About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX260-100S
The AirTAC SAIJ32X260-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims travel by up to 100 mm. This creates a highly versatile 160 to 260 mm usable stroke window, letting you fine-tune end positions during commissioning without swapping hardware. It delivers 402 N of push force at 0.5 MPa and uses a PT G1/8 port.
Built with a SUS420J2 stainless steel rod and an integrated magnet, this unit supports CMSE reed and DMSE electronic sensors via dual-side barrel grooves. The SAIJ mounting set omits FB, CA, CB, and CR brackets, focusing on Basic, FA, LB, TC, FTC, TCM1, and TCM2 options for streamlined machine integration.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX260-100S Is Used
Variable End Stops
Dial in the exact 160 to 260 mm travel needed for different product sizes without adding external physical stops to the machine frame.
Machine Changeover
Quickly reposition the retract end-point during format changes on a packaging line using the rear adjustment screw.
Commissioning Calibration
Fine-tune the final end position during setup to absorb mechanical tolerances without machining or replacing spacers.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX260-100S the Right Cylinder?
Choose this 32 mm bore when 402 N of thrust at 0.5 MPa is sufficient, stepping up to the 40 mm bore if you need 628 N. The 100 mm adjustment range is perfect for product changeovers requiring variable end stops, unlike a fixed-stroke SAI cylinder. To match this ISO 15552 replacement, specify bore 32, stroke 260, adjust 100, PT G1/8 port, and the -S magnet. Since the 260 mm stroke exceeds 300 mm? No, but still, for any extended travel, ensure external guides manage side loads. The rear adjuster acts only as a travel stop, not a lock; for load-holding without live air, use SAIL or BSAI cylinders.
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 SAIJ32AX260-100S FAQ
This 32 mm bore cylinder provides 402 N of push thrust and 345 N of pull thrust at 0.5 MPa, scaling up to 724 N push at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop that shortens the nominal 260 mm stroke, giving you a usable travel window between 160 and 260 mm. It does not lock the load without live air pressure.
