MDS-Filled Cast Nylon Rod

Manufacturer part: 2889K126

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.
