Telescoping Tight-Tolerance Hardened Ultra-Wear-Resistant 440C Stainless Steel Round Tubes
Adjust the diameter of your shaft or rod by nesting these tubes inside each other. They're also known as precision shim stock. You can be confident in their precision since they're held to a tight diameter tolerance. They also come hardened for extra wear and abrasion resistance.
With even more carbon than 440A, 440C stainless steel is one of the hardest types of stainless steel. It maintains its corrosion resistance in temperatures as hot as 800° F.

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.

Weldable 4130 Alloy Steel Round Tubes
 |
Also known as chrome-moly steel, these 4130 alloy steel round tubes have low carbon content for good weldability. They’re often used for roll cages and frames. To increase their wear resistance, you can harden them with heat treating.

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.

Steel-Backed PTFE Sheets
 |
A layer of tin-plated steel adds structural support and makes this PTFE easy to form. Bend it to fit inside V-blocks and other channels, or cut it to form wear strips and thrust bearings. PTFE is naturally slippery, so it works well in parts that slide and roll.
