Ball joint, smooth and play-free. We manufacture the M3 ball joint carrier from an extremely strong plastic with a very low proportion of Teflon. Hence the unsurpassed wear resistance. The ball is provided with two approaches as screw-on surfaces (distance 6mm). Hole diameter 3 mm. The hard chrome-plated ball is ideal for mounting in our fork rudder lever or fork servo lever. With this combination, backlash-free and smooth power transmission is possible in the long term, even under extreme loads. Areas of application are large model aircraft, jet models, large helicopter models and car models. The plastic carrier also has a molded hexagon on the shaft to facilitate assembly.
