About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX180-10
The AirTAC SAIJ100X180-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 180 mm travel by up to 10 mm. This creates a precise 170-180 mm usable travel window, enabling fine end-position tuning at commissioning without swapping the cylinder or adding external stops. It delivers a robust 7068 N push force at 0.9 MPa, making it suitable for heavy-duty positioning.
This SKU features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic solid-state switches. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR configurations.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX180-10 Is Used
Machine Setup and Changeover
Fine-tune the 170-180 mm travel window during product size changeovers without physically swapping cylinders or repositioning hard stops.
End-Position Calibration
Use the 10 mm rear adjustment screw to dial in the exact retraction point during commissioning, compensating for mechanical tolerances.
Heavy-Duty Positioning
Leverage the 7068 N push force at 0.9 MPa to move and position heavy jigs or fixtures along the production line with precision.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX180-10 the Right Cylinder?
Choose this 100 mm bore when your application requires substantial thrust, such as the 5497 N push force available at 0.7 MPa. If your force requirements are lower, stepping down to an 80 mm bore yields 4523 N at 0.9 MPa, while moving up to a 125 mm bore provides 11045 N at 0.9 MPa. The adjustable stroke is ideal for machine setups requiring variable end stops or product-size changeovers, offering flexibility that a fixed-stroke SAI cylinder cannot match.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 180 mm stroke, 10 mm adjustment, PT port thread, and the specified mounting interface. Note that this unit lacks a magnet (-S), so position sensing requires adding a magnet or external sensors. For any stroke of 300 mm or more, an external guide is recommended to manage side loads, though this 180 mm stroke is well within standard limits. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for load-holding without pressure, consider an SAIL or BSAI cylinder.
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 SAIJ100AX180-10 FAQ
At an operating pressure of 0.9 MPa, this 100 mm bore cylinder provides a push force of 7068 N and a pull force of 3681 N. At 0.5 MPa, the push force is 3927 N.
The rear adjuster acts as a stopper that allows you to shorten the effective stroke by up to 10 mm from the nominal 180 mm, providing a usable travel window of 170-180 mm. It only sets the travel end and does not lock the load without live air pressure.
