TPT pneumatic actuators are factory-lubricated for life to ensure a trouble-free service life and 1,000,000 cycles may be expected. However, this applies under ideal conditions. Under real conditions, the service life depends on several factors.
Contaminated air from air compressors and air supply system is the most common cause for shortened life service (solids, water, and oil). This contamination will gradually degrade and wash out the original grease lubricant. This will shorten the service life, therefore it will be almost impossible to accurately predict the service life.
If the compressed air supply is clean, dry and filtered to 40 micron, the grease will give the seals and components long life without adding oil through an oil mist lubricator.
The oil mist lubrication will extend the life of the actuator, but it will also wash out the original lubrication. Once begun, the oil mist lubrication cannot be discontinued and the lubricator should be regularly checked and maintained. If air lubricators are used, the lubricant selected must be compatible with Nitrile (Buna-N) seals.
Sealed and Unsealed Actuators
Our sealed actuators are maintenance free and our unsealed actuators are available for preventive/corrective maintenance. Life service of a pneumatic actuator is significantly extended only with a grease re-lubrication and replacement the O-ring seals.
How do I choose the right actuator for my application?
It depends on the number of operation cycles. For example, some actuators may perform hundreds of cycles per hour, whereas others open and close just once a day.
Please take a look at the chart below to make a decision.
|Cycles rate||Cycles per hour||Actuator recommended|
|Low||1 to 5||Sealed|
|Medium||6 to 19||Sealed / Unsealed|
|High||20 to 30||Unsealed|
