About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX110-30S
The AirTAC SAIJ100X110-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down to 80 mm from the 110 mm nominal stroke. Equipped with a SUS420J2 stainless steel rod and a position magnet, it generates 3927 N of push force and 3681 N of pull force at 0.5 MPa. The G1/2 PT tapered ports and integrated adjustable air cushions manage the kinetic energy of this heavy-duty actuator at cycle speeds up to 800 mm/s.
This adjustable-stroke design eliminates the need to swap cylinders or add external stops during machine commissioning or product changeover. The rear screw acts purely as a travel stop to set the retract end-position, meaning it does not hold the load without live air pressure. For load-holding requirements without continuous air, consider the SAIL or BSAI series, or use an external rod lock. The extruded aluminum barrel includes sensor grooves on both sides for precise tracking with CMSE reed or DMSE solid-state switches.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX110-30S Is Used
Machine Changeover
Quickly fine-tune the retract end-position within the 80-110 mm window when switching between product sizes on a packaging line, avoiding physical cylinder swaps.
Pressing & Forming
Leverage the 3927 N push force at 0.5 MPa for light pressing tasks, using the rear stopper to precisely set the forming depth without altering the pneumatic pressure.
End-Stop Calibration
Dial in exact retraction limits during initial machine commissioning, using the 30 mm adjustment range to compensate for mechanical tolerances in the fixture.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX110-30S the Right Cylinder?
Choose this 100 mm bore when an 80 mm bore (providing 2513 N push at 0.5 MPa) is insufficient for your clamping or pressing force, but a 125 mm bore is too bulky. The 30 mm adjustment window is perfect for dialing in exact end-of-stroke positions during setup. When specifying an ISO 15552 replacement, match the 100 mm bore, 110 mm stroke, 30 mm adjust, G1/2 PT ports, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Because the stroke is 110 mm, side-load is minimal, but always guide the load externally if heavy lateral forces are present.
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 SAIJ100AX110-30S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force. At the maximum 1.0 MPa pressure, the push force reaches 7068 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke from 110 mm down to as little as 80 mm. This allows precise end-position tuning at commissioning, but it is only a stop and does not lock or hold the load without live air pressure.
