About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX700-30
The AirTAC SAIJ100X700-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 670 to 700 mm usable travel window, allowing you to dial back the retract end-position by up to 30 mm during commissioning. Delivering 3927 N of push force at 0.5 MPa, it handles heavy positioning tasks without needing external stops.
This model uses a SUS304 stainless steel rod for superior corrosion resistance. It features a G1/2 port and omits the FB, CA, CB and CR mounts, offering the standard SAIJ subset of Basic, FA, LB, TC, FTC, TCM1 and TCM2 attachments. The rear adjuster acts only as a travel stop, meaning it will not hold a load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX700-30 Is Used
Machine Setup Calibration
Dial in the exact 670 to 700 mm retract position during initial commissioning to align heavy tooling without adding external stopper blocks.
Product Size Changeover
Quickly adjust the end-stop up to 30 mm when switching the production line to a different product length, minimizing downtime.
Heavy Material Positioning
Leverage the 3927 N push force at 0.5 MPa to move heavy workpieces into machining stations with precise variable end positioning.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX700-30 the Right Cylinder?
Choose this 100 mm bore when 80 mm falls short (delivering 2513 N at 0.5 MPa) but 125 mm is excessive (6136 N). The 30 mm adjustment window is perfect for product changeovers, letting you fine-tune the end stop without swapping cylinders. For load-holding without live pressure, select a SAIL or BSAI cylinder instead.
At 700 mm, this stroke requires an external guide to prevent rod sag and side-load damage. To match this ISO 15552 cylinder, specify the 100 mm bore, 700 mm stroke, 30 mm adjust, PT G1/2 port, and your preferred mounting option.
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 SAIJ100BX700-30 FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw lets you shorten the 700 mm nominal stroke by up to 30 mm, creating a 670 to 700 mm travel window. It acts as a mechanical stop and does not lock the load without live air pressure.
