    Hollow Linear Shafts

    Image of Product. Front orientation. ZoomedIn view. Linear Shafts. Hollow Linear Shafts.
    Substantially lighter in weight than standard shafts, these are best for light loads. You can also run wiring, pneumatic tubing, coolants, and lubricants through the shaft's hollow center. Pair with linear bearings and shaft supports to create smooth, precise motion. These linear shafts are turned, ground, and polished to tight tolerances and hardened to resist wear.
    Steel—Stronger than aluminum and stainless steel. These shafts are best for dry environments since moisture will cause them to rust.
    Surface Smoothness—The lower the microinch value, the smoother the finish and the less friction it will cause on the bearing.

    Telescoping Delrin® Acetal Round Tubes

    Image of Product. Front orientation. Plastic. 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.

    Image of Product. Front orientation. Plastic. Telescoping UHMW Polyethylene Round Tubes.
    Telescoping tubes, also known as bushing stock, slide over rods and inside shafts to increase or decrease the diameter. Their precise sizing allows ascending sizes to fit inside each other to create a thicker wall. These impact- and wear-resistant tubes offer 360° protection from scrapes and strikes to wires, cords, and anything that can slide through them. UHMW has a low-friction surface that resists sticking and binding.
