About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X110-20S
The AirTAC SAIJ32X110-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 90-110 mm from its 110 mm nominal stroke. It delivers 402 N of push force at 0.5 MPa and features a carbon steel rod with an M10x1.25 thread. This magnetic version includes a piston magnet for position sensing via AirTAC CMSE reed or DMSE electronic switches fitted into the dual-side sensor grooves.
Instead of adding external stops during commissioning, the rear adjusting screw allows fine end-position tuning without swapping the cylinder. It uses a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. The rear adjuster acts purely as a travel stop to set deceleration, not as a load-holding lock.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X110-20S Is Used
End-Position Tuning
Dial in the exact retract distance within the 90-110 mm window during machine setup without machining new hard stops.
Product Changeover
Quickly adapt the cylinder travel on a packaging line when switching to a different sized carton or fixture.
Sensor Equipped Sorting
Leverage the -S magnet and dual sensor grooves to confirm end-of-stroke signals while adjusting the travel limit.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X110-20S the Right Cylinder?
Choose this 32 mm bore when your application requires around 402 N of push force at 0.5 MPa, stepping down from a 40 mm bore that yields 628 N. The adjustable stroke is ideal for product-size changeovers where the exact end position needs on-the-fly tuning. For load-holding without live air pressure, select a SAIL or BSAI cylinder instead, as the SAIJ adjuster is only a stop.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 110 mm stroke, 20 mm adjustment range, PT tapered port threads, and the -S magnet option. Since the 110 mm stroke is relatively short, side-load risks are minimal, but always ensure the M10x1.25 rod thread is properly aligned to prevent binding.
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 SAIJ32X110-20S 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 a maximum push force of 724 N at 0.9 MPa.
The rear adjusting screw acts as an external stopper that lets you shorten the effective stroke by up to 20 mm. This creates a usable travel window of 90 to 110 mm, allowing fine-tuning of the end position at commissioning without replacing the cylinder.
