Ultra-compact square-body cylinder optimized for space-constrained automation applications. Features dual cushioning system for smooth end-stroke deceleration and corrosion-resistant construction. The square mounting face allows direct clamping with integrated M3 threads for tool-free installation. Requires filtered air (5-40μm) with max particle content ≤0.1mg/m³.
- PCB handling robots in electronics assembly
- Medical device clamping mechanisms
- Semiconductor wafer positioning systems
- Packaging machine ejector pins
- Laboratory automation sample handlers
Installation tip:
Maintain 0.5-1mm clearance between rod end and load during alignment.
For vertical mounting, use spring-side down orientation to prevent
seal wear from piston self-weight.
