Nylatron(R) NSM Rod

Nylatron(R) NSM is cast nylon 6 carrying a proprietary solid-lubricant package - not oil and not molybdenum disulphide - and it is the wear grade of the nylon family by a wide margin. Its wear factor is 12 x 10^-10 against 90 for the MoS2 grades and 100 for unfilled cast nylon, roughly eight times better, and its published limiting PV is 15,000 psi-ft/min against 3,000, five times higher. Dynamic friction against steel is 0.18. The manufacturer rates dynamic load-bearing capacity up to five times that of conventional cast nylon grades and service life up to ten times longer.

It is specified for bearings, gears, wear pads, pulleys, sheaves, bushings, valve seats and seals, particularly higher-velocity unlubricated parts in large geometries where the cast route is the only way to get the size. Tensile strength is 11,000 psi on a 410,000 psi modulus, flexural strength 16,000 psi on a 475,000 psi flexural modulus, compressive strength 14,000 psi at 10% deflection, hardness Rockwell M80 (R110) and Shore D85. Continuous service is 200F and the melting point 420F. Know what you are buying: at 0.500 ft-lb/in notched impact and 20% elongation it is the brittlest of the cast family, tensile strength sits below plain cast nylon, and the manufacturer publishes no food-contact compliance. Grey is the only colour.
