About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX850-10S
The AirTAC SAIJ32X850-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position. With a nominal 850mm stroke and a 10mm adjustment range, it provides an exact 840-850mm usable travel window for precise positioning. It delivers 402N of push force and 345N of pull force at 0.5MPa, making it suitable for lighter-duty work handling.
This variant includes a SUS304 stainless steel rod and a PT tapered port thread. It comes magnet-ready for AirTAC CMSE reed and DMSE electronic sensors. Because the stroke exceeds typical compact lengths, the 12mm rod diameter should be paired with an external guide to manage side loading and prevent rod bending.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX850-10S Is Used
Variable End-Stop Tuning
Dial in the exact 840-850mm retract position during machine setup or product changeover using the rear screw, avoiding the need to physically swap cylinders for minor length differences.
Light Assembly Positioning
Leverage the 402N push force at 0.5MPa to move small components into place, using the fine adjustment to guarantee consistent end-of-stroke placement.
Material Handling Stops
Adjust the stroke by up to 10mm to perfectly time the stopping point of delicate items on a conveyor line without adding bulky external mechanical stops.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX850-10S the Right Cylinder?
Choose this 32mm bore when you need precise variable end-stops during machine changeover without swapping cylinders, unlike a fixed SAI model. If your application requires more thrust, stepping up to the 40mm bore yields 628N of push force at 0.5MPa. The rear adjuster acts strictly as a travel stop, not a lock; it will not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.
To replace this ISO 15552 cylinder, match the 32mm bore, 850mm stroke, 10mm adjustment, PT port, and the -S magnet. Given the 850mm stroke, always support the load with an external guide to prevent excessive side-load wear on the rod and seals.
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 SAIJ32BX850-10S 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 can deliver up to 82kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from the nominal 850mm down to 840mm. This creates a 10mm usable travel window for fine-tuning end positions at commissioning without replacing the cylinder.
