About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X750-30
The AirTAC SAIJ100X750-30 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 720-750 mm usable travel window, allowing you to dial back the nominal 750 mm stroke by up to 30 mm during commissioning. Delivering 3927 N of push force at 0.5 MPa, it handles heavy loads while utilizing a standard G1/2 port and M20x1.5 rod thread.
This extruded aluminum profile cylinder features sensor grooves on both sides for straightforward position feedback. Because the rear screw acts purely as a travel stop and not a lock, it relies on live air to maintain position; for dead-air load holding, consider an external rod lock or the SAIL series. The standard carbon steel rod and PT tapered port ensure robust, leak-free pneumatic connections.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X750-30 Is Used
Machine Changeover
Quickly reconfigure end-stops for different product lengths on a packaging line without disassembling the pneumatic circuit.
Press Positioning
Fine-tune the retraction point of a heavy press to accommodate varying material thicknesses during commissioning.
Diverting Mechanisms
Adjust the stroke of a diverter arm on a conveyor to handle multiple box sizes accurately on the fly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X750-30 the Right Cylinder?
Choose this 100 mm bore when a 63 mm cylinder (1559 N push at 0.5 MPa) is insufficient, but a 125 mm bore (6136 N) would be excessive overkill. The 30 mm adjustment range is ideal for product-size changeovers on a line, letting you fine-tune the end position without swapping cylinders or adding external stops. For a fixed end position, a standard SAI cylinder would suffice, but the SAIJ variant offers superior setup flexibility.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 750 mm stroke, 30 mm adjustment, G1/2 port, and mounting style. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR. Because the stroke is 750 mm, the M20x1.5 rod requires external guiding to prevent excessive side-loading on the long unsupported travel. Speed ranges from 30-800 mm/s.
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 SAIJ100X750-30 FAQ
At 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 allows you to shorten the effective stroke by up to 30 mm, creating a 720-750 mm travel window. This stopper fine-tunes the end position but does not lock the load without live air pressure.
