High-precision linear blocking cylinder designed for precision positioning and workpiece clamping in confined spaces. Features dual-action control with integrated magnetic sensor slots (non-inductive model as standard). The TWQ series utilizes a unique T-slot guide mechanism for enhanced lateral load resistance, achieving 2x longer service life compared to conventional rodless cylinders. Requires 5μm filtered dry air with ISO VG32 turbine oil mist lubrication (1 drop/cycle recommended).
- PCB board positioning in SMT assembly lines
- Glass panel clamping for LCD manufacturing
- Precision part ejection in die-casting machines
- Carton box alignment in packaging systems
- Semiconductor wafer handling robots
Installation guidelines:
Maintain horizontal orientation tolerance within ±2°. Lubricate guide rails every 500km of travel.
Use shock absorbers when cycle rate exceeds 120cpm. Minimum 3mm clearance required for sensor cables.
