High-thrust industrial cylinder designed for heavy-duty linear motion applications. Features dual cushioning adjustment screws for smooth deceleration and reduced impact noise. The X-series construction enhances lateral load capacity by 30% compared to standard SI models through reinforced tie rods. Integrated magnet (D-C73 type) enables position feedback with compatible sensors.
- Metal stamping press ejection systems
- Automotive welding fixture positioning
- Paper roll clamping in printing machinery
- Plastic injection mold core pulling
- Heavy conveyor gate actuators
Installation Guidelines:
Use M12×1.75 mounting bolts (grade 8.8 or higher) with spring washers.
Maintain 0.5mm minimum clearance between magnetic switch and cylinder body.
For vertical mounting, install air vent filter in upper port. Lubricate rod weekly in high-cycle (>500 strokes/hour) applications.
