Piston Rod Air Pneumatic Cylinders Festo Type ISO6432 DSNU pneumatic mini cylinder, bore 8-40mm
Pneumatic cylinders are commonly referred to as an Air cylinder, they provide motion and force to industrial and automation applications. Our range of Pneumatic cylinders create linear motion using a collection of pistons.
In contrast to a standard Single-acting Pneumatic cylinder, a Double-acting Pneumatic cylinder uses the output force in both forward and backward motion. This is done through the use of both the air exhaust and air pressure valves, these valves use compressed air to push the piston road in both directions.
Product Feature
1. The excellent running performance and long service life.
2. Self-adjusting pneumatic end-position cushioning saves time during commissioning and adapts optimally to load and speed changes.
3. Piston rod with internal or external thread.
4. Magnetic piston for position sensing.
5. A wide range of variants for customized applications, for example, smooth running, corrosion, or chemical resistance are required.
