Telescoping Tight-Tolerance Hardened Ultra-Wear-Resistant 440C Stainless Steel Round Tubes
 |
Tubes Sold Separately |
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.

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.

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.
