Another good high temperature grease is Super Lube. You can often find it at local hardware stores or order online from Amazon. If buying locally make sure it says PTFE on the label.

Super Lube 92003 Silicone Lubricating Grease with PTFE, 3 oz Tube, Translucent White: Amazon.com: Industrial & Scientific

Thanks for that. Excellent advice. Will try to source this as well.

It's really difficult to get alot of items locally (South Africa). I did do some looking online and found a grease which is for copiers and printers. Contacted the suppliers about 2 months ago and I'm still waiting for them to deliver. In the meantime I've been using car grease... Which I know is not the right stuff but I don't have a choice right now.. That's why I asked everyone for advice

look, I don't know, in over 32 years of work, I have tested hundreds of types of grease, of all type of compound, for that type of application, and they all really shit, that is, you went there for one other thing, and you noticed that the grease was not needed practically nothing, what I am trying, (which is an anti-friction for brake pads) seems to do its job for now ... I just ask it to last at least one pm cycle of the fuser...

as soon as I happen to replace a kit that used that type of "grease" (because maybe it isn't) ... I'll post photos with the final results for the replacement.....(cazzo!..1500 degrees of resistence vs 169 of media in work) im very curious!

From what I have researched today Spanjaard VHT White high temperature grease as shown is used mostly in the food industry to lubricate transport systems in baking ovens.

honestly speaking... it struck me too, that characteristic, I know those types of grease.. for the layman: they are used in machinery for the production of food products, so even if never, and I say never! should it happen that the food product came into contact with the product, a poisoning does not happen) all this does not make me think very positive in the field fuser unit!... in the sense that: it is like putting oil to fry chips, instead of engine oil, just because both are "oils"

Here are some ideas.

I always use a razor blade and lightly score the ends of the hot roller and grease the ends too. The bearings go on tight and never get noise for the life of the fuser.

If you ever get hear what sounds like a coffee percolator, it is the bearing that has run dry. If you don't have a new set you can pack them with high temp grease of silicon heat sink compound.

Hi all

Years ago with the MP2352 series, when the guys were in a corner with noisy hot roller bearings, they would cut a strip of paper as wide as the bearing and then flip the bearing and reinstall it over the paper.

It worked like a charm.

I agree that when the bearings had run dry, short of repacking the grease or replacing the bearing that was not much else one could do.
I remember repacking those bearings once with wheel bearing grease, which seemed to work ok.
