About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX130-75
The AirTAC SAIJ100X130-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 130 mm stroke that can be fine-tuned down by up to 75 mm, yielding a highly flexible 55-130 mm usable travel window for precise end-position calibration. Belonging to the 100 mm bore class, it delivers 3927 N of push force at 0.5 MPa and up to 7068 N at 0.9 MPa, making it a robust choice for heavy-duty positioning tasks.
This unit features a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance and a 25 mm rod diameter paired with an M20x1.5 thread to handle substantial side loads. The rear adjustment screw acts purely as a mechanical stop to set the retract end position during commissioning or product changeovers. It is not a locking device; the cylinder relies on live air to hold the load, and the double-ended air cushions manage deceleration without functioning as a brake.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX130-75 Is Used
Machine Changeover
Dial in the exact retract position within the 55-130 mm window during product size transitions without adding external mechanical stops.
Heavy Positioning
Leverage 7068 N of push force at 0.9 MPa to move heavy jigs into place, relying on the rear screw for final end-position tuning.
Assembly Station Setup
Fine-tune the stroke at commissioning to accommodate varying part dimensions, using the standard ISO 15552 footprint for straightforward integration.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX130-75 the Right Cylinder?
Choose this adjustable model over a fixed-stroke SAI cylinder when your machine setup requires variable end stops or frequent product-size changeovers without physically swapping the actuator. If your application demands less force, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa, whereas moving up to a 125 mm bore provides 6136 N. Because the 130 mm stroke is relatively short for this bore size, side-load risks are minimal, though an external guide is always recommended for heavy radial loads.
To match this ISO 15552 interchangeable cylinder for a replacement, verify the 100 mm bore, 130 mm nominal stroke, 75 mm adjustment range, PT tapered port thread (G1/2), and the specific mounting set. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, deliberately omitting FB, CA, CB, and CR. Note that this SKU lacks a magnet, so position sensing via CMSE or DMSE switches is not supported without a -S variant.
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 SAIJ100AX130-75 FAQ
At 0.5 MPa, it provides 3927 N of push force and 3681 N of pull force. At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 130 mm nominal stroke by up to 75 mm. This creates a 55-130 mm usable travel window for precise end-position tuning without replacing the cylinder.
