This ultra-compact cylinder combines space-saving design (40% thinner than standard models) with precision stroke adjustability through its innovative screw-lock mechanism. The anodized surface treatment provides enhanced corrosion resistance, while the dual guide rod structure ensures exceptional lateral load capacity (up to 30N·m). Features built-in magnet slots for sensor mounting and supports dual pneumatic connections for optimized airflow.
- PCB handling robots requiring precise component placement
- Pharmaceutical blister packaging machines
- Semiconductor wafer transfer systems
- Automated optical inspection (AOI) equipment
- Compact assembly stations in automotive electronics
Installation protocol:
Always use alignment jigs during mounting to prevent guide rod binding.
Requires 0.3μm filtered air with ISO 8573-1:2010 Class 2.4.2 standards.
Lubricate every 5 million cycles using ISO VG32 turbine oil.
Critical note:
Stroke adjustment must be performed in depressurized state.
Exceeding 90mm stroke may damage internal stopper mechanism.
Maximum side load: 15% of theoretical thrust at 0.6MPa.
