Bore 1.0000 / 1-12 ThreadJMR16-2H(T) / JML16-2H(T) presenta un diámetro interior (B) de 1.0000″ y un diámetro del cuerpo (D) de 2.950″. La longitud total del cuerpo (AM) es de 4.500″; el enrosque de rosca (CM) mide 2.500″. La anchura (W) es de 1.375″ y el espesor del cuerpo (T) es de 1.000″. Peso aproximado: 2.464 lbs. El vástago de servicio pesado proporciona un diámetro de cuerpo sobredimensionado para una mayor capacidad de carga manteniendo el mismo diámetro interior.
Con una carga radial estática de 43,555 lb y un ángulo de desalineación de ±17°, esta cabeza de bieleta macho con rosca exterior 1-12 UNF 3A resulta adecuada para maquinaria industrial de extrema exigencia, bielas estructurales grandes y equipos pesados. El cuerpo de acero al carbono tratado térmicamente y con zincado amarillo proporciona una resistencia fiable a la corrosión para aplicaciones industriales y automotrices.
Disponible en versión estándar (JMR16-2H / JML16-2H) o con revestimiento de PTFE (JMR16-2HT / JML16-2HT) para un funcionamiento sin mantenimiento y sin lubricación. Opción de espárrago (sufijo S) y opción de engrasador (sufijo Z) disponibles. El cuerpo es de acero al carbono, tratado térmicamente y con zincado amarillo; la pista es de acero aleado para una alta capacidad de carga.

The JMR16-2H(T) / JML16-2H(T) is a 1.0000" bore, 1-12 UNF 3A external-thread male rod end in the JM(-T)-JF(-T) series, sized for extreme-duty industrial machinery, large structural linkages, and heavy equipment.
The heavy-duty shank provides an oversized 2.950" body diameter (D) for increased load capacity while maintaining the same 1.0000" bore size as the standard-shank version in this series.
The JMR16-2H(T) / JML16-2H(T) is rated at 43,555 lb static radial load with up to ±17° of angular misalignment.
Overall body length (AM) is 4.500", thread engagement (CM) measures 2.500", width (W) is 1.375", and body thickness (T) is 1.000" — approximate weight is 2.464 lb. Confirm these dimensions against your mounting clearance before ordering.
Bore (B) is 1.0000" and the external thread is 1-12 UNF 3A.
Ball: 52100 bearing steel, precision ground, heat treated, hard chrome plated. Body: Carbon steel, yellow zinc plated. Race: Alloy steel, PTFE lined optional. Alongside the standard version (JMR16-2H / JML16-2H), SYZ offers a PTFE-lined -T version (JMR16-2HT / JML16-2HT) for maintenance-free, lubrication-free operation, plus a stud option (suffix S) and a grease-fitting option (suffix Z). Technical drawing 72443 is available on request.
