I am in need of flange or pillowblock type bearings, for a 7/8in shaft, that are capable of withstanding 6000-8000 rpms. I have been searching for spec's for the popular surpluscenter, tractor supply, northerntool varities and can seem to find a speed rating to go with the bearings they sell. I think the standard bearing is only rated to about 3500rpms, but havent been able to verify that. The shaft will be supported by 2 bearings on either end and wont be over approx 16inches in lenght. There will be a double V pully of 2.55inch dia on one end and a 13tooth .404 saw chain sprocket on the other end. I will be applying approx 20-25hp of hydraulic power to spin the shaft. I need to know if there is a specialty bearing I can buy that will meet my requirements, as well as where I might purchase it. Any help would be appreciated.
