This Kyosho MB026 pillow ball is an RC-scale replacement part designed for Mini-Z MB-010 series linkage and steering joints. The listing indicates M2 thread sizing and a pack quantity of 8 pcs, matching typical miniature chassis ball link locations commonly found on Mini-Z setups.
Functionally, the pillow ball serves as a compact ball-socket interface that locates linkage pins while allowing articulation. On a Mini-Z MB-010 chassis it is used where a small, low-profile ball joint is needed to control tie-rods, steering links, or small suspension link points, helping maintain repeatable geometry during setup and use.
Installation and service considerations focus on fitment to M2 threaded posts and ensuring correct seating in the ball cup. Inspect mating surfaces for wear before installation, replace in matched sets if multiple joints show play, and verify free movement across the intended motion range after fitting.
