Ultra-compact pneumatic cylinder engineered for precision linear motion in space-constrained applications. Features corrosion-resistant construction with precision-ground rod and low friction seals, delivering 2.5N thrust force at 0.5MPa. Requires filtered dry air (40μm filtration, ISO 8573-1:2010 Class 4.4.3).
- Medical device actuation mechanisms
- PCB component insertion machines
- Laboratory automation sample handlers
- Semiconductor manufacturing equipment
- Precision inspection gauging systems
- Photovoltaic panel assembly lines
Installation recommendation:
Lubricate with ISO VG32 turbine oil before initial operation. For vertical mounting,
maintain minimum 0.3MPa pressure to prevent rod sag. Replace seals after
3 million cycles or 6 months (whichever comes first) in continuous duty applications.
