Heavy-duty industrial cylinder designed for high moment load applications, featuring precision-guided piston movement and corrosion-resistant construction. The triple-seal design (primary seal, secondary seal, and rod wiper) ensures reliable operation in contaminated environments. Requires ISO VG32 hydraulic oil or equivalent for lubrication when used in high-cycle applications (>1 million cycles).
- Metal stamping press ejection systems
- Automotive welding fixture positioning
- Injection molding machine core pulling
- Heavy conveyor gate actuation
- Paper mill roller compression control
Installation guidelines:
Align cylinder axis within 0.2mm perpendicularity tolerance.
Use flexible couplings for stroke-end force absorption.
Maintain 0.5mm minimum clearance between rod end and load during thermal expansion.
- Relubricate every 500km cumulative stroke movement
- Replace rod wiper after 3 million cycles
- Inspect piston seal leakage rate annually (max 5cc/min @1MPa)
