Hi there!
I use maintenance-free spherical bearings for an aplication of very high loads (300mm diameter spherical bearings or larger are used) in a very dust laden environment (mining industry). I could, to avoid dust in the spherical bearing, protect is with grease and assembly it in an enclosure.
But in the manufacturer's catalogue it's written: "PTFE fabric spherical bearings must not be lubricated" and I'd like to know why.I wonder if it means that there is no need to lubricate or if the PTFE will be damaged? Does anybody has experience with this issue? Can contact with grease ruin the this kind of beaaring?
Regards,
Pedro
