About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX90-20
The AirTAC SAIJ32X200-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel window from 70 to 90 mm. It delivers 402N of push force and 345N of pull force at 0.5 MPa, making it well-suited for compact, low-weight actuation tasks.
This variant features a SUS304 stainless steel rod and PT tapered ports. The rear adjustment screw acts purely as a mechanical stop to set the retract end-position, meaning it will not hold the load dynamically without live air pressure. For position-holding requirements without continuous air, consider the SAIL or BSAI series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX90-20 Is Used
End-Stop Calibration
Dial in the exact 70-90 mm travel window during machine commissioning to perfect positioning without swapping out the physical cylinder.
Product Changeovers
Quickly adjust the retract distance on packaging lines when running slightly shorter product lengths, minimizing downtime between batches.
Lab Test Actuators
Leverage the SUS304 rod and variable 20mm stroke adjustment for sterile or corrosive testing environments requiring precise travel limits.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX90-20 the Right Cylinder?
Choose this 32mm bore when your application requires a 70-90 mm travel window and you need to dial in the exact end-stop during commissioning without adding external stops. If your setup needs higher force, stepping up to the 40mm bore yields a 528N pull force at 0.5 MPa. Because this is an ISO 15552 profile cylinder, it is dimensionally interchangeable with comparable standard profiles. To match this exact configuration, specify the 32mm bore, 90mm nominal stroke, 20mm adjustment, PT port thread, and SUS304 (B) rod material.
Since the nominal stroke is 90 mm, an external guide is not strictly required for side-load management, but the 12mm rod and M10x1.25 thread handle moderate bending loads well. Remember that the SAIJ mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.

- ✓ 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 SAIJ32BX90-20 FAQ
The rear adjuster screw mechanically stops the piston to shorten the nominal 90mm stroke by up to 20mm, giving an effective travel range of 70-90mm. It functions as a travel stop 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. At the maximum 1.0 MPa pressure, it can output up to 82 kgf.
