Overview
AM AF 2-Piece Aluminum Rod Ends Product Overview
AMR12-757 / AML12-757 features a 0.7570″ bore (B) and 1.750″ body diameter (D), with a 1.312″ hard-chrome-plated 52100 steel ball running in an injection-molded reinforced nylon/PTFE race. Overall body length (AM) is 2.875″, thread engagement (CM) measures 1.750″. Width (W) is 0.875″ and body thickness (T) is 0.687″, weighing approximately 0.290 lbs. The 0.7570″ bore is a special oversize dimension for applications requiring a slightly larger than standard #12 bore.
Rated at 13,400 lb static radial load with ±14° misalignment angle, this 3/4-16 UNF 3A threaded rod end suits high-load suspension, truck steering, and demanding industrial linkage applications.
Available in right-hand (AMR12-757) and left-hand (AML12-757) configurations. The reinforced nylon/PTFE race is permanently self-lubricating and self-sealing — no grease fittings or maintenance lubrication required. Stud configuration available on request (add suffix S, e.g. AMR12-757S / AML12-757S). Body machined from 7075-T6 aircraft aluminum, color anodized; available in Red, Black, Plain, Purple, Blue, Green, and Pink.

The AMR12-757 / AML12-757 is a 0.7570" bore, 3/4-16 threaded 7075-T6 aluminum male rod end, used for high-load suspension, truck steering, and demanding industrial linkage applications.
What are the key body dimensions of the AMR12-757?
Bore (B) is 0.7570", body diameter (D) is 1.750", overall body length (AM) is 2.875", thread engagement (CM) is 1.750", width (W) is 0.875", and body thickness (T) is 0.687", weighing approximately 0.290 lbs.
What load and misalignment rating does the AMR12-757 carry?
The AMR12-757 is rated at 13,400 lb static radial load with ±14° misalignment angle.
What is the AMR12-757 made of?
The body is 7075-T6 aircraft aluminum, color anodized red or black, the 1.312" ball is 52100 bearing steel, precision ground, heat treated, hard chrome plated, and it runs in an injection molded, reinforced nylon with PTFE race that is permanently self-lubricating and self-sealing, so no grease fittings are required.
