The 2-26 piston is a key component used in certain models of rotary hammer drills or demolition hammer machines, specifically in models like the Bosch GBH 2-26. These machines are commonly used in construction and masonry for drilling and chiseling through concrete, stone, and similar hard materials.

The piston plays an essential role in the hammering mechanism of the machine. In a rotary hammer, the piston is part of a pneumatic system that converts rotational motion into a forward hammering action, driving the drill bit into hard materials. The process works as follows:

Pneumatic System: The motor drives a crankshaft that moves the piston inside a cylinder.
Pressure Build-Up: As the piston moves back and forth, it compresses air, creating a high-pressure environment.
Hammering Action: The compressed air moves a striker that hits the drill bit, creating the hammering force needed for efficient drilling or chiseling.
Spare parts for a 2-26 piston typically include components like:

Piston rings or seals
Connecting rods
Cylinder housings
These parts ensure the piston functions smoothly within the hammer machine and that the pneumatic system works efficiently for continuous hammering performance.
