About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX270-20S
The AirTAC SAIJ32X270-20-S is a double-acting, adjustable-stroke ISO 15552 profile cylinder. A rear stopper screw lets you fine-tune the end position at commissioning, creating a usable travel window of 250 to 270 mm without adding external stops. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This SKU features a SUS304 stainless steel rod for corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel provides sensor grooves on both sides. It uses a G1/8 port and supports speeds from 30 to 800 mm/s.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX270-20S Is Used
Machine Changeover
Dial in the exact end position within the 250-270 mm window during product size changes without swapping cylinders.
Variable End Stops
Fine-tune the retract stroke on packaging equipment to accommodate different material lengths on the fly.
Corrosive Environments
Leverage the SUS304 stainless steel rod for reliable actuation in washdown or lightly corrosive testing environments.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX270-20S the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N push force at 0.5 MPa. If your process needs less force, dropping to a smaller bore changes the footprint; if you need significantly more power, stepping up to the 40 mm bore provides 628 N. The adjustable stroke is ideal for product changeovers where the exact end position varies by up to 20 mm, replacing the need to swap a fixed-stroke SAI cylinder.
This model uses PT tapered ports and a SUS304 rod. The mounting interface includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options. Because the stroke is 270 mm, ensure an external guide supports any side loads to prevent rod binding. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air pressure. For load-holding without pressure, use an SAIL or BSAI cylinder.
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 SAIJ32BX270-20S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 82 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the nominal 270 mm down to 250 mm. It only sets the end position and does not lock the load without live air pressure.
