Piston & Driving Mechanism parts diagram: 1 piston head, 2 piston rod, 3 piston ring, 4 guide bearing, 5 drive keyway, 6 o-ring set. 15 parts in 6 top-level items. — Piston & Driving Mechanism parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.

#	Part	Qty	What it does
1	Piston Head	1×	Large-diameter hardened steel disk that slides inside the [[hydraulic-rock-breaker-cylinder-barrel]], taking impact pressure.
2	Piston Rod	1×	High-tensile steel rod rigidly coupled to the piston head, transmitting striking force to the chisel.
3	Piston Ring	4×	Cast-iron segmented ring maintaining seal between piston and cylinder bore during strokes.
4	Guide Bearing	2×	Bronze or PTFE bushing at the front and rear guides aligning the piston axially without binding.
5	Drive Keyway	1×	Precision-machined longitudinal slot in the piston rod engaging a key inside the chisel for force transmission.
6	O-Ring Set	6×	Piston seals
