Thread: Hercus Oil

You could also use a 46or68 grade hydraulic oil.

I don't know about the absorbing water description, but a plausible reason I heard why engine oil isn't best for machinery is because it has detergent in it. This is good for engines with filters, as the particle contaminants get carried with the oil and caught by the filter. Machinery with no such filter just get the contaminants spread wherever the oil goes. It's better to let the rubbish fall out and collect at the bottoms of the various crevices.
It can be cleaned out occasionally, or when the machine is overhauled.

He stated that the correct oil an ISE 100 Bearing and Circulating Oil.

(I intend to use Air Compressor Oil as it appears to have the correct spec and can be purchased in a smaller quantity than 20 litres.)

I just recieved some Hercus 9 oil recommendation charts along with a batch of brass plates for the 260's. I will attach a picture you can download.
