Tight-Tolerance Hardened 440C Stainless Steel
With a diameter that’s held to a close tolerance, this material is hardened for increased wear and abrasion resistance. 440C is one of the hardest types of stainless steel after heat treating. This material maintains its corrosion resistance in temperatures up to 800° F.
Tubes are also known as precision shim bushing stock. Use them to decrease a shaft diameter or increase a rod diameter. They are sized so that each tube fits into the next larger size to create a telescoping tube.

Wear-Resistant Easy-to-Machine Delrin® Acetal Resin Tubes
- Color: White or Black
- Temperature Range:
6" Lengths: 0° to 180° F
All other sizes: -20° to 180° F - Tensile Strength: 7,690 psi (Good)
- Impact Strength: 1-1.5 ft.-lbs./in. (Poor)
- Hardness: Rockwell R120-R122 (Hard)
- For Use Outdoors: No
- Specifications Met: See table
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.
Tight-tolerance tubes that are 6” long are also known as bushing stock. You can slide them over rods to increase the OD, or into shafts to decrease the ID. Their precise sizing also allows ascending sizes to fit inside of each other to increase the wall thickness.

Slippery UHMW Polyethylene Tubes
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.
Tight-tolerance 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.

Metal-Backed Slippery PTFE
- Color: Black
- Temperature Range: -330° to 480° F
- For Use Outdoors: No
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.
