About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-30
The AirTAC SAIJ32X100-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the effective travel anywhere within a 70 to 100 mm window. Built with a carbon steel piston rod and a PT tapered port, this 32 mm bore actuator delivers 402 N of push force at 0.5 MPa. It utilizes an extruded aluminum barrel rather than a tie-rod design, ensuring dimensionally interchangeable mounting per ISO 15552.
The integrated rear stopper screw lets you dial in the retract end-position during commissioning without adding external stops. Because this adjuster acts purely as a mechanical travel limit and works alongside the standard air cushions, it does not hold the load without live air pressure. For applications requiring position holding, consider the SAIL or BSAI series instead.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-30 Is Used
Machine Changeover
Quickly adjust the retract end-position within the 70-100 mm window to accommodate different product sizes without physically replacing the cylinder.
Commissioning Calibration
Fine-tune the final resting position during initial setup, using the rear stopper screw to perfect the mechanical alignment of small tooling.
Light Assembly Tooling
Provides 402 N of precise linear thrust at 0.5 MPa for small part pressing or positioning tasks where exact end-stops are critical.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-30 the Right Cylinder?
Choose this 32 mm bore when your application requires up to 402 N of push force at 0.5 MPa, or step up to the 40 mm bore if you need 628 N. The adjustable 30 mm window is ideal for product changeovers on a line, allowing you to vary the end-stop on the fly rather than swapping out a fixed-stroke SAI cylinder. To match this exact ISO 15552 replacement, verify your 100 mm stroke, the 30 mm adjustment requirement, PT port threads, and your preferred mounting style.
Supported mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR variants. Since this model lacks the -S suffix, it does not include a magnet for CMSE or DMSE sensors. The 12 mm rod and M10x1.25 thread provide adequate support for standard loads, though any long, unsupported stroke still requires external guiding.
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 SAIJ32X100-30 FAQ
At a 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach a maximum push force of 724 N at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the nominal 100 mm stroke by up to 30 mm. This creates a usable travel window of 70 to 100 mm. The adjuster only sets the travel end and does not lock the load without continuous air pressure.
