The CMR6-8(T) / CML6-8(T) is a male rod end with an integral 1/2-20 threaded stud and a 0.3750" bore ball, designed to thread into a matching female-threaded fitting, clevis, or adapter. It suits suspension systems, steering linkages, and mid-range industrial control applications.
The CMR6-8(T) / CML6-8(T) has a 0.3750" bore (B), a 1/2-20 UNF 3A thread, and a 1.125" body diameter (D). Overall body length (AM) is 2.125", thread engagement (CM) measures 1.375", width (W) is 0.500", and body thickness (T) is 0.359", weighing approximately 0.170 lbs.
The CMR6-8(T) / CML6-8(T) is rated at 8,278 lb static radial load with up to ±22° of angular misalignment, based on its 1/2-20 thread and 0.3750" bore size.
The ball is 52100 bearing steel, precision ground, heat treated, hard chrome plated, running in a metal-to-metal race (PTFE-lined race optional). The body is carbon steel, silver zinc plated.
The (T) suffix denotes the PTFE-lined version — CMR6-8T / CML6-8T — which replaces the standard metal-to-metal race with a PTFE liner for lubrication-free, maintenance-free operation. Order without the T suffix for the standard metal-to-metal race version.
