Hi
What I am doing is fixing a hot melt glue applicator in a edge bander for a friend.The glue applicator ceased due to lack of lubrication. I would say it's never been lubricated since new, approximately 30 years ago
The shaft comes through the bottom of the glue pot and delivers the glue to the board edge.
There is a cone seal at the top of the bearing housing of metal to metal...see photos. The large diameter of the cone is in contact with the hot glue, and the other half that does not rotate is spring loaded.
It looks to have an oil hole with a ball in it. I have not been able to open it yet.
This whole thing runs hot at around 200c at about 100 rpm and it has no load on it.
I will put new bearings (6005z) in it. The old ones had the seal removed on the inner side of the bearing. The spec on a 6005 is 100c so I guess they removed the standard lube and let the oil that was put in the top drip down???
My question is what lube to use
A; oil or grease?
B; would a heavy engine oil do?
C; should there be a packer in here?
Note.. there was no glue inside the bearing housing... none had got passed the cone seal.
Thank for your advice here
