About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX290-30
The AirTAC SAIJ100X290-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers a robust 3927N of thrust at 0.5 MPa and provides a usable travel window of 260 to 290 mm, letting you dial in the exact end position during commissioning. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches.
Built for demanding environments, this configuration uses a SUS304 stainless steel rod (option B) for superior corrosion resistance and features PT tapered port threads. The rear adjuster acts purely as a mechanical stop to set the retract distance, working alongside the standard air cushions to decelerate the load. It does not lock the position without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX290-30 Is Used
Product Changeover Positioning
Quickly modify the effective travel down to 260mm during packaging line size changeovers without disassembling machine hardware.
Commissioning End-Stop Tuning
Dial in the exact retract distance within a 30mm window during machine setup to perfect the mating alignment of heavy 3927N assemblies.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod and 0.15-1.0 MPa operating range for reliable heavy-duty cycling in washdown manufacturing zones.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX290-30 the Right Cylinder?
Choose this 100mm bore actuator when you need heavy thrust up to 3927N at 0.5 MPa, stepping up from a 63mm bore that offers 1559N. The 30mm adjustment range is ideal for product-size changeovers on a line, allowing you to fine-tune the retract end-stop without swapping the cylinder or bolting on external stops. For load-holding without continuous air pressure, select the SAIL or BSAI series instead, as the SAIJ adjuster is only a travel stop.
When replacing an ISO 15552 cylinder, match the 100mm bore, 290mm stroke, 30mm adjustment, PT port threads, and the standard mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke is 290mm, ensure proper external guidance to prevent excessive side-loading on the 25mm rod, despite its robust M20x1.5 thread.
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 SAIJ100BX290-30 FAQ
The rear adjuster screw lets you mechanically shorten the nominal 290mm stroke by up to 30mm, providing an effective travel window of 260 to 290mm. It functions as a physical stop to set the end position and does not lock the load without live air pressure.
At 0.5 MPa, it provides 3927N of push force and 3681N of pull force. At 0.7 MPa, the push force increases to 5497N.
