What kind of temperatures do the small wheels end up tolerating? I know that you should run them slow enough that you can touch the bearings comfortably. I would think that the axle serves as a heat sink and was wondering what the guesses are for the temp of the axle and rubber interface.

Thanks for the help.
 
Keep the speed as low as the work allows. They will come apart if run to fast. The rubber itself distorts and goes out of round causing this to happen. I don't have pictures but trust me.
 
I am inquiring because I want to screw around with an idea and based on that wanted to hear some best guesses as to temps. I am not asking how slow or how fast to run these as I already repeated the often stated recommendation to ensure that the bearings are not too hot to touch. Fred, it's always a good recommendation to run the belt as slow to get the job done. Thanks
 
Tubber or Poly ?


the tech service at the contact wheel makers like sunray know what temps you can go to


Tracy Mickley mentioned it in some advertising for poly wheels.
 
300 degrees for poly. I run mine at 20 on my vfd with 6" drive wheel on my tw-90 and they cut a2 at 61 like its soft. Such a small wheel definitely cuts easier. No need to ever crank up the speed personally.
 
Rtv silicone silicone is the ticket it seems. This was recommended by a guy that sells the product.

Seems they have lots of high temp limits. I don't think for this application that 600f is needed.

Thanks for the comments.
