About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX290-10
The AirTAC SAIJ32X290-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 280-290 mm usable travel window from its 290 mm nominal stroke. Equipped with a SUS304 stainless steel rod and PT tapered ports, it delivers 402N of push force at 0.5 MPa. This bore size uses a 12 mm rod and M10x1.25 threading, operating at speeds between 30-800 mm/s.
Because the stroke reaches 290 mm, the 12 mm rod requires external guide support to prevent excessive side-loading on the front cap. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to add CMSE reed or DMSE electronic sensors later if position feedback becomes necessary. The rear adjuster acts purely as a travel stop for end-position tuning, not a load-holding lock.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX290-10 Is Used
Product Changeover
Dial in the 10 mm adjustment range to quickly accommodate slightly different product lengths on the line without changing the cylinder mounting.
Machine Setup
Fine-tune the retract end-position during initial commissioning, ensuring precise mechanical alignment without adding external stopper blocks.
Variable End Stops
Use the 280-290 mm travel window to set exact retraction depths for delicate positioning tasks in light assembly automation.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX290-10 the Right Cylinder?
Choose this 32 mm bore when your application requires the 402N push force at 0.5 MPa and benefits from a variable end-stop without swapping cylinders during product changeovers. If your setup demands greater thrust, stepping up to the 40 mm bore yields 628N of push force at the same pressure. The SAIJ configuration omits the FB, CA, CB, and CR mounting options, supporting only Basic, FA, LB, TC, FTC, TCM1, and TCM2 interfaces. For any load-holding requirements without live air pressure, this cylinder will not suffice; you must integrate an external pilot-operated check valve or select the SAIL or BSAI series instead.

- ✓ 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 Adjustable Cylinder SAIJ32 SAIJ32BX290-10 FAQ
The rear adjuster allows you to shorten the effective stroke by up to 10 mm, providing a usable travel window of 280-290 mm from the 290 mm nominal stroke. This stopper is designed for end-position tuning and does not lock or hold the load without live air pressure.
At 0.5 MPa operating pressure, it provides 402N of push force and 345N of pull force. The maximum thrust is 82 kgf at 1.0 MPa.
