Component Specifications

Definition
The actuator rod/piston is a critical linear motion component within insertion actuators, designed to translate hydraulic or pneumatic energy into controlled mechanical force. It consists of a cylindrical rod that moves linearly within a cylinder bore, sealed with appropriate rings to prevent fluid leakage. This component provides the precise force and stroke required for insertion operations in automated assembly systems, ensuring accurate positioning and repeatable performance.
Working Principle
Operates on the principle of fluid dynamics (hydraulic or pneumatic). Pressure differential across the piston creates linear force according to Pascal's law (F=P×A). The rod transmits this force to the external load while maintaining alignment through precision bearings or bushings.
Materials
Typically manufactured from hardened alloy steel (AISI 4140/4340) or stainless steel (17-4PH) with surface treatments: chrome plating (15-30μm) for wear resistance, nitriding for hardness (50-65 HRC). Sealing surfaces polished to Ra 0.2-0.4μm.
Technical Parameters
  • Diameter 10-100 mm
  • Hardness 50-65 HRC
  • Load Capacity 500-50000 N
  • Stroke Length 50-1000 mm
  • Surface Finish Ra 0.2-0.4 μm
  • Operating Pressure Up to 300 bar (hydraulic), 10 bar (pneumatic)
  • Straightness Tolerance 0.01 mm/100 mm
Standards
ISO 6431, ISO 15552, DIN ISO 21287, DIN 24554

Frequently Asked Questions

What is the difference between actuator rods for hydraulic vs pneumatic systems?

Hydraulic rods are designed for higher pressures (up to 300 bar) with thicker cross-sections and specialized sealing, while pneumatic rods operate at lower pressures (typically 6-10 bar) with lighter construction and different seal materials.

How often should actuator rods be inspected for wear?

Visual inspection every 500 operating hours, dimensional measurement every 2000 hours or 6 months. Replace if wear exceeds 0.1mm diameter reduction or shows scoring deeper than 0.05mm.

Can actuator rods from different manufacturers be interchanged?

Only when dimensional specifications (ISO 6431/15552), mounting interfaces, and material properties match exactly. Always verify compatibility with cylinder bore and seal specifications.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
