Precision stroke-adjustable cylinder featuring a unique dual-locking mechanism for position retention. The SAUJ series incorporates a visible stroke scale (0-250mm marked every 5mm) and torque-controlled adjustment knob (3.5N·m max). Includes integrated magnetic sensor groove for position detection compatibility. Requires ISO 8573-1:2010 [4:4:3] class air quality.
- Variable height positioning in semiconductor wafer handling
- Pressure-sensitive assembly processes (e.g., smartphone screen pressing)
- Packaging line product ejection with force control
- Textile machinery thread tension adjustment systems
- Automated paint spray distance regulation
Installation protocol:
Locking mechanism requires manual release before adjustment - always depressurize system.
For vertical installations exceeding 45° angle, use rod-end support bracket (sold separately).
Lubricate with ISO VG32 turbine oil monthly under continuous operation.
