High quality bearing, consistent motion resistance between multiple bearings. Exact replacement for Hiller UH12D tail rotor rod ends.

A quality built bearing, the same brand and specification as as the Vans supplied aileron rod end bearing, but with sufficient extra 3/8” male thread so that you can connect your aileron rod to the joy sticks and bell cranks, without worrying about having too little thread left for a secure connection to the aileron rod itself. A very worthy investment this one!
