About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X30-20S
The AirTAC SAIJ100X30-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 3927N push force at 0.5 MPa and uses a 25mm carbon steel rod with M20x1.5 threading. The built-in rear stopper allows you to fine-tune the end position, creating a usable travel window between 10 and 30 mm without adding external stops.
This adjustable-stroke design is ideal for product changeovers where exact positioning varies slightly. The extruded aluminum barrel includes sensor grooves on both sides, and the -S magnet integrates directly with AirTAC CMSE reed and DMSE electronic switches. It supports PT porting and offers variable air cushions at both ends to decelerate the load smoothly.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X30-20S Is Used
Product Changeover
Dial in the 10-30mm travel window during format size changes on the line without physically swapping out the cylinder or adding external mechanical stops.
End-Stop Tuning
Fine-tune the exact retract position at commissioning using the rear screw, perfect for aligning heavy 3927N press or lift assemblies.
Short-Stroke Clamping
Provide robust clamping force on varied thickness parts by adjusting the effective stroke back by up to 20mm to accommodate different material sizes.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X30-20S the Right Cylinder?
Choose this 100mm bore when your application requires the 3927N push force at 0.5 MPa, stepping up from a 63mm bore that provides 1559N. The 20mm adjustment range is selected over a fixed SAI cylinder when you need to dial in the retract end-position during commissioning. Because the stroke is short at 30mm, side-load risks are minimal, but the 25mm rod thread handles robust mounting. The rear adjuster acts strictly as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider an external rod lock or the SAIL cylinder series.
To match this ISO 15552 replacement exactly, specify the 100mm bore, 30mm nominal stroke, 20mm adjustment, PT tapered port thread, and the -S magnet option. Mounting options are limited to the SAIJ set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ100X30-20S FAQ
At 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. It can reach a maximum push force of 7068N at 0.9 MPa.
The rear adjuster screw lets you shorten the 30mm nominal stroke by up to 20mm, providing a usable travel window of 10-30mm. It functions as a travel stop to fine-tune the end position and requires live air to hold the load.
