This product is a 1 piece rod end spherical bearing with metric threading. It is designed for linkage applications that require a pivot joint capable of accommodating angular misalignment while transmitting load. The range spans sizes from M5 to M50, with options for male or female thread, and variants associated with SA, SI, and T/K ball joints. A right thread variant is available, including SI12 (M12). Key benefits Enables pivoting motion with misalignment compensation in mechanical linkages, improving system reliability and reducing binding. Spherical bearing design provides smooth rotation at the joint and distributes load through the bearing interface. Flexible connection options with both male and female metric threads to suit a variety of mounting configurations. Wide size range (M5, M6, M8, M10, M12, M14, M16, M18–M50) supports multiple applications without requiring adapters. Right thread option available, including SI12 (M12), to match mounting orientation and thread direction requirements. Ball joint variants SA, SI, and T/K offer different mounting interface styles to fit existing systems. Key attributes Function: rod end spherical bearing for mechanical linkages and ball joint connections. Thread type: metric threaded, righthand thread (Right Thread). Specific variant SI12 (M12) is provided as the rightthread option. Connection options: available in male and female thread configurations. Size range: M5, M6, M8, M10, M12, M14, M16, M18–M50. Ball joint variants: SA, SI, T/K. Material: not specified in the listing. Performance: designed for standard rodend bearing usage in linkage and articulation applications. Two to three use cases Robotic arms and automated assemblies: connects actuators to linkages, allowing precise pivoting while accommodating angular movement. Industrial machinery and automation systems: serves as a pivot joint in control arms, guide mechanisms, and transfer links where misalignment must be tolerated. CNC machines, packaging lines, and general machinery: used in dynamic linkages that require smooth articulation and reliable rotation with metric threaded mounting. Notes The SI12 (M12) rightthread variant is specified for rightthread applications. The product supports multiple metric thread sizes from M5 through M50 and includes male and female configurations as well as SA, SI, and T/K ball joint styles. Material details are not provided in the listing. Please refer to the exact product variant for material specification and exact threading compatibility.
