Hi,
I am restoring an old lapidary saw. It has two bearings on the arbor shaft and I know that one of them needs to be replaced, the other one is fine.
I am looking for help with 2 things:
1) I haven't done this before and I am having trouble getting the bearing to come of the shaft. It has eccentric locking collar and I removed the set screw already. I tried inserting a screw driver into the other hole and tapping it in the other way than the way the shaft usually rotates in. It doesn't budge. Any tips on how to get it off or maybe even links to some good videos explaining how to get a bearing like that of the shaft?
2) I am trying to figure out what bearing to replace it with. The collar has this on it "204-012 SKF MADE IN USA". I was able to find these on ebay but the pictures look a bit different and there are several sub types. Do the bearings need to be exactly the same or what are the important parameters to look at?
This is a picture of the bearings and the shaft.
Thank you, I am very new to this!
Tereza.
