High-performance industrial cylinder designed for heavy-duty applications requiring precise linear motion control. Features precision honed tubing and multi-layer sealing system for minimal internal leakage. The corrosion-resistant construction includes an anodized aluminum barrel and double chrome-plated piston rod with hardened surface (HRC 40-50). Requires 40μm filtered air and regular lubrication intervals (every 3 months under normal operation).
- Automotive production line clamping systems
- Metal stamping press ejection mechanisms
- Packaging machinery pusher assemblies
- Plastic injection molding machine core pulls
- Heavy material handling gates/doors
Installation note:
Maintain 0.1-0.3mm clearance between rod end and load during alignment.
For vertical installations exceeding 45° angle, use rod-end support brackets.
Lubricate through air supply (ISO VG32 recommended).
