A robust mid-sized pneumatic cylinder featuring precision honed tubing and wear-resistant seals. The dual cushion design allows smooth deceleration at stroke ends, reducing impact noise below 75 dB(A). The hardened piston rod (HRC 45-50) withstands side loads up to 15% of maximum thrust. Requires ISO VG32 hydraulic oil lubrication if used in high-cycle applications (>500,000 cycles).
- Conveyor belt gate actuators in logistics systems
- Clamping mechanisms in CNC machining centers
- Ejection systems for 300-800 ton injection molding machines
- Automotive assembly line positioning devices
- Printing press paper feed mechanisms
Installation Guidelines:
Maintain 0.5mm minimum clearance between rod end and load during alignment.
For vertical mounting (rod facing down), use model with spring-return option.
Lubricate through air supply (oil mist type) at 1 drop/minute/10 L/min airflow.
