Additional Specifications |
The addition of MDS gives these tubes exceptional wear resistance along with a self-lubricating surface. They're made of cast nylon 6, making them easier to machine and better electrical insulators than other MDS-filled nylon tubes. Tubes can be used to fabricate pulleys, bushings, and bearings installed in hard-to-reach areas where adding a lubricant would be difficult. This material is comparable to Nylatron and Nycast.
Oversized Tolerance—Oversized tubes have an oversized OD and an undersized ID for finishing to the sizes listed.
