SP-30 PISTON INGCO (RH150028) D-68
🧰 What It Is
The piston is one of the core mechanical components inside a rotary hammer’s impact mechanism. It is a precision‑machined metal part that moves back and forth within the cylinder (SP‑22) to generate repeated impact forces that drive the hammer action.
In this tool design, the piston is part of the pneumatic hammering assembly that gives rotary hammers their powerful impact performance on hard materials like concrete and masonry.
⚙️ Technical Function
The piston performs several crucial roles:
1. Impact Generation
As the mechanism operates, the piston moves rapidly back and forth inside the cylinder.
The motion compresses air in the chamber, creating high‑pressure forces that deliver powerful blows.
2. Energy Transfer
The piston converts rotational and linear motion from the drive system into percussive impact energy.
This percussive energy is then transmitted to the bit for drilling or chiseling.
3. Guided Motion
The piston must have a very precise fit inside the cylinder to seal air pressure and allow efficient movement with minimal friction.
