About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX70-50S
The AirTAC SAIJ32X70-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 20-70 mm, allowing you to dial back the 70 mm nominal stroke by up to 50 mm during commissioning. Delivering 402 N of push force at 0.5 MPa, it suits light-duty positioning tasks.
This variant includes a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and a magnet for CMSE reed or DMSE electronic sensors. It uses a PT tapered port and omits the FB, CA, CB, and CR mounts, offering Basic, FA, LB, TC, FTC, TCM1, and TCM2 interfaces.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX70-50S Is Used
End-Position Tuning
Fine-tune the 20-70 mm travel window during machine commissioning to hit exact retract positions without swapping cylinders.
Product Changeover
Quickly adjust the retract stop on packaging lines when handling different product sizes, avoiding mechanical rebuilds.
Light-Force Positioning
Leverage the 402 N push force at 0.5 MPa for precise, low-impact positioning of small components on an assembly line.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX70-50S the Right Cylinder?
Choose this 32 mm bore if your application requires 402 N of push force at 0.5 MPa; step down to a 25 mm bore if your load is lighter, or up to a 40 mm bore (628 N) for heavier demands. The adjustable stroke is ideal for product changeovers, letting you fine-tune the retract end position without adding external stops or swapping a fixed SAI cylinder.
The rear adjuster acts as a travel stop, not a lock. It cannot hold a load without live air pressure. For fail-safe load holding, consider the SAIL or BSAI series. The 12 mm rod and M10x1.25 thread handle moderate side loads, but long unsupported strokes still require an external guide.
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.
