One piece rod end spherical bearing with metric threads and left-thread option. This listing covers SA SI T/K ball joint variants and supports male or female connections. Sizes range from M5 to M50, including SI18 (M18) in the left-thread configuration. Key benefits - Enables smooth cantilevered articulation in linkages while accommodating angular misalignment. - Versatile metric threaded design for straightforward installation across equipment. - Left-thread version simplifies mounting in configurations where right-thread parts would be impractical. - Broad size range (M5–M50) to fit diverse mechanical assemblies, improving compatibility and inventory efficiency. - Sold as a single piece, providing a precise, ready-to-install rod end bearing for quick project setup. Key attributes - Type: Rod end spherical bearing (ball joint) - Thread: Metric threaded; left-thread variant - Connection options: Male and Female versions - Sizes: M5, M6, M8, M10, M12, M14, M16, M18–M50 (SI18/M18 included) - Ball joint form: SA SI T/K variants - Material: Not specified in the listing - Configuration: 1 piece per unit Applications and use cases - Robotic arms and automation linkages requiring a left-thread rod end for compact mounting - CNC machines, automation equipment, or machinery where precise pivoting and robust linkage joints are needed - Automotive or industrial equipment where spherical bearing joints with metric threads improve alignment tolerance and durability Notes for selection and installation - Confirm required thread size (M5–M50) and ensure the left-thread variant matches mounting orientation - Choose the appropriate ball joint style (SA SI T/K) for compatibility with mating components - If material specification is important, verify material with the supplier before purchase
