High-load industrial cylinder featuring precision honed tubing and triple sealing system. The SI125BX750S combines heavy-duty construction with precision control through its adjustable cushioning mechanism. Requires 5-40μm filtered lubricated air (ISO 8573-1 class 3-4-3). Built-in magnet (D-M9NW) enables position feedback when used with magnetic sensors.
- Press machine ejection systems
- Automotive welding fixture actuation
- Steel coil handling equipment
- Plastic injection molding machine core pulls
- Heavy conveyor gate controls
Installation note:
Ensure alignment tolerance ≤0.2mm/m during mounting. For vertical installations,
use rod-down orientation and install an air dryer to prevent condensation pooling.
