About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX115-20
The AirTAC SAIJ100X115-20 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 95-115 mm usable travel window, allowing you to trim the nominal 115 mm stroke by up to 20 mm during commissioning. Delivering 3927 N of push force at 0.5 MPa, it handles heavy-duty positioning with precision.
This variant features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and ships with PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. You can fine-tune the retract end-position without swapping the cylinder or adding external stops.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX115-20 Is Used
Product Changeovers
Dial in the 95-115 mm travel window on the fly to accommodate different product lengths on the same packaging line without changing hardware.
Commissioning Calibration
Fine-tune the retract end-position during initial machine setup to achieve precise alignment without machining custom external spacers.
Heavy Clamping Fixtures
Leverage the 3927 N push force at 0.5 MPa to secure heavy workpieces, using the adjustable stop to set the exact clamping depth.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX115-20 the Right Cylinder?
Choose this 100 mm bore when a 50 mm cylinder (982 N push at 0.5 MPa) lacks the thrust for your payload, but an 80 mm bore (2513 N) is borderline. The adjustable stroke is ideal for machine setups requiring variable end-stops or product-size changeovers, avoiding the need to stock multiple fixed-stroke SAI cylinders.
For ISO 15552 replacement matching, ensure you specify the 100 mm bore, 115 mm stroke, 20 mm adjustment, PT ports, and the SUS420J2 rod. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for fail-safe load holding, consider an external rod lock or the SAIL series. The M20x1.5 rod thread handles high side loads, but always support long strokes with an external guide.
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 SAIJ100AX115-20 FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from 115 mm down to 95 mm. It sets the travel end but is not a lock, meaning the cylinder requires live air to hold its position.
