About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X290-75
The AirTAC SAIJ100X290-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers 3927N of push force at 0.5MPa and provides a usable travel window of 215-290mm, letting you trim the effective stroke by up to 75mm without swapping hardware. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
Equipped with a 25mm carbon steel rod and an M20x1.5 thread, this unit handles robust loads, though a 290mm stroke warrants an external guide to prevent excessive side-loading. The rear stopper acts purely as a travel end-setter for product changeovers, not as a load-holding lock; maintaining position requires continuous live air.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X290-75 Is Used
Variable End-Stop Tuning
Dial in the retract position precisely within the 215-290mm window during machine commissioning to accommodate different product lengths without external stopper blocks.
Product Changeover Systems
Rapidly adjust the stroke end-position on packaging lines when switching between box sizes, leveraging the 75mm trim range to maintain precise indexing.
Heavy-Duty Positioning
Utilize the 3927N push force at 0.5MPa to move heavy pallets or fixtures, relying on the 25mm carbon steel rod for structural stability under high load.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X290-75 the Right Cylinder?
Choose this 100mm bore when an 80mm cylinder (2513N push at 0.5MPa) lacks thrust, but a 125mm bore (6136N) would be excessive. The 75mm adjustment window is ideal for machines processing varying product sizes, allowing operators to dial in the exact retract position during commissioning rather than machining custom spacers.
For a direct ISO 15552 replacement match, specify a 100mm bore, 290mm stroke, 75mm adjustment, PT tapered port thread, and your required mounting style from the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, or TCM2. Because this model lacks a magnet (-S), it cannot host CMSE or DMSE sensors without a configuration change.
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 SAIJ100X290-75 FAQ
At 0.5MPa it provides 3927N of push force and 3681N of pull force. If you need higher thrust, increasing pressure to 0.7MPa yields 5497N of push force.
The rear adjuster screw lets you shorten the 290mm nominal stroke by up to 75mm, creating a usable travel window of 215-290mm. It acts as a mechanical stop to fine-tune the end position and is not a lock, so continuous air pressure is required to hold the load.
