  Material Use: 

Delrin is a Acetal AF blend, supplied as a 2:1 blend of Acetal AF-100 and Acetal 150 resins, has excellent sliding/friction properties. Bearings made of Acetal AF blend can operate at higher speeds while exhibiting reduced wear. These bearings are also essentially free of slip-stick behavior because the static and dynamic coefficients of friction are closer than with most plastics. Acetal AF blend retains 90% of the strength that is inherent in unmodified Acetal. 

303 Stainless Steel is very similar in properties to that of 304 Stainless Steel, However 303 has an addition of sulfur for better machining characteristics. 303 Stainless Steel is Corrosion resistant to temperatures of 1500 Degrees or more. It is used in screw machines, food processing equipment, marine applications, and some aerospace application.
