The PSB12X20SU features a space-saving cylindrical design with 30% reduced footprint compared to standard cylinders. Its precision-ground rod and dual sealing system ensure leak-free operation even in high-cycling applications (up to 3 million cycles). The cylinder body incorporates anti-rotation grooves for stable linear motion, making it ideal for vertical installations.
- PCB board clamping in SMT machinery
- Precision dosing valves in pharmaceutical equipment
- Micro-part ejection systems in watch manufacturing
- Optical lens positioning stages
- Laboratory sample handling robots
Installation note:
For vertical downward thrust applications, add a 0.3MPa minimum pressure margin above calculated requirements.
Use locknuts (not included) with 1.2–1.5Nm torque for mounting. Lubricate rod every 500,000 cycles using ISO VG32 hydraulic oil.
