The DU-BRO Heavy Duty Ball Links are built for RC hobbyists who want strong, smooth, and reliable linkage components. These ball links provide friction-free movement, making them perfect for control surfaces, steering systems, throttle linkages, and other areas where accuracy and durability are important.
Each ball link uses a burnished, nickel-plated brass ball that rotates smoothly and resists wear. This gives you consistent, slop-free control even in high-stress models such as aerobatic airplanes, helicopters, RC cars, drones, and boats. The heavy-duty design ensures long-lasting performance, even under vibration or heavy load.
Every assembly includes everything you need for a secure installation:
Socket head cap screw
Brass shim
Nylon insert lock nut
These parts work together to provide a tight, vibration-resistant connection that stays secure through repeated flights and mechanical movement.
Ball link assembly weights:
#899 - 3.5 g
#2262 - 3.5 g
#2266 - 3.5 g
#2268 - 4.5 g
#2321 - 3.5 g
Proudly Made in the USA, DU-BRO Heavy Duty Ball Links are trusted by RC builders for their strength, smooth operation, and long-term reliability. Whether you're building a new model or replacing older hardware, these ball links deliver dependable performance you can count on.
