  • Lubrication: Pre-lubricated (recommended relubrication every 3,000km)

High-precision dual-axis cylinder featuring micrometer-style stroke adjustment (±0.5mm repeatability) through its unique rotating end cap design. The twin rod configuration provides enhanced rigidity and alignment accuracy, with integrated shock absorption to minimize vibration during abrupt stops. Includes built-in auto-discharge valves for stroke adjustment under pressure.

Typical Applications:
  • Precision positioning in CNC tool changers
  • Variable height clamping systems in fixture tables
  • Material handling with adjustable gripping depth
  • Automated assembly line height compensators
  • Printing press roller gap adjustment
Installation note: Requires alignment within 0.2mm/m perpendicularity tolerance. Use flexible couplings when connecting to rigid structures. For full stroke adjustments, reduce system pressure below 0.2MPa before rotating adjustment dial.
Maintenance Protocol:
  • Relubricate every 6 months with ISO VG32 hydraulic oil
  • Inspect rod seals after 500,000 cycles
  • Max side load: 30N (perpendicular to rod axis)
  • Storage: Keep vertical to prevent rod sagging
