Hirobo HI2525012 D5mm Ball H=9.5, 10pcs pack general helicopter ball joints  [HI2525012]

D5mm ball for helicopter linkages

This Hirobo D5mm ball set (HI2525012) is a small-scale replacement part intended for RC helicopter assemblies where a D5mm ball with a 9.5mm height is required. The pack contains 10pcs suitable for routine maintenance and part swaps on general helicopter linkages.

Use this ball where a compact ball joint is called for in control linkages or small rotating connections. Before fitting, confirm the mating rod, socket diameter and retaining method used on your model to ensure secure engagement and minimal play.

When servicing control linkages, inspect each ball for wear or deformation and replace as a matched set when multiple joints show signs of looseness; consistent ball geometry helps maintain predictable control response and easier tuning.
