'Sup /diy/nosaurs?
Im in the process of replacing the spindle and quill bearings to pic related
the chingchong quality bearings lasted about 20 hours of very light use (over about 14 months since I got it) and now they sound like a cement mixer, yeah thats whats to be expected for the chinese shit but still, I paid 1450 euros for this thing and I still plan on using it.
the seller is a bit reluctant to help me with this as they would have sold me the same god-dam chinchong bearings for a ton of money so no deal there.
I've already pulled the bearings and ordered new high quality SKF bearings for it
the question I come to you with is what grease should I use on the quill angular roller bearings? the upper spindle bearings are enclosed and thus need no lubrication....
I was thinking about something like CRC molybden-suphide lithium grease but I dont really have too much experience with different greases
the thing does about 3000 RPM at max.
so any suggestions?

pic of the upper spindle bearing
the brand is "RIFU" wich sounds sketchy
but the installation just screams china quality
pic related, yes those are fucking hammer dents on the cover plate of the bearing

I have heard, but not confirmed, that moly is actually too low friction for bearings, as it causes them to slide, rather than roll.

An NLGI No. 2 grease, such as a wheel bearing grease or multi purpose lithium grease for your car. You don't need anything fancy as it's not exactly a heavily loaded application, nor do you need it to be waterproof. Typically it is a light amber colour.

Go to an automotive store and pick up some White Lithium Grease. It'll be fine for this application.

Check the bearing seats and alignment. Even chinese bearings should stand up to a decade of normal use in a milling machine. Also check the head casting for casting sand.

Ben je verder tevreden met de machine? Ik overweeg de zelfde te kopen.
