A high-cycle industrial workhorse featuring precision honed tubing and wear-resistant seals. The SI40BX90S combines rapid response (≤0.3s full stroke actuation at 0.6MPa) with anti-rotation rod guidance, making it ideal for repetitive linear motion tasks. Requires 40μm filtered compressed air and monthly lubrication checks in continuous operation.
- Automated assembly line clamping mechanisms
- Packaging machine ejection systems
- CNC machine tool part positioning
- Conveyor gate actuators
- Automotive welding fixture controls
- Standard seals: 5,000 km (3,100 miles) at 0.5MPa
- High-durability option: 8,000 km (5,000 miles)
