A high-rigidity industrial cylinder featuring chrome-plated piston rod and precision honed aluminum barrel. The SI63X140S delivers 4.9kgf/cm² operating force with ±0.5mm repeat positioning accuracy. Integrated shock absorbers reduce end-impact noise by 15dB compared to basic models. Compatible with AirTAC's full range of magnetic sensors (D-A93 series recommended).
- Palletizing robot arm actuation
- Injection molding machine ejection systems
- CNC machine tool clamping mechanisms
- Automotive assembly line positioning
- Food processing conveyor gate control
Installation note:
Maintain 0.05mm/m alignment tolerance during mounting. Use flexible couplings when connecting to
guided mechanisms. Lubricate with ISO VG32 hydraulic oil if operating below 3℃. Cycle rate should
not exceed 80% of maximum rating for continuous duty applications.
- Replace rod wipers every 5 million cycles
- Inspect piston seal leakage every 2,000 operating hours
- Lubrication interval: 100km of cumulative stroke distance
