About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX210-20S
The AirTAC SAIJ32X210-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the effective travel down from 210 mm to a 190-210 mm window. It delivers 402 N of push force at 0.5 MPa and features a SUS304 stainless steel rod for corrosion resistance. The integrated magnet supports position sensing.
This adjustable-stroke design lets you dial in the exact retract end-position during commissioning without swapping hardware. The rear screw acts purely as a travel stop for the air cushion and cannot hold the load without live air. It uses a PT G1/8 port and shares the standard ISO 15552 footprint, omitting FB, CA, CB, and CR mounts.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX210-20S Is Used
Machine Setup
Fine-tune the 190-210 mm travel window during commissioning to hit exact end positions without adding external stoppers.
Product Changeover
Quickly adjust the retract stop for varying product sizes on a conveyor line without changing the cylinder.
End-Position Trimming
Use the rear screw to trim the stroke by up to 20 mm, compensating for mechanical wear or sensor drift over time.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX210-20S the Right Cylinder?
Choose this 32 mm bore when your application requires less force than the 40 mm bore (628 N push at 0.5 MPa) but needs precise end-stop tuning. The SUS304 rod and M10x1.25 thread handle moderate side loads, but because the stroke is 210 mm, you should use an external guide to prevent rod binding. For load-holding without live air, select the SAIL or BSAI series instead of relying on the adjuster. To match this ISO 15552 cylinder, specify the 32 mm bore, 210 mm stroke, 20 mm adjustment, PT port, and -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 SAIJ32BX210-20S FAQ
At 0.5 MPa, it provides 402 N of push force and 345 N of pull force. The maximum thrust is 82 kgf at 1.0 MPa.
The rear adjuster lets you shorten the 210 mm nominal stroke by up to 20 mm, creating a 190-210 mm travel window. It acts as a stop and does not lock the load.
