About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX70-10S
The AirTAC SAIJ32X70-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 60-70 mm usable travel window, letting you trim the 70 mm nominal stroke by up to 10 mm during commissioning without swapping the cylinder or adding external stops. It delivers 402 N of push force at 0.5 MPa, making it ideal for lighter-duty precision tasks.
This variant uses a SUS304 stainless steel rod for corrosion resistance and includes a magnet (-S) for position sensing with AirTAC CMSE reed or DMSE electronic switches. It features PT tapered port threads (G1/8) and variable air cushions at both ends. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX70-10S Is Used
Machine Setup Changeover
Fine-tune the 60-70 mm travel window during product line changeovers to dial in exact end positions without disassembling the machinery.
Variable End-Stop Positioning
Use the rear adjuster to set precise retract stops for light-duty machining or clamping tasks where a 402 N thrust is sufficient.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod for positioning tasks in washdown or corrosive environments while maintaining ISO 15552 footprint compatibility.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX70-10S the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N push force at 0.5 MPa. If you need less force, step down to a 25 mm bore, or step up to a 40 mm bore (628 N at 0.5 MPa) for heavier loads. The adjustable stroke is perfect for machine setups requiring variable end-stops or product-size changeovers, whereas a fixed SAI cylinder locks you into one position. For true load-holding without live air, select a SAIL or BSAI cylinder instead. To replace an ISO 15552 cylinder, match the 32 mm bore, 70 mm stroke, 10 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 SAIJ32BX70-10S 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 up to 724 N of push force at 0.9 MPa.
The rear adjuster screw allows you to shorten the 70 mm nominal stroke by up to 10 mm, creating a 60-70 mm usable travel window. This stopper only sets the end position; it does not lock the load without continuous air pressure.
