Series MT and FT Mil-Spec rod ends use Heim’s UNIFLON® PTFE liner and cartridge type construction. The cartridge type rod end consists of a spherical plain bearing mounted in a rod end body. The cartridge type rod end accommodates a PTFE liner for self-lubrication. This design is best suited for aircraft and military applications where material selection is a primary design consideration.
Mil-Spec Rod End Materials
This cartridge type design allows for the optimum selection of materials for ball, race and rod end body. MT and FT Series rod end bodies are made from 4340 alloy steel, heat treated to SAE-AMS-H-6875 and are cadmium plated. The outer races are made from heat treated 17-4PH stainless steel (AMS5643). The balls are made from heat treated 440C stainless steel (AMS5630). The Heim UNIFLON® PTFE liner is approved to SAE-AS81820. The MT and FT Mil-Spec rod ends are approved to SAE-AS81935.
