A high-rigidity ISO-standard cylinder featuring corrosion-resistant construction and precision honed tube. The dual adjustable cushions minimize impact noise while maintaining positioning accuracy (±0.5mm repeatability). Optimized seal design ensures ≤0.5mm/sec low-speed stability, with IP65 protection against particulate ingress.
- Material handling systems (conveyor diverters, lift gates)
- Automotive assembly line tooling
- Packaging machine actuation (case erectors, sealing arms)
- Plastic injection molding ejectors
- Semiconductor wafer handling robots
Installation guidelines:
Maintain ≤0.1mm/m alignment tolerance during mounting. Use flexible couplings
when lateral forces exceed 15% of max thrust. For vertical installations,
specify "UP" marked models with reinforced rod locks.
