This is a single SI8TK right hand metric threaded rod end bearing from the SI8T/K family. The unit features a female (internal) thread and is finished in color PHSA18 with right thread. It covers bore sizes from 5 mm to 20 mm and is intended for precise, angularlinkage applications. Key benefits Enables a robust, articulating joint in compact linkages, allowing angular motion while guiding the rod end with a precision ball joint. Right hand metric threading provides secure mounting with compatible rods and hardware, reducing looseness under load. Wide bore option range (5 mm to 20 mm) supports a variety of shaft diameters and linkage designs, increasing interoperability with existing components. Color PHSA18 offers easy visual identification for assembly and maintenance. Key attributes Type: Right Hand Ball Joint / Rod End Bearing Model: SI8TK (SI8T/K series) Thread: Metric, Right Hand End: Female (internal) thread Bore sizes (available range): 5 mm, 6 mm, 8 mm, 10 mm, 12 mm, 14 mm, 16 mm, 18 mm, 20 mm Color: PHSA18 Quantity: 1 piece Applications and use cases Robotics and automation: connect servo or actuator linkages to create precise, pivoting joints with smooth motion and controlled alignment. CNC machines and 3D printers: serve as end points for moving linkages where compact, reliable ball joints are needed to accommodate misalignment and angular movement. Mechanical assemblies and hobby projects: ideal for building strong, adjustable linkages in hobby robotics, remotecontrolled vehicles, or custom machinery that requires a secure, controllable rod end bearing. How to use Select the bore size that matches the mating shaft diameter or mating rod. Thread the rod end into the corresponding mounting hole or housing using a compatible nut or lock washer as required by your design. Verify alignment and lubricate as per standard maintenance practices to ensure smooth operation and long service life. Note Material details are not specified in the listing; base selection and installation should follow standard engineering practices for metric threaded rod end bearings of the SI8T/K family.
