About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX275-100
The AirTAC SAIJ32X275-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits a usable travel window of 175 to 275 mm. Delivering 402 N of push force at 0.5 MPa, it suits light-duty positioning tasks. The piston rod is manufactured from SUS304 stainless steel, providing enhanced corrosion resistance for demanding environments.
This model uses PT tapered ports sized G1/8 and achieves a maximum standard stroke of 1000 mm. The rear adjustment mechanism acts strictly as a travel stop for end-position tuning during commissioning; it does not lock the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX275-100 Is Used
Variable End-Stop Positioning
Dial in the exact retract distance between 175 and 275 mm for precise component placement without swapping out the entire actuator.
Product Size Changeover
Quickly adapt machinery stops on a packaging line to accommodate varying package lengths during production transitions.
Machine Setup Commissioning
Fine-tune the travel end during initial machine commissioning to perfect timing and avoid mechanical interference.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX275-100 the Right Cylinder?
Select this 32 mm bore cylinder when an application requires fine-tuning of the retract end-position across a 175-275 mm window without adding external stops. If your process demands greater thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. Because this unit lacks a magnet, position sensing via CMSE or DMSE switches is not supported.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 275 mm stroke, 100 mm adjustment range, PT G1/8 ports, and SUS304 rod material. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR styles. Given the 275 mm stroke length, ensure adequate external guiding to prevent excessive rod side-loading.
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 Adjustable Cylinder SAIJ32 SAIJ32BX275-100 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 82 kgf.
The nominal stroke is 275 mm with a 100 mm adjustment code, creating an adjustable travel window from 175 to 275 mm. The rear adjuster functions as a stop for end-position tuning and does not hold the load without continuous air pressure.
