Telescoping Delrin® Acetal Round Tubes

Telescoping tubes, also known as bushing stock, slide over rods and inside shafts to increase or decrease the diameter. Their precise sizing also allows ascending sizes to fit inside each other to increase the wall thickness.

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.
