I believe they will still make them... but it would be a special order and there will likely be a minimum order quantity to purchase them. It would be nice to order them with the correct ID so that they don't have to be reamed/honed out to fit the shaft after pressing them in the gear but I have no idea how many thousandths of material I am removing when I do that (I don't have the proper tools to measure that).

Anything sintered doesn't have the same load capacity as solid-cast. I am pretty sure a standard SAE660 cast bronze bushing would have a higher load tolerance than the ones you posted.I wonder how these would hold up.

You would have to turn them down to size
I have 8 of the SAE660 cast bronze bushings that I could sell... if you are looking for bushings. I bought a group of them before I found out about the ToughMet3 material. I ended up buying the ToughMet3 and the SAE660 cast bronze bushings got shelved.

OK. I looked up my research that I had from when I was looking for bushings.
The sintered iron/copper bushing that was posted has a max Pv of 75,000 but that is a 1-1/2" long bushing and the spec is for use of that whole length. You would need to cut down the length to 7/8"-1" long which would reduce that value.
The Bunting SAE660 cast bronze bushing #CB161808 also has a max Pv of 75,000
The Bunting Eco Bronze bushing #EBCB161808 has a max Pv of 100,000
The Bunting ToughMet3 bushing #TMCB161808 that @SPM and I are running has a max Pv value of 275,000
Typical Pv value for the stock, teflon-coated type of bushing is around 40,000-50,000 but it seems like it should be lower since the teflon coating gets "pushed" off the bronze layer underneath.
I believe that "Pv" is a number that is related to the maximum pressure (load) at the maximum velocity, but I would have to look that up in more detail to be certain.
