What is the function of a piston?

It is the moving component that is contained by a cylinder and is made gas-tight by piston rings. In an engine, its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod.

Hydraulic breaker piston

The piston material is SNCM616V,SNCM26V 20Cr2Ni4A,GCr15,40CrNiMo, the hardness of heat treatment is HRC58-62, and the surface roughness Ra value after fine grinding is ≤0.2μm. processed by machining center with high inner and outer precision. Multiple heat treatment to ensure the rigidity. The piston can be also customized.

Can hydraulic pistons be repaired?

The good news is that in many cases, a hydraulic cylinder can be repaired rather than replaced. However, the extent of the damage will determine whether repair is feasible.
