Bearing lubrication question

[Bruceter]

Hi all,

I am working on an older Delta Homecrafter drill press that my Dad gave me.
When it was turned on, there was quite the howl coming from the headstock.
I found instructions and an exploded diagram for it and have gotten it apart and the offending bearing out. It is obviously a special made bearing for this drill press as the inner sleve extends out the bottom of the bearing. (It looks like a top hat from the side.) It was very "crunchy" when rotated. I blasted it out with penentrating oil and it is better now.

The question is, what should I lubricate it with. I would like to be able to use it while I look for a replacement bearing. I have several choices from a spray dry film teflon lube to a florinated oil.

TIA.

You don't want to use spray dry film Teflon. And it doesn't require anything fancy. Regular old lithium grease will work fine as would electric motor bearing grease. These are not expensive, but they are a correct lubricant. If you clean the bearing and repack it (about 20% full of grease, not actually completely packed) it will likely be just fine.

I looked at it and it doesn't look like I can get the shields off of the sides of the bearings to pack it with grease. I'll dig out my camera and post a couple of pics.

Here is the drill press I'm working on.

Here is an end view of the bearing.

Side view.

The bearing sitting on a 1-2-3 block for some scale.

The inner sleve with the tapped hole is part of the bearing. I don't thing it's going to be easy to find a replacement for this at all.

you may try here. http://www.ereplacementparts.com/ you will need a model number from the drill press. If you can't find it there, you may try a place that specializes in industrial bearings, we have a store here in central Mo. that has or can get about any bearing ever made. It is Indutrial Bearing and Transmission, it may have other locations, not sure.

Are you sure the inner sleeve is not just pressed into the bearing? Looking at the pic it looks like it could be a pressed fit into the bearing itself!

This press looks like a Walker Turner to me. They used to make the pre-Craftsman machine tools for Sears & Roebucks and I believe (although not 100% certain) that they also made machines under other names too.

If you want to really look into what you have you can start searching here...

There's some info on people who can supply parts to these old machines too, you just have to dig for it.

since your spray oil worked it's way into the bearing , here is my red neck idea . Get some auto synthetic oil , mix in some dry moly and soak the bearing in it for a day . If you cannot find dry moly , get some hi temp wheel bearing grease , it has moly and graphite in it and make up a thin mixture . I have used this before , I am not making this up . Worked great on guns .

The parts breakdown I have shows it as a one piece bearing. I am certain that it is not pressed in.

It is a Delta homecrafter, I should have taken a pic of the name plate. I looked at that site along with several others. I have found placed that used to have the bearing but it is now discontinued.
If I can't get this bearing to work, I'm going to get a plain bearing and machine a sleve to press into it. This bearing gets assembled into the upper pully, the tapped hole is what holds the assembly into the casting.

Thanks for the links and the idea's.
