High-precision long-stroke cylinder featuring corrosion-resistant construction and smooth operation. The integrated hydraulic cushioning system reduces impact noise by 40% compared to standard models. Dual guide rods ensure straight-line accuracy (±0.1mm/m) for precision positioning tasks. Compatible with AirTAC's SNS/SND series sensors for position feedback.
- Automated assembly line material transfer systems
- Plastic injection molding machine ejectors
- Automotive welding fixture positioning
- Paper converting equipment actuators
- Heavy-duty stamping press auxiliary mechanisms
Installation note:
Requires alignment tolerance ≤0.2mm/m. For vertical mounting,
use supported guide mechanism. Lubricate rod weekly with ISO VG32
hydraulic oil in high-cycled applications. Maintain air filtration
at 25μm or finer.
Max side load: 150N.
For eccentric loads exceeding 50N, specify reinforced rod end
(SRE-40 option). Not recommended for continuous duty cycles
above 80% without cooling jacket.
