About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX185-30S
The AirTAC SAIJ100X185-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 155-185 mm usable travel window, letting you dial back the 185 mm nominal stroke by up to 30 mm during commissioning. This variant features a SUS420J2 stainless steel rod and a built-in magnet for position sensing.
The rear adjuster acts purely as a mechanical stop to fine-tune the end position and is not a locking device. For load-holding without live air pressure, consider the SAIL or BSAI series. This profile cylinder supports mounting options Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. The integrated magnet works seamlessly with AirTAC CMSE reed and DMSE electronic sensors.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX185-30S Is Used
Machine Setup & Changeover
Fine-tune the 155-185 mm travel window during product line changeovers without disassembling the cylinder or bolting on external stops.
Variable End-Stop Positioning
Dial in the exact retract position for multi-format packaging lines, using the rear adjuster to trim the stroke by up to 30 mm.
Assembly Press Fine-Tuning
Adjust the pressing depth on the fly during commissioning to ensure precise force application without changing the fixed stroke length.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX185-30S the Right Cylinder?
Choose this 100 mm bore when an 80 mm bore (3518 N at 0.7 MPa) lacks sufficient thrust, but a 125 mm bore (8590 N at 0.7 MPa) is excessive. The adjustable stroke is ideal for product changeovers where exact end-of-stroke positioning varies slightly, saving you from swapping out a fixed-stroke SAI cylinder or adding external stops. Because the stroke is under 300 mm, side-load stress is minimal, though the robust 25 mm rod and M20x1.5 thread handle standard loads well. To match this ISO 15552 footprint, specify a 100 mm bore, 185 mm stroke, 30 mm adjustment, PT tapered G1/2 ports, and a -S magnet.
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 SAIJ100AX185-30S FAQ
The rear adjuster allows you to shorten the 185 mm nominal stroke by up to 30 mm, creating a 155-185 mm usable travel window. The adjuster acts as a mechanical stop to set the end position and is not a lock.
