Ultra-Low-Friction Delrin® Acetal Rods

While just as dimensionally stable and machinable as standard Delrin® acetal resin rods and discs, these have a PTFE filler to make them more slippery and wear resistant. Fabricate them into pump components, gears, and bearings. Delrin® acetal resin is also known as acetal homopolymer.

Ultra-Machinable Delrin® Acetal Round Tubes

Easy to machine to close tolerances, these dimensionally stable tubes resist expanding when exposed to heat and moisture. They have a naturally slippery surface along with excellent wear resistance. Use them to make precision gears, bushings, and bearings. Delrin® acetal resin, also known as acetal homopolymer, is stronger and stiffer than acetal copolymer.

Oversized Tolerance—Oversized tubes have an oversized OD and an undersized ID for finishing to the sizes listed.
