Should air cylinders be lubricated?

Air lubricators have been an important part of pneumatic systems for decades. Lubrication helps reduce friction between sliding surfaces to not only improve efficiency and increase cycling speed of a component, but reduces wear, which ultimately means longer component life and less maintenance.

Can you use oil in an air cylinder?

There are still a few pneumatic products that require internal oil lubrication. Anyone who uses a pneumatic tool understands that light machine oil must be added periodically. Additionally, some air motors and air clutches also require internal oil lubrication.

Do I need an oiler for air tools?

You do not need an oiler since many of the newer tools are oilless. For those that do require oil a couple drops of Marvel Air Tool Oil into the tool before use will do the trick.

Do I need a compressed air lubricator?

A rule of thumb states that every 2-psig increase in operating pressure adds 1% to compression energy cost. Point-of-use FRLs (filter, regulator, and lubricators) are needed to ensure that every tool or process receives a clean, lubricated supply of compressed air at the proper pressure to provide peak performance.

What to spray in cylinders before starting?

The manufacturer recommends a six-step process:

  • Start the engine and remove the air filter.
  • While the engine is running, spray STA-BIL fogging oil into the air intake of each cylinder.
  • After 10 seconds, shut off the engine.
  • Remove the spark plugs – carefully!

Why lubrication is needed in pneumatic systems?

Why is this? Early pneumatic products like valves and cylinders used natural rubber and other materials for seals. In fact, leather was often used for cylinder rod seals. Have you ever heard the term “packing?” These materials required oil lubrication in order to seal effectively and reduce friction.

Why would a lubricator be used in a pneumatic system?

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. A lubricator should always be the last element in an FRL (Filter-Regulator-Lubricator) unit.

What kind of oil do you use for an air lubricator?

Use only clean oil, SAE 10 or lighter is best.

What makes a good air cylinder lubricant?

High-pressure tolerance helps the grease stay where you put it and prevent any metal-on-metal contact within the cylinder. Long-term mechanical stability. Lubricants with high mechanical stability resist changes in viscosity and lubricity over time, which helps air cylinders perform consistently with each and every stroke.

What are the requirements for pneumatic cylinder lubricants?

These requirements include: High pressure tolerance. Internal air pressures in pneumatic cylinders, which routinely reach 250 psi, can cause the lubricant to separate and migrate. High-pressure tolerance helps the grease stay where you put it and prevent any metal-on-metal contact within the cylinder. Long-term mechanical stability.

Why is compressed air used as a lubricant in hydraulic engines?

The compressed air can suspend a limited amount of oil smoke which helps self-limit the lubricant (maximum lubricity). Turbulence in a small manifold causes wet out, replenishment and flooding. Boundary layer turbulence will wet out a small amount of oil even at low velocity.

How can I improve the performance of my compressed air cylinder?

Improving air filtration is another option to enhance cylinder performance. Water: Water vapor is present in all compressed air applications, where it collects within components to block orifice flowthrough, dilute pre-lubrication grease, adulterate airline lubricants, damage barrel or rod finish and freeze in cold weather.
