On topic. Anti seize on outside of bearings

I know I could post this in the combine section, but it is a general question. I have an Oliver 7300 combine. There is a bearing on the end of the crankshaft. it is outside the block on the opposite end from the fan. On a regular application it would be where the flywheel would bolt up. It has two pulleys on it. One is for the main drive belt. The second one is for the belt that drives the threashing cylinder. Beyond the pulleys is the bearing I have a question about. This bearing fits on the end of the crankshaft. The outside of this bearing fits into a castiron support housing. If you need to change a belt you have to remove this housing....thus needing to either remove this bearing from the crankshaft or from the housing.

Now after all this information here is my question......Can I put some antiseize on the outside of the bearing to make removal easier? Will it cause the bearing to turn in the housing? Are there any reasons I should not use it?
 
assuming it's a ball bearing - I'd say you're fine putting antiseize on it.

If things get so bad that it'd want to spin, you've got some major trouble anyways.
 
I would rather use some teflon tread sealer on the brng and in the bore to seal both edges of the bearing in the bore so it'll keep the rust out, it is sticky and will last longer than antiseize. The antiseize will just scrape off with a press fit.
 
if it's a press fit the anti-seize will will be wiped off when you press it in, so no matter what you put on it will be a waste
 
A little on the outside should be OK, but be careful not to get any in the bearing, it's not recommended. Anti-seize has metal particles in it. With a belt drive there should be enough side load to reduce the possibility of the outer race turning.
 
I don"t believe the "wipes off since it"s a press fit" comments........it sure doesn"t wipe off my hands if even a little bit gets on.....LOL
