Overview
AM AF 2-Piece Aluminum Rod Ends Product Overview
AMR4 / AML4: диаметр отверстия (B) — 0.2500″, диаметр корпуса (D) — 0.750″; шар из стали 0.500 диаметром 52100″ с твёрдым хромированием работает в обойме из литьевого армированного нейлона/PTFE. Общая длина корпуса (AM) — 1.562″, длина свинчивания (CM) — 1.000″. Ширина (W) — 0.375″, толщина корпуса (T) — 0.281″, приблизительный вес 0.030 lbs.
Шарнирная головка с резьбой 1,433/16-1 UNF 4A, рассчитанная на статическую радиальную нагрузку 28 lb при угле несоосности ±3°, подходит для лёгких рычагов, прецизионных механизмов и небольших управляющих узлов, требующих компактных размеров и низкого трения.
Доступны исполнения с правой (AMR4) и левой (AML4) резьбой. Усиленная обойма из нейлона/PTFE постоянно самосмазывающаяся и самогерметизирующаяся — пресс-маслёнки и смазка при обслуживании не требуются. Исполнение со шпилькой — по запросу (добавьте суффикс S, напр. AMR4S / AML4S). Корпус выточен из авиационного алюминия 7075-T6 с цветным анодированием; доступен в красном, чёрном, необработанном (Plain), фиолетовом, синем, зелёном и розовом цветах.

FAQ
AM AF 2-Piece Aluminum Rod Ends Frequently Asked Questions
What is the AMR4 rod end used for?
The AMR4 / AML4 is a 0.2500" bore, 1/4-28 threaded 7075-T6 aluminum male rod end, used for light-duty linkages, precision mechanisms, and small control assemblies requiring compact dimensions and low friction.
What are the key body dimensions of the AMR4?
Bore (B) is 0.2500", body diameter (D) is 0.750", overall body length (AM) is 1.562", thread engagement (CM) is 1.000", width (W) is 0.375", and body thickness (T) is 0.281", weighing approximately 0.030 lbs.
What load and misalignment rating does the AMR4 carry?
The AMR4 is rated at 1,433 lb static radial load with ±16° misalignment angle.
What is the AMR4 made of?
The body is 7075-T6 aircraft aluminum, color anodized red or black, the 0.500" 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.
What is the difference between AMR4 and AML4?
AMR4 is the right-hand thread version and AML4 is the left-hand thread version of the same 0.2500" male rod end — order the matching pair for turnbuckle-style or fixed-end linkage assemblies as your design requires.
Can SYZ supply the AMR4 with a stud or in a different color?
Yes. A stud configuration is available on request (add suffix S, e.g. AMR4S / AML4S), and the anodized aluminum body is available in Red, Black, Plain, Purple, Blue, Green, and Pink — confirm color and stud option when requesting a quote.
