About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX115-30
The AirTAC SAIJ100X115-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the retract position during commissioning. By turning the external stopper screw, you can trim the nominal 115 mm stroke back by up to 30 mm, creating a usable travel window between 85 and 115 mm without adding external stops.
Delivering 3927 N of push force at 0.5 MPa, this 100 mm bore unit features a robust 25 mm carbon-steel rod with an M20x1.5 thread, paired with PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and the rod is built from corrosion-resistant SUS420J2 stainless steel (A) for demanding environments.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX115-30 Is Used
Machine Changeover
Dial in the exact retract distance on the fly when switching a production line to a new product size.
End-Position Tuning
Fine-tune the final resting position of tooling during commissioning without bolting on external stops.
Variable End Stops
Adjust the travel window between 85 and 115 mm to accommodate varying material thicknesses in automated assembly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX115-30 the Right Cylinder?
Choose this adjustable-stroke model when a machine setup requires variable end-stops or frequent product-size changeovers, avoiding the need to physically swap out a fixed-stroke SAI cylinder. If your application requires less force, stepping down to an 80 mm bore yields 2513 N of push thrust at 0.5 MPa.
Because the rear adjuster acts solely as a travel stop and the air cushions only manage deceleration, neither will hold a load securely without live air pressure. For true load-holding, consider an AirTAC SAIL or BSAI cylinder. To match this ISO 15552 footprint exactly, specify a 100 mm bore, 115 mm stroke, 30 mm adjustment, PT ports, and your required mounting interface.
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 SAIJ100AX115-30 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 the maximum rated pressure of 0.9 MPa, it delivers 7068 N of push force.
A rear-mounted stopper screw lets you shorten the nominal 115 mm stroke by up to 30 mm, providing an adjustable travel window of 85 to 115 mm. This allows precise end-position tuning without changing the cylinder.
