Hey guys, I got a monster wheel bearing from a triple 7 caterpillar dump truck. I'm trying to find any material or manufacturers mark (been in class all day), but haven't found one. Any ideas as what it might be made of or disassembly? I might just wait until I build a bonfire and anneal it there, and then take a die grinder and cutting wheels to it unless any other advice is offered.

Wheel bearing, won't fit my Malibu or Camaro. :)

Email/call CAT and ask. Ballpark guess is it is 52100 for the bearings though.

I wouldn't anneal it unless you are going to make something from it. I would remove the cage and rollers and use the rest as a dishing form for now. 

I had a good idea, results will be posted in the future to determine if it is a good idea or just an idea.
