If you want a linkage that operates cleanly, reduces friction, and stays reliable over time, this swivel ball link is an excellent choice for many different types of models.\u003c\/p\u003e\n\u003cp data-start=\"511\" data-end=\"917\"\u003eEach link features a burnished, nickel-plated brass swivel ball. This ball rotates freely inside its socket, allowing your control rod to move smoothly in any direction. The nickel plating helps the ball resist wear and corrosion, so it continues to perform well even after many flights. This design helps reduce binding and slop—two common issues that can affect how your aircraft responds in the air.\u003c\/p\u003e\n\u003cp data-start=\"919\" data-end=\"989\"\u003eThe DU-BRO Swivel Ball Link comes as a complete assembly, including:\u003c\/p\u003e\n\u003cul data-start=\"990\" data-end=\"1058\"\u003e\n\u003cli data-start=\"990\" data-end=\"1021\"\u003e\n\u003cp data-start=\"992\" data-end=\"1021\"\u003eA socket head cap screw\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1022\" data-end=\"1042\"\u003e\n\u003cp data-start=\"1024\" data-end=\"1042\"\u003eA brass shim\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1043\" data-end=\"1058\"\u003e\n\u003cp data-start=\"1045\" data-end=\"1058\"\u003eA hex nut\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-start=\"1060\" data-end=\"1386\"\u003eThese parts work together to create a strong, secure, and easy-to-install connection. The brass shim improves alignment and smooth movement, while the cap screw and hex nut hold everything tightly in place.
