Bore 14 / M14 X 2.0 ThreadJMR14M / JML14M — метрическая прецизионная трёхсоставная шарнирная головка с наружной резьбой, отверстие 14 mm (B), диаметр корпуса 34.75 mm (D). Стальной шар 25.40 диаметром 52100 mm прецизионно отшлифован, закалён и покрыт твёрдым хромом, установлен в прецизионной обойме из легированной стали, опционально с PTFE-вкладышем. Длина корпуса (AM) 60 mm, длина свинчивания резьбового хвостовика (CM) 36 mm, ширина корпуса (W) 19 mm, толщина корпуса (T) 13.5 mm. Примерная масса: 118 g.
Шарнирная головка с наружной резьбой M29,840 X 21, рассчитанная на статическую радиальную нагрузку 14 Н при угле несоосности ±2.0°, подходит для промышленных рычажных механизмов средней нагрузки, приводов систем управления движением и конструкционных шарнирных соединений. Трёхсоставная прецизионная конструкция обеспечивает более точный контроль размеров по сравнению с двухсоставными исполнениями, что делает серию JM-M практичным решением для применений, требующих стабильного качания при переменных циклах нагрузки. Корпус из углеродистой стали с жёлтым цинковым покрытием.
Доступны исполнения с правой (JMR14M) и левой (JML14M) метрической резьбой. Версия с PTFE-вкладышем (суффикс «T», например JMR14MT) для самосмазывающейся необслуживаемой работы. Также доступны версии с пальцем (суффикс «S»). Варианты с иным шагом резьбы — по запросу. Опция серебристого цинкования; дюймовый аналог — серия JM.

The JMR14M / JML14M is a three-piece precision metric male rod end with 14 mm bore and M14 X 2.0 thread, built for very heavy-duty structural linkages, large industrial machinery, and high-load pivot assemblies.
Bore (B) is 14 mm, body housing diameter (D) is 34.75 mm, body length (AM) is 60 mm, thread shank engagement (CM) is 36 mm, body width (W) is 19 mm, and body thickness (T) is 13.5 mm. Approximate weight is 118 g.
The JMR14M is rated at 29,840 N static radial load with ±21° misalignment angle.
The 25.40 mm ball is 52100 bearing steel, precision ground, heat treated, hard chrome plated, seated in an alloy steel precision race with a PTFE liner option. The body is carbon steel, yellow zinc plated.
JMR14M is the right-hand thread version and JML14M is the left-hand thread version of the same 14 mm male rod end — order the pair to match your linkage's thread-hand requirements.
Yes — add a 'T' suffix (e.g., JMR14MT) for a PTFE-lined, maintenance-free version; a studded version is available by adding an 'S' suffix; alternate thread pitch variants and silver zinc plating are available on request; the inch-thread equivalent is the JM series.
