PHS Series

Product catalog summary
Overview: The document provides technical specifications and details for the PHS-Series power chucking cylinders, designed for high rotational speeds suitable for modern CNC lathes. These cylinders are compact with an aluminum cylinder for low moment of inertia and are equipped with built-in, pilot-operated check valves to retain pressure during hydraulic failure.
Specifications:
  • Working pressure: Up to 40 bar
  • Models: PHS-1036, PHS-1246, PHS-1552, PHS-1875, PHS-2091
  • Max Pull (kg): Ranges from 2300 to 8300
  • Piston Diameter (mm): Ranges from 105 to 205
  • Piston Travel (mm): Ranges from 15 to 30
  • Max Speed (rpm): Ranges from 3800 to 8000
  • Leakage at 30 bar & 50°C (kg): Ranges from 3 to 4.5
  • Weight (approx kg): Ranges from 12 to 36
Design Features:
  • Open center with safety valve
  • Available with or without coolant collector and proximity sensors
  • Supplied with coolant collector and stroke-sensing proximity switches
  • Designed for high rotational speeds
Dimensional Data: The document includes detailed dimensional data for each model, specifying measurements such as ØA H8, ØB H8, ØD f7, ØE h7, and others, which are critical for installation and compatibility with various systems.
Applications: These power chucking cylinders are suitable for use in CNC lathes, providing reliable performance in high-speed operations.
