About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX30-30S
The AirTAC SAIJ32X30-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the end position at commissioning. It provides a usable travel window of 0-30 mm, giving you full control over the 30 mm nominal stroke without needing external stops. The 32 mm bore delivers 402 N of push force at 0.5 MPa, making it suitable for light-duty handling tasks.
This variant features a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. It uses a G1/8 port and offers adjustable air cushions at both ends to decelerate the load. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX30-30S Is Used
Precision End-Position Tuning
Dial in the exact retract distance during machine commissioning without swapping out the entire cylinder or adding external stopper blocks.
Product-Size Changeover
Quickly adapt the 0-30 mm travel window on automated lines when handling slightly different product dimensions on the fly.
Light-Duty Positioning
Leverage the 402 N push force and compact 32 mm profile to move small components accurately within tight machinery layouts.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX30-30S the Right Cylinder?
Choose this 32 mm bore cylinder when you need precise variable end-stops for product-size changeovers on a line, stepping up to a 40 mm bore yields 628 N of push force at 0.5 MPa if your payload increases. The rear adjuster acts strictly as a travel stop to set the retract end, not a lock; it cannot hold the load without live air. For load-holding without pressure, consider the SAIL or BSAI series. As a dimensionally interchangeable ISO 15552 cylinder, match your replacement by confirming the 30 mm stroke, 30 mm adjustment, PT tapered port threads, and the -S magnet.

- ✓ 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 SAIJ32AX30-30S FAQ
At 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 up to 724 N of push force at 0.9 MPa.
The rear adjusting screw acts as a mechanical stop that lets you trim the effective stroke back by up to 30 mm. Since the nominal stroke is 30 mm, you get a 0-30 mm usable travel window to fine-tune the end position without replacing the cylinder.
