Pneumatic air cyl lube
Pneumatic air cyl lube
(OP)
Hello,
Was wondering if anyone has ran across a good spray lubricant/grease that could be sprayed in the pneumatic lines to coat the cyl./ valve seals. What happened was some one put oil in some air lines and flushed out the factory lube. Took the valves ans cylinders apart, every thing looked ok. Re lubed all the seals with a grease in house. Would like to find a good spray , if made to spray on each side of the cylinder if need be.
Thanks Nod

I don't doubt that some of the units get regular ole engine oil when they're in an outside shop...Mike

More concretely, syntetic lubricant will generally attack common seal rubber (NBR). If you can't find data about seal material, use of mineral oil will avoid risk in most of usual conditions.
I am not sure about spray. For pneumatic lines you can use oil either specified as "air line" or "circulation/general purpuse" oil, depending on maker. Viscosity grade should be ISO VG 32 for medium duty in-plant installation; for lighter duty you can use VG 10 or VG 15 (that should be suficciant for most purposes: we use VG 10 for mould locking cylinders on high-speed bottle blowing machines, recommended by manufacturer of the machine).
Back to spray matter, manufacturers often offer chain spray, but it has VG 150 and is not appropriate choice for this (except for initial seal installation). The same with grease in spray. Mist lubricator installed in supply line using mentioned oils should be "normal" solution for lubrication during operation.

I am pretty sure that lube you noticed is simply remained after assembly and is not intended to be solution for permanent run. Manufacturers (which is yours?) clearly specify is the cilinder adequate for dry run or not. If it is (most standard ones from Bosch or Festo are) you don't have to care about it. If it isn't, you have to introduce oil because grease is simply not the solution for pneumatic equipment (of course maybe that is something new I don't know about, but I din't notice it in any available edition of documentation or literature. It is only a common recommended practice to lighly grease the seal during installation, but you have to take care of grease type and seal material as mentioned in previous post.)
Good luck!
