About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX260-50S
The AirTAC SAIJ32X260-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 210 to 260 mm for exact end-position tuning. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered ports. An integrated magnet allows seamless position sensing with CMSE reed and DMSE solid-state switches.
This adjustable-stroke model allows you to dial in the retract end-stop during commissioning without adding external stops or swapping the cylinder. The rear adjuster acts purely as a mechanical travel stop to set the deceleration point alongside the variable air cushion; it does not hold the load without live air pressure. It uses a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX260-50S Is Used
Machine Setup Commissioning
Dial in the exact 210 to 260 mm retract position during initial machine commissioning without machining custom spacers or swapping cylinders.
Product Size Changeover
Quickly adapt the end-stop on a packaging line when product dimensions change, using the 50 mm rear adjustment to handle varying material lengths.
Variable End-Stop Forming
Provide precise mechanical stops for light-duty bending or forming tasks where the 402 N push force is sufficient and the retract position varies per part.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX260-50S the Right Cylinder?
Choose this 32 mm bore when you need 402 N of thrust at 0.5 MPa and a highly variable end-stop, stepping down from a 40 mm bore that yields 628 N if the load is lighter and space is tight. The 50 mm adjustment range is ideal for product changeovers where the precise retract position shifts frequently. For load-holding without continuous air pressure, this cylinder is insufficient because the adjuster is a stop, not a lock; you would need an external rod lock or the SAIL/BSAI series instead.
As a dimensionally interchangeable ISO 15552 profile cylinder, it matches standard mounting interface dimensions. Configuration details: 32 mm bore, 260 mm stroke, 50 mm adjustment, PT ports, SUS304 rod, and a -S magnet. Because the 260 mm stroke is substantial for a 32 mm bore, an external guide is recommended to prevent excessive side-load on the 12 mm rod and M10x1.25 thread.

- ✓ 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 SAIJ32BX260-50S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach a maximum of 82 kgf at 1.0 MPa.
The rear adjuster allows you to shorten the effective travel from the nominal 260 mm down to 210 mm, giving a 210-260 mm usable window. It functions as a mechanical stop to tune the end position and deceleration, but it does not lock the load without live air pressure.
