Motor oil, a common lubricant. A lubricant (sometimes shortened to lube) is a substance that helps to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. It may also have the function of transmitting forces, transporting foreign particles, or heating or cooling the surfaces.
A sliding glass door. In architecture and construction, a sliding glass door (also patio door or doorwall [1] [2]) is a type of sliding door made predominantly from glass, that is situated in an external wall to provide egress and light.
PTFE is a very soft material, thus its friction coefficient becomes worse than that of hardened steel-to-steel mating surfaces under common loads. PTFE is used in composition of sliding bearings where it improves lubrication under relatively light load until the oil pressure builds up to full hydrodynamic lubricating conditions.

Tribology is the science and engineering of understanding friction, lubrication and wear phenomena for interacting surfaces in relative motion.It is highly interdisciplinary, drawing on many academic fields, including physics, chemistry, materials science, mathematics, biology and engineering. [1]
A pneumatic lubricator injects an aerosolized stream of oil into an air line to provide lubrication to the internal working parts of pneumatic tools, and to other devices such as actuating cylinders, valves, and motors. Compressed air enters the inlet port and passes over a needle valve orifice attached to a pick-up tube.
Acoustic lubrication or sonic lubrication occurs when sound (measurable in a vacuum by placing a microphone on one element of the sliding system) permits vibration to introduce separation between the sliding faces. This could happen between two plates or between a series of particles.
As with standard roller chains, self-lubricating roller chains consist of five basic parts: inner plates, outer plates, pins, bushes, and rollers. However, the bushes for self-lubricating chains are sintered metal, produced using powder metallurgy. Self-lubricating chains can be manufactured cheaply, quickly, and to precision tolerances. [8]
A large area of glass can also be added between the sun room and the interior living quarters. Low-cost, high-volume-produced patio door safety glass is an inexpensive way to accomplish this goal. The doors used to enter a room should be opposite the sun room interior glass, so that a user can see outside immediately when entering most rooms.
