QGSJ Model Pneumatic Air Cylinder with 800mm Maximum Stroke and Bidirectional Braking

I. Features

1. This series is a derivative of the 10A-5 series cylinders, with many parts interchangeable.
2. Adopts aluminum alloy cylinder barrel and end caps, with an attractive appearance and light weight.
3. Can achieve locking and stopping at any position in the middle of the stroke, with high repeatability.
4. Uses a reasonable locking mechanism; the locking force is independent of the piston movement direction, ensuring reliable locking.
5. Oil-free (oil-lubricated optional) lubrication avoids oil-gas contamination, and the oil mist lubricator can be omitted.
