High-precision adjustable stroke cylinder with dual-position locking mechanism, featuring micrometer-style stroke adjustment (±0.5mm repeatability). The anodized aluminum construction provides corrosion resistance for harsh environments. Includes magnetic piston for position sensing compatibility.

Typical Applications:

• Variable height positioning in automated assembly lines
• Clamping force adjustment in CNC fixtures
• Material handling with variable stroke requirements
• Packaging machine ejection systems
• Plastic injection molding ejectors

Operation tip: Always lubricate with ISO VG32 hydraulic oil (N32) before initial use. For precise adjustment, use the hex wrench to loosen the lock nut before rotating the stroke adjustment dial. Re-tighten to 4.5N·m torque after adjustment.

Note: When used at maximum stroke extension, reduce maximum operating pressure by 20% to prevent side load stress. Not recommended for vertical downward thrust applications without external guides.
