High Temperature Pulleys
Harsh Environment Pulleys



For use up to 500oC

Recommended for corrosive aqueous baths and molten metallic baths, these pulleys withstand temperatures up to 500oC, free of molten metal adhesion. The Alumina shaft offers a 65% strength of an equivalent 304 stainless steel shaft at 500oC. The maximum operational speed is 1,000 RPM. See the first image below for details of construction.  The dimensions of the available pulleys follow. Web safe color has been chosen for illustration purpose. We may deliver the pulleys in a different color.
