About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX700-75
The AirTAC SAIJ100X700-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 700 mm nominal stroke that can be fine-tuned down by up to 75 mm, yielding a precise 625-700 mm usable travel window. Equipped with a SUS304 stainless steel rod, it handles heavy loads with a push force of 7068 N at 0.9 MPa.
This adjustable-stroke design allows you to dial in the retract end-position during commissioning or product changeovers without adding external stops. The PT tapered port threads ensure a tight, leak-free pneumatic connection. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX700-75 Is Used
Variable End-Stop Positioning
Fine-tune the retract position within the 625-700 mm window to accommodate varying material lengths without physically swapping the cylinder.
Product Size Changeover
Quickly adjust the stroke by up to 75 mm during line changeovers to handle different product dimensions on the same conveyor setup.
Heavy-Duty Machine Setup
Leverage the 7068 N push force at 0.9 MPa for heavy clamping or pressing tasks while dialing in the exact end-of-stroke position at commissioning.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX700-75 the Right Cylinder?
Choose this 100 mm bore when your application requires substantial thrust, such as the 7068 N push force at 0.9 MPa, but still needs position flexibility. If you need less force, stepping down to an 80 mm bore yields 4523 N at 0.9 MPa. Because this cylinder features a 700 mm stroke, the 25 mm rod diameter requires an external guide to prevent excessive side-loading on the piston.
The rear adjuster acts purely as a travel stop and does not lock the load without live air. For load-holding requirements without continuous pneumatic pressure, consider an AirTAC SAIL or BSAI cylinder, or use an external pilot-operated check valve. This model is dimensionally interchangeable per ISO 15552 mounting interfaces.
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 SAIJ100BX700-75 FAQ
At an operating pressure of 0.9 MPa, this 100 mm bore cylinder provides a push force of 7068 N and a pull force of 3681 N. At 0.5 MPa, the push force is 3927 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 75 mm from the 700 mm nominal length, creating a 625-700 mm travel window. It functions as a mechanical stop for end-position tuning and is not a lock.
