High-torque industrial cylinder optimized for heavy-load applications requiring precise linear motion. Features wear-resistant dual-seal structure and anti-rotation piston rod. Optional magnetic piston version (SI125BX125SH-M9) available for position sensing. Requires filtered, lubricated air (ISO 8573-1 class 3.4.2).
- Plastic injection molding machine ejectors
- Automotive assembly line clamping devices
- Steel mill material handling systems
- Packaging machinery compression units
- Hydraulic press auxiliary positioning
Installation note:
Use alignment jigs during mounting to prevent side load. Lubricate through air port
(ISO VG32 equivalent) before initial operation. Maintain ≥50mm clearance for rod extension.
Critical parameters:
Max piston speed 500mm/s (with cushion). Minimum operating pressure 0.1MPa for stable movement.
Not recommended for vertical downward thrust applications without counterbalance.
