If these are replacing rubber bushings I don't see the need to heat

These bushing assemblies attach the front of the swingarm (rear fork , to
some) to the pivot shaft . This shaft attaches to the frame , and also
supports the rear of the engine/transmission assembly . This is an 800 pound
touring motorcycle ... and those composite bushing assemblies are quite a
bit more complicated than a "rubber bushing" .

What you're making is similar to these, no? http://tinyurl.com/2el9xx
Those are delrin with high carbon steel sleeves. I didn't ask if
they're heat treated, but I suspect so.

Actually, I just pinged Kevin there and will letcha know.
