The SI80X75S features a compact aluminum body with corrosion-resistant surface treatment, optimized for medium-duty linear motion. Its double-lip rod seal design ensures ≤0.5 mm/s creep speed at 0.3 MPa. The dual-cushion system reduces impact noise by 15 dB(A) compared to basic models. Requires filtered air (5-50 μm) with optional auto-switch for position feedback.
- Automated packaging line pusher mechanisms
- Plastic injection molding machine ejectors
- CNC machine tool clamping systems
- Agricultural equipment actuator for seed dispensers
- Automotive assembly line door panel pressing
