I'm not certain I understand this correctly, but are hydraulic presses used to forge billets of steel? I have a 12 ton press and would like to flatten 1 1/2" by 3/4" (approx.) roller bearings. I'm guessing the bearings would lose heat too fast and/or the press isn't powerful enough. Thanks.

If you know the manufacturer of the bearings and have a part number call them. They will tell you what the material is. Timkin tells me that "most large rollers are case hardened.
Spark test then try one and forge it to a half inch square rod. heat it to nonmagnetic and quench it if it snaps like a glass rod it "could be" 52100 or some other carbon steel.

Your 12 ton press, does it have dies?? How do you operate it hand pump ??
No dies, I'd have to come up with something. It's one of those orange, bottle jack, Harbor Freight or Northern Tool rigs. You pump the handle on the bottle jack. It didn't seem to me that it would work, but perhaps someone else has tried it.

I think you will need bigger bearings. Your blades will be small but I bet you can do it with 12 tons . Why dont you build a forging press? They have electric motors and develop about 26 tons. They make short work out of any forging project.
Since some weeks we have the possibility to use a 160 ton hydraulic press. A fast one, this is. Operates 4" in about 5 seconds. We have to preheat the dies to work hot steel with it. Tried to flatten 1 1/2" round bars of 52100 with it. It took us 2 seconds to press them down to 1/2". These big presses are dangerous, as you may destroy more than you produce. Still ideal for welding large damascus billets (more than 20 pounds). We will have a large rolling mill beside it, soon, to roll out such big billets.
