About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X275-75
The AirTAC SAIJ100X275-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers a robust 3927N push force at 0.5 MPa, scaling up to 7068N at 0.9 MPa. By turning the rear stopper screw, you can trim the nominal 275mm travel back by up to 75mm, creating a precise 200-275mm usable window for exact end-position tuning during commissioning.
This 100mm bore unit uses a G1/2 PT port and a 25mm carbon steel rod with an M20x1.5 thread, providing high rigidity against side loads. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed and DMSE electronic switches. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X275-75 Is Used
Machine Changeovers
Dial in the 200-275mm travel window during product size transitions without swapping out the entire cylinder assembly.
Commissioning Calibration
Fine-tune the retract end position precisely at startup to avoid mechanical hard stops and reduce impact shock.
Variable End Stops
Set custom retraction depths for flexible manufacturing lines that process multiple part lengths on the same tooling.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X275-75 the Right Cylinder?
Select this 100mm bore model when an application requires substantial thrust (3927N at 0.5 MPa) alongside variable end-stop positioning. If you need less force, the 80mm bore offers 2513N at 0.5 MPa, whereas stepping up to the 125mm bore yields 6136N. The adjustable 200-275mm window is perfect for machine changeovers, eliminating the need to physically swap cylinders or bolt on external stops.
Because the stroke is 275mm, ensure adequate external guiding to prevent rod side-loading damage. Remember that the rear adjuster acts only as a travel stop, not a lock; the SAIJ does not hold its position without live air. For load-holding without pressure, consider SAIL or BSAI cylinders. To match this ISO 15552 interchangeable cylinder, specify: 100mm bore, 275mm stroke, 75mm adjustment, G1/2 PT port, required mounting, and no magnet.
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 SAIJ100X275-75 FAQ
The rear stopper screw lets you shorten the 275mm nominal stroke by up to 75mm, providing a usable travel window of 200-275mm. It acts as a mechanical stop to set the end position and does not lock the load without live air pressure.
At 0.5 MPa operating pressure, it provides 3927N of push force and 3681N of pull force. At the maximum 1.0 MPa pressure, the push force reaches 801 kgf.
