4-40 Heavy Duty Ball Links (12)
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

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 youre building a new model or replacing older
hardware, these ball links deliver dependable performance you can count on.
