About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX35-30S
The AirTAC SAIJ32X35-30-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers 402 Newtons of pull force at 0.5 MPa and provides a usable travel window of 5 to 35 mm, letting you dial in the exact end position without swapping hardware. The barrel is extruded aluminum, and the rod is SUS304 stainless steel for superior corrosion resistance.
This variant includes a magnet for position sensing, working seamlessly with AirTAC CMSE reed and DMSE electronic switches fitted into the dual-side sensor grooves. The rear adjustment screw acts purely as a mechanical stop for end-position tuning; it does not lock or hold the load without continuous air pressure. For load-holding requirements, consider an external pilot-operated check valve or the related SAIL series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX35-30S Is Used
Changeover Calibration
Dial in the exact retract position within the 5-35mm window during machine format changes without replacing the cylinder.
End-Stop Tuning
Fine-tune the final resting position of a small actuator at commissioning, absorbing mechanical tolerance stacks directly at the rear stopper.
Variable Product Ejection
Adjust the ejection stroke on the fly for different product sizes on a conveyor line, using the rear screw to set the exact travel limit.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX35-30S the Right Cylinder?
Choose this 32mm bore when your application requires precise, variable end-stops during commissioning or product changeover, rather than a fixed-stroke SAI cylinder. If you need greater thrust, stepping up to the 40mm bore yields 528N of pull force at 0.5 MPa. Because this is a 35mm stroke, side-loading is minimal, but always guide the load to prevent rod binding.
To match this ISO 15552 interchangeable cylinder, specify a 32mm bore, 35mm nominal stroke, 30mm adjustment range, PT tapered port threads, and the -S magnet option. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Operating speed ranges from 30 to 800 mm/s.

- ✓ 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 SAIJ32BX35-30S FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402 Newtons of push force and 345 Newtons of pull force. At the maximum 1.0 MPa, it delivers 82 kgf.
The rear adjuster screw lets you shorten the effective stroke by up to 30mm. This creates a usable travel window from 5 to 35mm, allowing you to set the exact end position at commissioning without adding external stops.
