Airtac Adjustable Cylinder SAIJ32 SAIJ32X1000-20S
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32X1000-20S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 1000mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X1000-20S
The AirTAC SAIJ32X1000-20-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 980 to 1000 mm usable travel window, allowing you to dial back the end-of-stroke position by up to 20 mm during commissioning. Equipped with a -S magnet, it integrates seamlessly with AirTAC CMSE reed and DMSE electronic sensors housed in the dual-side barrel grooves.
Delivering 402 N of push force at 0.5 MPa, this 32 mm bore unit uses a G1/8 port and a 12 mm carbon steel rod with an M10x1.25 thread. Because the 1000 mm stroke exceeds the standard 1000 mm maximum, this is a made-to-order non-standard stroke variant. The rear adjuster functions strictly as a travel stop for fine-tuning, not as a load-holding lock.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X1000-20S Is Used
End-Position Tuning
Dial in the exact retract distance within the 980-1000 mm window during machine setup to compensate for mechanical tolerances.
Product Changeover
Quickly adjust the stroke stop by up to 20 mm when switching between product sizes on a packaging line without swapping cylinders.
Long-Stroke Indexing
Use the 1000 mm travel for pushing materials down a conveyor, relying on the rear stop to set the final rest position.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X1000-20S the Right Cylinder?
Choose this adjustable model when your application requires exact end-position tuning or frequent product changeovers without adding external stops. If you need higher force, stepping up to a 40 mm bore yields 628 N at 0.5 MPa. Unlike fixed-stroke SAI cylinders, the SAIJ rear screw allows on-the-fly adjustments. For load-holding without live air pressure, consider an AirTAC SAIL pneumatic lock, a BSAI clamp-lock cylinder, or an external rod lock.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 1000 mm nominal stroke, 20 mm adjustment range, PT tapered port threads, and the -S magnet option. Due to the 1000 mm stroke, the 12 mm rod is highly susceptible to side-loading; an external guide is mandatory to prevent premature seal wear. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and 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 SAIJ32X1000-20S FAQ
At a 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 82 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from 1000 mm down to 980 mm. It is a travel stop for fine-tuning, not a lock, and cannot hold a load without continuous air pressure.
