About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX20-10S
The AirTAC SAIJ32X20-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 10 to 20 mm for exact end-position tuning. It delivers 402 N of push force at 0.5 MPa and includes a piston magnet for CMSE reed and DMSE electronic sensors. The rod is constructed from SUS420J2 stainless steel, and the unit uses PT tapered ports.
This adjustable-stroke design allows you to fine-tune the retract position at commissioning without swapping the cylinder or adding external stops. The rear adjuster functions strictly as a travel stop and does not hold the load without live air pressure. It supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX20-10S Is Used
Machine Changeover
Dial in the exact end-stop during product size changes on a packaging line without physically replacing the cylinder.
Clamping Positioning
Fine-tune the clamping travel window from 10 to 20 mm during commissioning to prevent over-travel on delicate workpieces.
Sensor Setup
Leverage the integrated magnet for CMSE or DMSE sensors while adjusting the rear stopper to perfect the signal trigger point.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX20-10S the Right Cylinder?
Choose this 32 mm bore when an application requires precise positioning within a 10-20 mm window, stepping up from a smaller bore if 402 N of push force at 0.5 MPa is required. If your setup demands higher force, the 40 mm bore provides 628 N at the same pressure. The adjustable stroke is ideal for machine changeovers where the end-stop varies, unlike a fixed-stroke SAI cylinder. For load-holding without live air, consider the SAIL or BSAI series. To match this ISO 15552 replacement, specify the 32 mm bore, 20 mm stroke, 10 mm adjustment, PT ports, and the -S magnet.
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 SAIJ32AX20-10S FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
The rear adjuster acts as a mechanical stop that allows you to trim the effective travel back by up to 10 mm, creating a usable stroke window of 10 to 20 mm. It functions as a travel stop, not a lock, and requires live air to hold the load.
