Oversized Easy-to-Machine Gray Cast Iron Rods and Discs
- Yield Strength: Not Rated
- Hardness: Rockwell C20 (Hard)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: Rockwell C50
- Specifications Met: ASTM A247
An oversized diameter allows for finishing to your exact requirements. Gray cast iron machines faster with less wear on cutting tools than most types of steel. It also absorbs vibration, so finished parts run quieter than those made of steel. It's often used for gears, pulleys, rollers, and bushings.

Wear-Resistant Easy-to-Machine Delrin® Acetal Resin Rods and Discs
Because these naturally slippery, wear-resistant rods and discs resist expanding when exposed to heat and moisture, they can be easily machined to close tolerances. They are a good choice for parts that require precision, such as gears, bushings, and bearings. Delrin® acetal resin is also known as acetal homopolymer; it is stronger and stiffer than acetal copolymer.

Wear-Resistant Easy-to-Machine Acetal Rods and Discs
- Color: White or Black
- Temperature Range: -20° to 180° F
- Tensile Strength: 9,135-9,700 psi (Good)
- Impact Strength: 1-1.5 ft.-lbs./in. (Poor)
- Hardness: Rockwell R120 (Hard)
- For Use Outdoors: No
- Specifications Met: FDA Compliant 21 CFR 176.170, FDA Compliant 21 CFR 177.2470, UL 94 HB
Made of naturally slippery acetal copolymer, these rods and discs are an economical alternative to Delrin® acetal resin. They offer similar wear resistance and are equally resistant to expanding when exposed to heat and moisture. They can be machined to close tolerances and are often used to make precision gears, bushing, bearings, and rollers.

MDS-Filled Easy-to-Machine Wear-Resistant Cast Nylon Rods and Discs
- Color: Black
- Max. Temperature: 230° F
- Tensile Strength: 10,000 psi (Good)
- Impact Strength: 1.4 ft.-lbs./in. (Poor)
- Hardness: Rockwell R110 (Hard)
- For Use Outdoors: Yes
- Specifications Met: ASTM D5989
An MDS additive provides exceptional wear resistance as well as a self-lubricating surface. Made of cast nylon 6, they’re easier to machine than other MDS-filled nylon rods and discs, plus they are better electrical insulators. Use them to fabricate gears, sprockets, wear strips, and other high-friction parts. This material is comparable to Nylatron and Nycast.

Easy-to-Machine Wear-Resistant Cast Nylon Rods and Discs
- Color: Off-White
- Temperature Range: -20° to 200° F
- Tensile Strength: 10,000 psi (Good)
- Impact Strength: 1.5 ft.-lbs./in. (Poor)
- Hardness: Rockwell R110-R115 (Hard)
- For Use Outdoors: No
- Specifications Met: ASTM D5989, FDA Compliant 21 CFR 177.1500, UL 94 HB
Because these cast nylon 6 rods and discs are easier to machine than standard nylon 6/6, they’re often made into pulleys, screws, bushings, and bearings. They’re also better electrical insulators. They have a wear-resistant, slippery surface that reduces friction. This material is comparable to Nylatron and Nycast.
