The SI40BX145 features a precision-machined aluminum barrel with integrated mounting grooves, designed for medium-duty industrial automation. Its magnetic piston enables position sensing compatibility (sensor sold separately). The dual adjustable cushions minimize end-impact noise while maintaining 0.5 million cycle durability. Optional heat-resistant seals (up to 120℃) available for special applications.
- Automated assembly line clamping mechanisms
- Packaging machine lid press systems
- CNC machine tool door actuators
- Plastic injection molding ejectors
- Conveyor sorting gate controls
Installation note:
Lubricate rod with silicone grease (MIL-G-81322) before initial use.
For vertical mounting, maintain ≤0.15mm/m alignment tolerance.
Use locknuts (M16×1.5) with 25-30Nm torque for load connections.
