High-precision industrial cylinder optimized for heavy-duty cycles, featuring wear-resistant rod guides and corrosion-resistant construction. The dual adjustable cushions minimize end-impact noise while maintaining positioning accuracy. Compatible with auto-switch sensors via T-slot mounting. Requires 40μm filtered air with ISO 8573-1:2010 class standards.

Typical Applications:
  • Injection molding machine ejectors
  • Palletizing robot end-effectors
  • Automotive assembly line clamping
  • Steel mill conveyor gate actuators
  • Packaging machine vertical lifts
Installation tip: Maintain 0.5–1mm alignment tolerance during mounting. For vertical installations, use rod-end support brackets when stroke exceeds 150mm. Lubricate every 3,000km stroke distance under continuous operation.
Critical note: Avoid side load exceeding 150N. Use guided cylinder configurations for moment load applications. Maximum permissible lateral play: ±1.2°
