About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X30-30
The AirTAC SAIJ100X30-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. With a 30mm nominal stroke and a 30mm adjustment code, it provides a usable travel window of 0 to 30mm, allowing you to dial in the exact end position during commissioning without swapping hardware. It delivers a robust 3927N of push force at 0.5MPa, making it ideal for heavy-duty positioning.
This extruded aluminum profile barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches. The standard carbon steel piston rod features an M20x1.5 thread, and the unit omits the FB, CA, CB, and CR mounting styles, offering a focused set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 attachments.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X30-30 Is Used
End-Position Tuning
Fine-tune the retracted end position by up to 30mm during machine commissioning to achieve perfect alignment without adding external stops.
Product Changeover
Quickly adapt the stroke window for different product sizes on a packaging line, using the rear screw to set the exact travel limit.
Heavy-Duty Clamping
Leverage the 3927N push force at 0.5MPa for high-force clamping tasks where the exact contact position varies slightly per workpiece.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X30-30 the Right Cylinder?
Choose this 100mm bore cylinder when a 80mm bore (2513N push at 0.5MPa) is insufficient, or step down if the 125mm bore (6136N) is overkill. The adjustable stroke is selected over a fixed SAI cylinder when you need precise end-position tuning for variable product sizes or machine changeover. The rear adjuster acts purely 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.
For an exact ISO 15552 replacement, match the 100mm bore, 30mm stroke, PT tapered port thread, G1/2 port size, and standard carbon steel rod. Since the nominal stroke is only 30mm, side-load concerns are minimal, but always ensure the load is guided to prevent binding.
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 SAIJ100X30-30 FAQ
At 0.5MPa, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.9MPa, the push force increases to 7068N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from 30mm down to 0mm. It decelerates the end position but does not lock the load without live air pressure.
