About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X900-30
The AirTAC SAIJ100X900-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 870-900 mm usable travel window, allowing you to dial back the 900 mm nominal stroke by up to 30 mm during machine commissioning. Delivering 7068 N of push force at 0.9 MPa, it is built to handle heavy loads with precision.
This model uses a 25 mm carbon steel rod with an M20x1.5 thread, offering robust resistance to side loads, though the 900 mm length still requires an external guide for stability. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X900-30 Is Used
Variable End-Stop Tuning
Fine-tune the retraction point within the 870-900 mm window to accommodate varying material thicknesses on the fly without mechanical rebuilds.
Machine Changeover
Speed up product line transitions by dialing in the exact 30 mm adjustment range at the rear screw, bypassing the need to swap out the entire cylinder.
Heavy Load Positioning
Leverage the 7068 N push force at 0.9 MPa to shift heavy pallets or assemblies, relying on the external guide to support the long 900 mm stroke.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X900-30 the Right Cylinder?
Choose this 100 mm bore when you need more thrust than the 80 mm version (which provides 4523 N at 0.9 MPa) but want to avoid the heavier 125 mm class. The adjustable stroke is ideal for product changeovers where the exact end-position varies slightly, saving you from swapping cylinders or adding external stops. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider the SAIL or BSAI series. To match an ISO 15552 replacement, verify the 900 mm stroke, 30 mm adjustment, PT G1/2 port, and your required mounting.
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 SAIJ100X900-30 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.
The rear adjuster screw allows you to shorten the effective travel from the 900 mm nominal stroke down to 870 mm. It functions purely as a mechanical stop to fine-tune the end position and does not lock the load without continuous air pressure.
