Heavy-duty industrial cylinder designed for high-momentum linear motion applications. Features precision honed tubing and multi-layered sealing system for ≤0.5 mm/s creep speed. Optional magnetic piston version (SI125X580-M9) available for position feedback. Compatible with ISO 15552 mounting accessories.

Typical Applications:
  • Automotive production line clamping systems
  • Steel coil handling equipment
  • Injection molding machine ejectors
  • Paper roll positioning in printing presses
  • Foundry mold compression mechanisms
Installation note: Requires minimum 0.5 MPa lubrication pressure during initial operation. For vertical mounting, use auxiliary rod support when stroke/rod ratio exceeds 5:1. Allow 50mm clearance behind end covers for cushion adjustment.
Maintenance: Relubricate every 1,000 km of cumulative stroke movement. Replace wiper seal after 3 million cycles in high particulate environments. Avoid side loads exceeding 350 N·m during operation.
