I have recently fetched an old 9 inch circular magnetic chuck from storage. It's for disposal as I no longer have a large enough lathe and I can barely lift it anyway these days! It needed freeing up as the internal lubricant had hardened. After treatment with PlusGas and flushing with white spirit I need to re-lubricate. Does anyone have any suggestions for the correct oil and the quantity used – I assume it's not designed to be filled up because of balance problems.

We just used 60 grade slideway oil but dont dismantle or you will loose the magnetism and it will need re-magnetising.

I have one somewhere, it gets whatever is in the oilcan when I remember to oil it which is usually when it starts to get stiff.

Many thanks for the comments. It's now had a squirt or two of SAE 30 and seems to be fine – still a good powerful hold. I did find a suggestion on the web that the flux may improve if stored face down to keep the magnets in close contact with the pole pieces, but that may be fake news. Now to find out what its resale value is!
