Component Specifications

Definition
The piston head is a critical reciprocating component in impeller/piston assemblies that seals against cylinder walls and transfers hydraulic or pneumatic pressure into linear mechanical force. It features precisely machined surfaces, sealing grooves, and mounting interfaces for connecting rods or shafts.
Working Principle
Operates on fluid dynamics principles where pressurized fluid (hydraulic oil or compressed air) acts upon the piston head surface area, creating force that drives linear motion. The piston head transfers this force through connecting mechanisms to perform work.
Materials
Typically forged or cast aluminum alloy (e.g., 6061-T6, 7075-T6) for lightweight applications, or hardened steel (e.g., AISI 4140, 4340) for high-pressure systems. May include bronze or composite wear rings.
Technical Parameters
  • Hardness HRC 40-60 (steel), HB 80-120 (aluminum)
  • Surface Finish Ra 0.4-0.8 μm
  • Temperature Range -40°C to +200°C
  • Diameter Tolerance ±0.01 mm
  • Operating Pressure Up to 300 bar
Standards
ISO 4393, DIN 332, ISO 3320, DIN 24334
