Threaded-body cylinders

Product catalog summary
Overview
Threaded-body cylinders are designed for high-pressure applications up to 500 bar, available in single and double-acting variants. They feature nine different body types and are suitable for various industrial applications due to their compact design and efficient oil supply through drilled channels.
Specifications
  • Operating Pressure: Up to 500 bar
  • Push Force: 2.5 to 62.8 kN
  • Piston Stroke: 4 to 40 mm
  • Body Types: 9 variations
  • Hydraulic Connection: Drilled channels or pipe thread
  • Sealing Types: Cutting edge, sealing ring, O-ring, and back-up ring
  • Materials: Piston made of case-hardening steel, body of free-cutting steel
Functionality
  • Single Acting: Utilized as clamping cylinders with spring return, requiring minimal clamping strokes.
  • Double Acting: Suitable for linear drives with longer piston strokes, ensuring efficient return strokes.
Technical Information
  • Tightening Torque: Essential for maintaining tightness and functionality, varies with thread and sealing type.
  • Admissible Piston Side Load: 3-5% of push force at max pressure, depending on type.
  • Seals and Temperature: NBR for temperatures -30 to +80°C, FKM for -20 to +150°C.
  • Leakage: Cylinders are leakage-free in static conditions, allowing micro-oil film for lubrication.
Installation and Maintenance
  • Mounting Position: Flexible, unless specified otherwise.
  • Bleeding: Necessary during startup to prevent air in the oil, which can cause functional issues.
  • Accessories: Various contact bolts and coupling pins available for different applications.
Applications
  • Threaded-body cylinders can be directly screwed into clamping bars or fixture bodies, allowing for compact setups with minimal cylinder distances.
  • Single-acting cylinders are preferred for applications requiring short clamping strokes.
  • Double-acting cylinders are versatile for use as linear drives in cycle-dependent installations.

Important technical information Application Threaded-body cylinders can be screwed directly into clamping bars or fixture bodies. Hydraulic oil is supplied through drilled channels. This enables very small cylinder distances in multiple clamping fixtures. Sealing type The screwed-in cylinder bodies are sealed by Air in the oil prolongs the clamping time considerably and leads to function troubles. Therefore bleeding has to be effected during start up. As it is not possible to bled the threaded-body cylinders individually, screw plugs should be provided in the fixture body at the end of the drilled...
