About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX260-20S
The AirTAC SAIJ32X260-20-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 402N of push force at 0.5 MPa and features a 260mm nominal stroke that can be fine-tuned down by up to 20mm, creating a precise 240-260mm usable travel window for commissioning flexibility.
This variant includes a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and ships with a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel retains standard sensor grooves on both sides, and the G1/8 port ensures efficient airflow for its 30-800mm/s operating speed range.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX260-20S Is Used
Product Changeover
Dial in the 240-260mm travel window during format changes on packaging lines, using the rear stopper to match new carton sizes without replacing the cylinder.
Machine Setup
Fine-tune the retract end position at commissioning to achieve exact sensor triggering, preventing hard mechanical crashes during initial machine runs.
Variable End Stops
Adjust the effective stroke dynamically on a diverter gate to handle varying product lengths on a single conveyor belt without mechanical retrofitting.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX260-20S the Right Cylinder?
Choose this 32mm bore when an application demands exact end-position tuning without swapping cylinders or adding external stops; if you need substantially more force, stepping up to the 40mm bore yields 628N push at 0.5 MPa. Because the stroke is 260mm, ensure adequate external guidance to prevent excessive side-loading on the 12mm rod. The rear adjuster acts strictly as a travel stop for deceleration, not a lock; for load-holding without live air, select an AirTAC SAIL or BSAI cylinder. To match this ISO 15552 interchangeable cylinder, specify: 32mm bore, 260mm stroke, 20mm adjustment, PT tapered port threads, SUS420J2 rod, a magnet for CMSE/DMSE switches, and a mounting choice from Basic, FA, LB, TC, FTC, TCM1, or TCM2.
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 SAIJ32AX260-20S FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. It can reach a maximum push force of 724N at 0.9 MPa.
The rear adjuster screw allows you to shorten the 260mm nominal stroke by up to 20mm, providing a usable travel window of 240-260mm. This stopper fine-tunes the end position but does not lock the load without continuous air pressure.
