Ultra-compact square-body cylinder optimized for space-constrained automation systems. Features corrosion-resistant construction with dual dust wipers for enhanced particle protection. The precision-ground rod and optimized air passage design enable smooth operation at speeds up to 1.5m/s. Requires 40μm filtered lubricated air (ISO 8573-1 class 4.4.3).
- PCB handling robots in electronics assembly
- Precision clamping mechanisms for CNC fixtures
- Medical device actuation systems
- Photovoltaic panel positioning devices
- Automated test equipment (ATE) actuators
Installation guidelines:
Mount using M4 screws (8.8 grade minimum) with 0.7-1.0Nm torque.
Maintain ≥5mm clearance around cylinder body for heat dissipation.
For vertical mounting, install air port upward to prevent condensate accumulation.
