Copper-free stainless steel construction prevents catalytic reactions in oxygen-rich or medical environments. Features anti-rotation piston rod (keyway design) and hardened chromium-plated shaft (HRC 45-50). Includes built-in magnetic sensor slots (non-inductive type) for position feedback. Requires 5μm filtered air with ISO 8573-1:2010 Class 3.4.2 air quality.
- Semiconductor wafer handling systems (cleanroom compatible)
- Pharmaceutical blister packaging machines
- Marine equipment actuators (saltwater resistant)
- High-temperature food processing lines
- MRI-adjacent medical devices (non-magnetic design)
Installation protocol:
Use PTFE-based lubricant for assembly. Maintain 0.3-0.5mm radial clearance
during alignment. For stroke adjustment, limit cushion needle turns to 2.5
rotations max. Requires weekly lubrication in high-cycle applications (>500k cycles/month).
