About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX450-10S
The AirTAC SAIJ32X450-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel end during commissioning. Based on the 450 mm nominal stroke and the 10 mm adjustment code, this SKU yields a 440-450 mm usable travel window without requiring external stops. It delivers a 0.5 MPa push force of 402 N and a pull force of 345 N.
This specific configuration includes a SUS304 stainless steel rod (option B) for superior corrosion resistance and uses PT tapered ports. The extruded aluminum barrel includes sensor grooves on both sides, and because this is the -S variant, it carries a magnet ready for AirTAC CMSE reed and DMSE electronic solid-state switches. The standard adjustable air cushions at both ends decelerate the load, but the rear adjuster acts strictly as a travel stop, not a lock.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX450-10S Is Used
Machine Changeover
Dial in the 440-450 mm end position precisely during product size transitions without adding external stopper blocks.
End-Position Tuning
Fine-tune the retract travel end at commissioning to absorb mechanical tolerances in your fixture layout.
Variable Stops
Adjust the stroke on the fly for conveyor diverters or handling lines that process multiple package lengths.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX450-10S the Right Cylinder?
Choose this 32 mm bore when your application requires less than the 628 N push force offered by the 40 mm bore at 0.5 MPa, but needs more precision than smaller profiles. An adjustable stroke is ideal for machine setup and product changeovers, letting you dial in the exact end position without swapping the cylinder. For load-holding without live air pressure, note that this cylinder cannot hold its position; you should look at the SAIL or BSAI series, or use an external rod lock.
Because the stroke is 450 mm, the 12 mm diameter rod and M10x1.25 rod thread will experience higher side-load stresses if the load is unsupported. An external guide is strongly recommended to prevent binding over this long travel. This SAIJ model is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).

- ✓ 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 SAIJ32BX450-10S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides a push force of 402 N and a pull force of 345 N. The maximum push force is 724 N at 0.9 MPa.
The rear adjuster acts as an external stopper that lets you shorten the effective travel by up to 10 mm. For this 450 mm stroke model, it creates a 440-450 mm usable travel window for fine-tuning at commissioning.
