About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X115-50S
The AirTAC SAIJ32X115-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window from 65 to 115 mm. Delivering 402 N of push force at 0.5 MPa, it is built with a carbon steel rod and a PT tapered port.
Because it includes a magnet for position sensing, this unit supports AirTAC CMSE reed and DMSE electronic solid-state switches. The extruded aluminum barrel provides sensor grooves on both sides, and the rear stopper acts purely as a travel end deceleration device, not a load-holding lock.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X115-50S Is Used
Machine Setup & Changeover
Dial in the exact end-of-stroke position during line changeovers using the 50 mm rear adjustment window, avoiding the need to physically swap out the entire actuator.
Variable End-Stop Positioning
Ideal for testing and assembly fixtures where the effective travel must be trimmed back repeatedly within the 65 to 115 mm range to accommodate different part lengths.
Sensor-Equisted Testing
The integrated magnet works with CMSE and DMSE sensors to confirm end-of-stroke reach across the adjustable travel window in automated validation rigs.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X115-50S the Right Cylinder?
Choose this 32 mm bore if your application requires 402 N of push force at 0.5 MPa and highly variable end-position tuning. The 50 mm adjustment range is ideal for product changeovers, letting you dial back the stroke without swapping cylinders or adding external stops. If you need less force, stepping down is not an option in this series, but stepping up to a 40 mm bore yields 628 N.
When ordering an ISO 15552 replacement, match the 115 mm stroke, 50 mm adjuster, PT port thread, and the -S magnet option. For load-holding without live air pressure, this cylinder is insufficient since the adjuster is only a stop; consider the SAIL or BSAI series instead. For any stroke of 300 mm or more, always add an external guide to prevent side-load damage.
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 SAIJ32X115-50S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. The maximum thrust is 82 kgf at 1.0 MPa.
The rear adjuster screw lets you shorten the nominal 115 mm stroke by up to 50 mm, creating a usable travel window of 65 to 115 mm. The adjuster acts as a mechanical stop to tune the end position and does not lock or hold the load without live air.
