About the Airtac SAI40 Standard Air Cylinder SAI40X600
The AirTAC SAI40X600 is a double-acting ISO 15552 profile cylinder engineered to deliver 879 N of push force at 0.7 MPa. Its 600 mm stroke provides the extended travel needed for material handling and automated positioning tasks. The extruded aluminum barrel design omits tie rods, ensuring a clean exterior that resists mechanical fouling.
This configuration utilizes a standard carbon steel piston rod and a PT tapered G1/4 port thread. Because a magnetic piston (-S) is not specified, position sensing via CMSE or DMSE switches is not enabled. For applications requiring heat resistance, the standard TPU seals can be swapped for Viton (H) to handle higher ambient temperatures.

Where the Airtac SAI40 Standard Air Cylinder SAI40X600 Is Used
Package Routing
Diverts packages along a 600 mm stroke path using 879 N of thrust at 0.7 MPa, ensuring reliable sorting in high-speed distribution centers.
Component Feeding
Pushes blanks into machining centers with a rigid carbon steel rod, handling the extended travel without requiring a larger bore size.
Pallet Handling
Actuates lifting mechanisms over a 600 mm distance, relying on adjustable air cushions to smoothly stop the payload at stroke end.
Is the Airtac SAI40 Standard Air Cylinder SAI40X600 the Right Cylinder?
Stepping up to the 50 mm bore increases the 0.5 MPa push force from 628 N to 982 N, while dropping down to a 32 mm bore reduces it to 402 N. Choose this 40 mm bore when your pneumatic system requires moderate thrust within the 30-800 mm/s operational speed range.
With a 600 mm stroke, the extended rod is highly susceptible to bending under side loads. Implement an external guide rail or select a guided cylinder to prevent premature rod-bearing wear. This standard double-acting cylinder relies on adjustable air cushions at both ends to decelerate the piston; it does not hold position if air pressure drops. Use the SAIL variant for pneumatic locking requirements. As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for any standard 40 mm bore, 600 mm stroke, G1/4 ported unit with compatible FA or LB mounting accessories.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAI40 Standard Air Cylinder SAI40X600 FAQ
The SAI40X600 generates 628 N of push force and 528 N of pull force at 0.5 MPa. At 0.7 MPa, the push force increases to 879 N.
Yes. The SAI40X600 is dimensionally interchangeable per ISO 15552. You can drop it in place of any 40 mm bore, 600 mm stroke ISO 15552 profile cylinder with a G1/4 port.
