Precision-adjustable industrial cylinder featuring dual-end stroke limitation with ±75mm total adjustment capacity. The hardened piston rod and triple-lip seal design ensure over 3,000km service life under standard conditions. Includes built-in magnetic sensor slots (M5x0.8 thread) for position feedback devices.

Typical Applications:

• Packaging line product positioning gates
• CNC machine tool clamping mechanisms
• Automated warehouse stacker position control
• Plastic injection molding ejector systems
• Glass cutting machine stroke adjustment

Installation Guidelines: Maintain 0.5-1mm clearance between adjustment screws and stoppers during alignment. Lubricate with ISO VG32 hydraulic oil before initial operation. For vertical mounting, install rod-end support bracket (ASNU-63 recommended).

Maintenance Note: Recalibrate stroke settings every 50,000 cycles. Avoid over-tightening adjustment screws (max torque 2.5N·m). Drain moisture from air ports weekly in high-humidity environments.
