About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X700-30
The AirTAC SAIJ100X700-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 700 mm nominal travel by up to 30 mm for a precise 670-700 mm usable window. Built with a carbon steel rod and a G1/2 PT tapered port, it delivers 5497 N of push force at 0.7 MPa, making it suitable for heavy-duty positioning tasks.
This extruded aluminum profile cylinder features adjustable air cushions at both ends to manage kinetic energy, though the rear screw acts purely as a travel stop and does not hold the load without live air. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X700-30 Is Used
Machine Changeover
Quickly shift the retract end-stop by up to 30 mm when adapting a heavy-duty packaging line to a new product size.
End-Position Tuning
Fine-tune the 670-700 mm travel window during commissioning to achieve exact seating without mechanical shims.
Heavy Material Handling
Leverage the 5497 N push force at 0.7 MPa to move substantial pallets or fixtures along a long-stroke conveyor path.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X700-30 the Right Cylinder?
Choose this 100 mm bore when you need significantly more thrust than a 63 mm cylinder (which provides 2182 N push at 0.7 MPa) but want to avoid the bulk of a 125 mm unit. The adjustable stroke is ideal for fine-tuning the end position during commissioning or product changeovers without swapping the cylinder or adding external stops. For load-holding without continuous air pressure, consider a SAIL or BSAI cylinder instead, as this adjuster is not a lock.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 700 mm stroke, 30 mm adjustment, G1/2 port, and required mounting accessories. Because the 700 mm stroke is lengthy, the 25 mm rod and M20x1.5 thread still require an external guide to prevent excessive side-loading on the piston.
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 SAIJ100X700-30 FAQ
The rear adjuster screw acts as a mechanical stop that shortens the effective travel by up to 30 mm, providing a usable stroke window of 670 to 700 mm. It only sets the end position and does not lock the load without live air pressure.
At a 0.7 MPa operating pressure, the SAIJ100X700-30 provides 5497 N of push force and 3681 N of pull force. It can reach a maximum push force of 7068 N at 0.9 MPa.
