reduce friction by using high-quality lubricants on their chain and ensuring that their bike components are properly aligned to reduce unnecessary friction. They also frequently clean and maintain their bikes to ensure optimal performance.
Polish the interacting surfaces or decrease the normal force acting on the moving object.
In machine components, such as bearings or gears, excessive friction can lead to wear and reduce efficiency. In sports, like ice skating or skiing, minimizing friction is desired to allow for smooth and fast movement.
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.
