Ultra-slim profile cylinder optimized for space-constrained automation systems. Features dual anti-rotation guide slots (180° apart) for precise linear motion control. The hard-anodized inner bore ensures wear resistance, while the chrome-plated rod resists corrosion in humid environments. Requires ISO VG32 hydraulic oil lubrication if used in high-cycle applications (>1 million cycles).
- PCB handling robots in electronics manufacturing
- Medical device clamping mechanisms
- Automated packaging machine ejectors
- Precision valve actuation systems
- 3D printer component positioning
Installation guidelines:
Maximum side load ≤15% of theoretical thrust. Use floating joints for angular misalignment >0.5°.
For vertical mounting, install with rod facing downward to prevent condensate ingress. Lubricate every
6 months under normal operation (3 months in high-humidity environments).
- STA-MB: Magnetic sensor kit (2 pcs)
- STA-AC: Auto switchable cushion
- STA-RC: Stainless steel rod cover (IP67 upgrade)
