Ultra-compact square body design optimized for space-constrained automation applications. Features corrosion-resistant construction with precision ground rod and dual guide bushings for enhanced lateral load capacity. The spring-return mechanism ensures fail-safe retraction during pressure loss. Requires 40μm filtered air supply with ISO 8573-1:2010 class 4.4.3 air quality.
- PCB handling robots in electronics assembly
- Precision clamping mechanisms in CNC tool changers
- Medical device actuation systems
- Textile machinery thread control
- Semiconductor wafer processing equipment
Installation note:
Mounting orientation affects performance - vertical installation requires spring chamber downward.
Allow 5mm clearance around cylinder body for heat dissipation. Lubricate rod weekly with ISO VG32 hydraulic oil
in high-cycle applications (>500,000 cycles/month).
