About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X275-20
The AirTAC SAIJ100X275-20 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 255 to 275 mm, allowing you to dial back the nominal 275 mm stroke by up to 20 mm during commissioning. Delivering 3927 N of push force at 0.5 MPa, it handles heavy loads while maintaining a standard ISO 15552 mounting footprint.
The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if a magnet is added later. The carbon steel rod and M20x1.5 rod thread offer robust side-load resistance, while the rear stopper functions strictly as a travel end-deceleration point, not a load-holding lock. For position holding without live air, consider an external rod lock or the related SAIL series.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X275-20 Is Used
Product Changeover Tuning
Dial in the 255-275 mm travel window during line changeovers to accommodate different package sizes without replacing the cylinder.
End-Stop Calibration
Fine-tune the final retract position during machine setup, using the 20 mm rear adjustment to perfect tool alignment without external stoppers.
Heavy Forming Operations
Leverage the 3927 N push force at 0.5 MPa for pressing and forming tasks where exact end-of-stroke positioning must be dialed in on-site.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X275-20 the Right Cylinder?
Choose this 100 mm bore when 80 mm falls short (2513 N push at 0.5 MPa) and 125 mm is excessive (6136 N). The adjustable 255-275 mm travel is ideal for product changeovers, letting you fine-tune end positions without swapping cylinders or bolting on external stops. Because the 275 mm stroke is significant, always guide the load externally to prevent rod bending.
This model uses PT tapered ports and a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR. The rear adjuster and air cushions only decelerate the stroke; they do not hold the load without live air pressure. For true locking needs, select the BSAI clamp-lock or SAIL pneumatic lock variants.
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 SAIJ100X275-20 FAQ
At 0.5 MPa, it provides 3927 N of push force and 3681 N of pull force. At the maximum operating pressure of 1.0 MPa, the push force reaches 801 kgf.
The rear adjuster acts as a mechanical stop, allowing you to shorten the effective stroke from 275 mm down to 255 mm. This enables precise end-position tuning during commissioning without needing to swap the cylinder.
