About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X275-50
The AirTAC SAIJ32X275-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 225-275 mm, allowing you to dial back the 275 mm nominal stroke by up to 50 mm during machine commissioning. Delivering 402 N of push force at 0.5 MPa, it uses a G1/8 port and a 12 mm carbon steel rod.
This adjustable-stroke design eliminates the need to swap cylinders or bolt on external stops when fine-tuning retract end-positions. The rear adjuster functions purely as a travel stop, not a lock, meaning it will not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X275-50 Is Used
End-Stop Tuning
Dial in the exact retract position within the 225-275 mm window during machine setup without changing the physical cylinder.
Product Changeover
Quickly adapt the stroke length by up to 50 mm when switching product sizes on a packaging line.
Fixture Positioning
Fine-tune clamping locations precisely at commissioning, relying on the rear stopper rather than adding external hardware.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X275-50 the Right Cylinder?
Choose this 32 mm bore when you need precise end-position tuning without external hardware; if your application requires less force, stepping down is not an option from this size, but stepping up to a 40 mm bore yields 628 N of push at 0.5 MPa. The 275 mm stroke exceeds the 300 mm threshold, so an external guide is recommended to prevent side-load damage to the 12 mm rod. To match this ISO 15552 cylinder, specify the PT port thread, carbon steel rod, and the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting set.
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 SAIJ32X275-50 FAQ
At an operating pressure of 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum pressure of 1.0 MPa, it delivers up to 82 kgf.
The rear adjuster screw acts as a mechanical stop that shortens the effective travel from the 275 mm nominal stroke down to as little as 225 mm. It only sets the end position and does not lock the load without live air pressure.
