Pulley Surface Finishes

MaterialCharacteristics
Aluminum-suitable for moderate power transmission -light weight / reduced rotational inertia -moderate chemical and corrosion resistance -standard material for stock pulleys
Steel- suitable for high power transmission - durable - limited chemical and corrosion resistance - aesthetic material
Stainless Steel- suitable for high power transmission - durable - meets FDA regulations - excellent chemical and corrosion resistance - aesthetic material
Delrin- light weight - excellent chemical and corrosion resistance - non-metallic - stainless steel screwed on flanges or self-tracking recommended
