About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX275-40
The AirTAC SAIJ32X275-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 235 to 275 mm, allowing you to dial in the exact end position during commissioning without swapping out the unit. In the 32 mm bore class, it delivers 402 N of push force at 0.5 MPa and up to 724 N at 0.9 MPa.
This model uses an SUS420J2 stainless steel rod for enhanced corrosion resistance and features PT tapered port threads. The rear adjustment screw acts purely as a mechanical stop to set the travel limit; it does not lock the load. For position holding without live air pressure, consider the SAIL or BSAI series instead.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX275-40 Is Used
Commissioning Fine-Tuning
Dial in the exact 235 to 275 mm end position during machine setup without machining external stop blocks.
Product Size Changeover
Quickly adapt the cylinder's effective stroke on packaging lines when handling different product lengths.
Adjustable End-Stop
Use the rear screw to set a precise travel limit for delicate positioning tasks within the 40 mm window.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX275-40 the Right Cylinder?
Choose this 32 mm bore adjustable cylinder when your application requires precise end-position tuning or frequent product-size changeovers, stepping up from a smaller unit to gain 402 N of thrust at 0.5 MPa. If your force requirements are higher, moving to a 40 mm bore increases that output to 628 N. The adjustable stroke is ideal for setups where a fixed-stroke SAI cylinder would require external stop blocks to achieve the exact same variable end-stop.
Because this 275 mm stroke approaches the upper limits for this bore size, the 12 mm rod and M10x1.25 rod thread should be guided externally if the load is heavy or subject to lateral stress. It supports the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and is dimensionally interchangeable per ISO 15552. Note that without a magnet (-S), it cannot host CMSE or DMSE sensors.
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 SAIJ32AX275-40 FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 40 mm, providing a usable travel window of 235 to 275 mm. It acts as a mechanical stop and does not hold the load without live air pressure.
At 0.5 MPa it provides 402 N of push force and 345 N of pull force. At 0.9 MPa, the push force increases to 724 N.
