The SI50X125STC is a heavy-duty ISO-standard pneumatic cylinder featuring dual-cushion impact absorption and precision honed tubing. Its multi-layer sealing system ensures ≤0.5 mL/min internal leakage under 0.5 MPa. The chrome-plated rod (hardness HRC45-50) resists side loads up to 150N at full extension. Requires 40μm filtered air with recommended ISO VG32 lubricant.
- High-speed press ejection systems (800+ cycles/hour)
- Automated palletizing machine vertical actuators
- Plastic injection molding machine core-pulling mechanisms
- CNC fixture clamping with position feedback
- Conveyor gate control in food processing lines
Installation tip:
For vertical mounting, add 0.5-1mm lateral clearance to prevent rod binding.
Lubricate rod weekly in high-cycle (＞1M cycles/year) applications. Use locknuts
with 25-30N·m torque for flange mounts.
