About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX850-30
The AirTAC SAIJ32X850-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 850mm travel with a 30mm external adjustment range, yielding a usable 820-850mm end-position window for precise setup tuning. Equipped with a SUS420J2 stainless steel rod (code A), it delivers 402N of push force at 0.5MPa and operates at speeds between 30 and 800mm/s.
This model uses a PT tapered G1/8 port and includes variable air cushions at both ends to manage kinetic energy. The extruded aluminum barrel features sensor grooves on both sides, allowing you to mount position switches if needed later. The rear stopper acts solely as a travel end deceleration device, not a load lock, meaning live air pressure is required to hold position.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX850-30 Is Used
Product Changeover
Dial in the 820-850mm retract position during format size changes on packaging lines without replacing the actuator.
End-Stop Tuning
Fine-tune the final end position during machine commissioning to compensate for mechanical tolerance stack-up.
Variable Ejector
Adjust the pusher stroke length on the fly to eject different sized parts from a moving conveyor belt.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX850-30 the Right Cylinder?
Choose this 32mm bore when your application requires 402N push force at 0.5MPa, and stepping up to a 40mm bore (628N) would be excessive overkill. The 30mm adjustable window is ideal for product-size changeovers, letting you fine-tune the retract end without swapping cylinders or adding external stops. For load-holding without continuous air pressure, consider the SAIL or BSAI series instead.
With an 850mm stroke on a 12mm rod, this cylinder is susceptible to side-loading; an external guide rail is strongly recommended to prevent premature seal wear. Replacement is straightforward: match the 32mm bore, 850mm stroke, 30mm adjustment, PT G1/8 port, and basic mounting footprint to any dimensionally interchangeable ISO 15552 unit.
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 SAIJ32AX850-30 FAQ
At 0.5MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At the maximum 1.0MPa pressure, it delivers up to 82kgf.
The rear adjuster screw lets you shorten the effective travel from 850mm down to 820mm. It acts as a mechanical stop to fine-tune the end position, but it is not a lock and cannot hold the load without live air pressure.
