About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X115-30
The AirTAC SAIJ32X115-30 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 115 mm stroke that can be fine-tuned down by up to 30 mm, creating an exact 85-115 mm usable travel window for precise commissioning. In the compact 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This adjustable model utilizes a PT tapered port thread and a 12 mm carbon steel rod. Unlike fixed-stroke actuators, the integrated rear stopper screw allows you to dial in the retract end position without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if a magnet is added later.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X115-30 Is Used
End-Stop Calibration
Dial in the exact retract position within the 85-115 mm window during machine commissioning without swapping out the entire cylinder.
Product Changeover
Quickly adjust the stroke by up to 30 mm on a packaging line when transitioning to a different product size or thickness.
Fixture Positioning
Set precise mechanical stops for clamping fixtures where pneumatic force up to 402 N is required but material thickness varies slightly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X115-30 the Right Cylinder?
Choose this 32 mm bore actuator when an application demands 402 N of thrust at 0.5 MPa but requires variable end-stop positioning within an 85-115 mm window. If your setup needs less force, stepping down is not an option below 32 mm, but if you need significantly more pull force for heavier tooling, the 40 mm bore provides 528 N of pull force at 0.5 MPa. The rear adjuster acts purely as a travel stop and does not lock the load; for true load-holding without live air pressure, consider an AirTAC SAIL or BSAI cylinder.
To match this ISO 15552 dimensionally interchangeable cylinder, confirm your requirements for a 115 mm stroke, 30 mm adjustment range, PT G1/8 port, and standard carbon steel rod. Because the stroke is under 300 mm, side-load stress on the 12 mm rod thread is minimal, though external guides are always recommended for optimal seal longevity. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

- ✓ 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 SAIJ32X115-30 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 a maximum 1.0 MPa, it can deliver up to 82 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from the 115 mm nominal stroke down to as little as 85 mm. It only sets the end position and does not hold the load without continuous air pressure.
