Ultra-compact pneumatic cylinder designed for space-constrained linear motion applications. Features a corrosion-resistant anodized aluminum barrel and precision ground piston rod for smooth operation. The spring-return mechanism provides reliable position recovery with ≤0.5mm repeat positioning accuracy. Requires 5μm filtered air and ISO VG32 turbine oil lubrication (optional oil-free operation).
- Precision part clamping in CNC fixtures
- Micro-dosing valve actuation in medical devices
- Paper feed mechanisms in office automation equipment
- Optical component positioning in semiconductor inspection
- Modular robotic gripper systems
Installation note:
Maintain 0.5-1mm alignment tolerance during mounting. For vertical installations,
use speed controller (ASC-06 recommended) to prevent piston overstroke. Lubricate
rod weekly in high-cycle applications (>500,000 cycles/month).
