Will these last me a life time?

The bearing return area of my company is sending me 200 bearing rollers. Ther is a picture of the five different styles that they are sending me. All of them are 52100. Most of them are 1" cylindrical rollers like the one on the far right in the picture of rollers only.

The entire bearing (rollers and races) in the other two photos is 52100. They're sending that also. Since I'm a spare time maker, these will last a very long time.

:) :eek: :cool: :p :thumbup: ;) :D :o

I know you're totally used to big bearings like that, but if I got my hands on one of those big boys with rollers and races intact I don't think I could dismantle it. Too cool; I'd have to build a stand for it. LOL

Very nice of your company! :thumbup:
 
Nice score Scott! So, I'm guessing you'll be specializing in 52100 with your knife making huh? :)

This is the first one of those Ive seen before. Ive had the rollers from them but have never actually saw the whole bearing assy. Very cool.
 
I work at the largest craft paper manufacturing facility in North America.... read EVERYTHING is BIG.

Right after I started they "threw away" about 350 BRAND SPANKING NEW bearing/races that were all in the 12"-45" diameter range. They were all still in the crates with wax paper and grease in tact.

One of the bigger ones was comprised of several dozen roller bearings that were about 2.5" in diameter and 5" long.

All from Timken. One of the vendors from Applied Industrial Tech told me it was something like a $50,000 bearing.

Of course they won't let me take any of it.... it's all got to be recycled :grumpy:
 
Some years back I watched the bearing races being made (forged). I too have a few of them and also some of the large bars of the steel they start with. It would be kind of interesting to see (keep track of) how many inches of bade steel could come out of one race. I suppose it could be caculated but that makes me tired just thinking about figuring it.

i had a couple of the inner and outer races about that size... off of some kind of longhole drill... .. it was a bear to hot cut and forge out... but made some nice knives...

good scoop

Have you tried telling them you'll pay what the scrapper pays them per pound? Alternately, when the scrap dealer comes to pick them up, have you talked to him? You might be able to get some off the back of the truck.

I would have thought that after a year as a yard monkey you'd now consider "recycled" to mean you putting it to any new use other than originally intended, corporate or personal. :D

I have a stand for it! I can dismantle the entire bearing in about half an hour. The cage is solid brass too. I now have 6 of those large rings and three large brass cages. I'm not sure what I'm going to do with all of the brass. I'm wondering if I can forge it. If I can forge it, I'll have to learn whether I can forge it cold or do I have to heat it up to a certain temperature. Lots to learn!

Nick,
Since you work there, you're technically one of my customers. I also like to share. The next time I'm in your area, I'll stop by and drop off a bunch of rollers. If you want a large race, I'll bring you one of those for you too. Message me with your contact information and we'll hook up the next time I'm in your area.

Scott, what's the retainer made from ? Is it salvageble ?

Solid, machined brass. As stated earlier, I need to learn how to work it. I'm sure I can forge it. My biggest worry is screwing up my forge. I made mokume in my forge once and it really screwed me up on my next damascus billet.

Bruce,
If you want some rollers or a race, I'll drop them off the next time I'm in your area.
 
That's great!! Many happy hours ahead! ;) My brother-in-law is a D.O.T. mechanic and saves me all the BIG bearing races from the state trucks. Just cut and straightened the first one the other day. Nothing like free steel!!:D
 
SKOTTICKES: If I counted correctly the complete barring in the photo on the right has 50 bearings. If you are getting 200 bearing assemblies and they all have 50 bearings in them then:

If you made 1 knife a week from just the bearings(not including other parts of the assembly) you have enough material to make knives for at least the next 192.3 YEARS !!!!

Tell me what the part numbers are. I'm 99% sure that those are low carbon case carburized steel that will not work in a knife. The inner core is only .2% carbon. Only the thin outer layer of the steel is 1% carbon. The process of heating and forging will decarb that outer layer, leaving you with basically a really good angle iron steel!
