High-torque industrial cylinder engineered for heavy-duty linear motion applications. Features precision honed tube with hard anodized surface (25μm thickness) for exceptional wear resistance. The dual-chamber design maintains consistent thrust even under side load conditions. Includes magnetic piston (DIN EN 175301-803) for position sensing compatibility.
- Metal stamping press ejection systems
- Automotive welding fixture positioning
- Injection molding machine clamp mechanisms
- Heavy conveyor gate actuation
- Construction equipment hydraulic assist
Installation protocol:
Requires perpendicular mounting surface with flatness ≤0.1mm/m.
Lubricate rod with ISO VG32 hydraulic oil before initial operation.
Maintain 0.3–0.5mm clearance between rod and bushing during alignment.
Pressure caution:
Never exceed 1.2MPa burst pressure. Shock loads above 1,500N
may cause bushing deformation. Install external shock absorber
for impact applications.
