About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X35-30
The AirTAC SAIJ100X35-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 3927N push force at 0.5MPa and uses a G1/2 port. By turning the rear screw, you can shorten the effective travel from its 35mm nominal length down to a 5mm minimum, creating a 5-35mm usable window for precise end-position tuning.
This 100mm bore unit incorporates a carbon steel piston rod and variable air cushions at both ends to decelerate the load. The extruded aluminum barrel includes sensor grooves on both sides for fitting CMSE reed or DMSE electronic switches. It supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB and CA variants found on fixed-stroke counterparts.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X35-30 Is Used
Precision End-Stop Tuning
Dial in the exact clamping position on machining fixtures by adjusting the rear screw, trimming the 35mm stroke down to a 5mm minimum to accommodate varying part tolerances.
Product Changeover
Rapidly adapt automated lines to new package sizes by turning the rear stopper, shifting the effective travel window within the 5-35mm range without swapping the cylinder.
Assembly Actuation
Drive heavy pressing and joining operations with 3927N of push force at 0.5MPa, utilizing the built-in air cushions to decelerate the motion smoothly at the end of travel.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X35-30 the Right Cylinder?
Choose this adjustable-stroke model when an application requires exact end-position calibration during commissioning or product changeover without adding external stops. If you need less force, stepping down to an 80mm bore yields 2513N at 0.5MPa. The 25mm rod and M20x1.5 thread handle high side loads, but for any stroke of 300mm or more, an external guide is recommended to prevent rod deflection.
The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure. For load-holding requirements without continuous air, select a SAIL pneumatic lock, a BSAI clamp-lock cylinder, or an external rod lock. To replace an ISO 15552 cylinder, match the 100mm bore, 35mm stroke, 30mm adjustment, G1/2 port, PT thread, and mounting hardware.
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 SAIJ100X35-30 FAQ
At 0.5MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At the maximum 1.0MPa pressure, it delivers up to 801kgf.
The rear adjusting screw acts as a mechanical stop that lets you shorten the 35mm nominal stroke by up to 30mm. This creates a 5-35mm usable travel window for fine-tuning end positions without altering the cylinder mount.
