The PSBR8X25U features a space-saving square head design with integrated mounting points, offering 25mm linear motion through compressed air activation and spring return. Its pen-type profile (71mm body length) enables installation in tight spaces while maintaining 8mm bore force output. The dual-port design allows flexible pneumatic circuit integration, with M5x0.8 threads supporting flow rates up to 35 L/min.
- Precision part clamping in SMT equipment
- Micro-positioning in semiconductor handlers
- Ejector mechanisms in compact automation cells
- Valve actuation in analytical instruments
- Paper feed control in desktop printers
Installation tip:
For optimal performance, maintain 0.3-0.5 MPa operating pressure and use 25μm filtered air.
The square head allows 90° rotation for flexible orientation. Lubricate rod every 500km stroke
in high-cycle applications (>1 million cycles).
