About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X700-30S
The AirTAC SAIJ100X700-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a 670 to 700 mm usable travel window. Operating on filtered air, it delivers a robust 3927 N of push force at 0.5 MPa and reaches a maximum of 801 kgf at 1.0 MPa. The extruded aluminum barrel features sensor grooves on both sides to accommodate position feedback.
This model includes a standard magnet (-S) for use with AirTAC CMSE reed and DMSE electronic solid-state switches. The 25 mm carbon steel rod and M20x1.5 thread provide strong resistance to side loads, while the variable air cushions at both ends decelerate the motion. The rear stopper sets the travel end without locking the load, meaning live air pressure is required to hold position.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X700-30S Is Used
Machine Changeover
Dial in the exact 670 to 700 mm end-stop during product size changes on a packaging line without replacing the actuator.
Assembly Presses
Fine-tune the retraction end position during commissioning to apply precise clamping force using the 3927 N push capacity at 0.5 MPa.
Material Handling
Adjust the travel limit on long-stroke conveyors to accommodate varying package lengths while maintaining ISO 15552 mounting interchangeability.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X700-30S the Right Cylinder?
Choose this adjustable-stroke cylinder when your machine setup requires fine end-position tuning at commissioning or during product changeover without swapping out the entire actuator or adding external stops. If your application requires less force, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa; if more force is needed, a 125 mm bore provides 6136 N at 0.5 MPa. Because the nominal stroke is 700 mm, an external guide is recommended to prevent rod sagging and handle side loads over this long unsupported travel. For load-holding without continuous air pressure, select a SAIL or BSAI cylinder instead of relying on this rear stopper. This unit uses a PT tapered G1/2 port and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
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 SAIJ100 Adjustable Cylinder SAIJ100X700-30S FAQ
The rear adjuster screw acts as a mechanical stop that lets you trim the effective travel back by up to 30 mm, creating a 670 to 700 mm usable window. It sets the end position but does not lock the load without live air pressure.
It provides 3927 N of push force at 0.5 MPa and up to 801 kgf at 1.0 MPa. The standard operating speed range is 30 to 800 mm/s, regulated by the G1/2 port and adjustable air cushions at both ends.
