The compact design achieves 30% space savings compared to standard ISO cylinders while maintaining 20% higher thrust force through optimized pressure-bearing structure.
- Food processing machinery (NSF compliant)
- Pharmaceutical cleanroom automation
- Semiconductor wafer handling systems
- Marine equipment actuators
- High-temperature packaging lines
- Laboratory analytical instruments
Operational guidance:
Lubricate with ISO VG32 hydraulic oil or equivalent before initial use.
For vertical mounting, install with rod facing downward to prevent
particle accumulation. Maximum side load: ≤15% of theoretical thrust.
