Problem with bearings on a drum roaster
Nilewoods Roaster
Hi -
My Kaldi Wide roaster has two bearings in the front, which support the front flange of the rotating drum.
Though I've oiled the bearings, and brushed chaff off them, I find now that they won't turn freely.
Taking them apart, I can dig out what looks like burned on film and gunk; now they're soaking in vinegar to see if that will help, but it's a stubborn varnish-like coating that you might see in a carburetor.
The individual ball bearings are in a plastic race and thus stay put between steel rings, and the face plates come off, which makes cleaning a bit easier, but also admits chaff which gunks it up over time.
Is there a way to solve this problem? An easier way to clean them? Or, replace with sealed bearings? Need replacements be adapted for high temps?
Thanks for any suggestions.

Here's what I came up with.
First, disassemble the bearings.
Second, soak them in vinegar overnight.
Third, use a sharp pin to pick out all the varnish. This takes some time, to get back to bright shiny metal.
Wash off (scrub with toothbrush), let dry fully.
Reassemble the bearings.
Lubricate with Tri-Flow.
Exercise the bearings some.
Reinstall them on the roaster.

That has worked here. And after several roasts, the Tri-Flow is not picking up or holding onto as much chaff debris as the avocado oil used to. The bearings are still shiny and turning easily.

Is Tri-Flow a certified food grade lube?

I'm not sure, but I am looking at building a roaster myself someday in the distant future and am copying everything of interest... I snagged this in relation to front bearing lubrication:

(For front bearing) Steve recommends high temperature grease, preferably without lithium. Products he recommended include Red & Tacky, and Jet Lube AP-1.


Others feel free to chime in though.
