About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX220-40
The AirTAC SAIJ100X220-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 180-220mm usable travel window, allowing you to dial back the nominal 220mm stroke by up to 40mm during commissioning without adding external stops. Delivering a robust 7068N of push force at 0.9 MPa, it is built for demanding industrial positioning.
This configuration uses a SUS304 stainless steel rod for superior corrosion resistance and includes PT tapered ports. The extruded aluminum barrel features sensor grooves on both sides, supporting CMSE reed and DMSE electronic sensors if a magnet is added later. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX220-40 Is Used
Machine Setup Tuning
Fine-tune the 180-220mm travel window during initial commissioning to perfectly align heavy press components without machining custom spacers.
Product Changeover
Quickly adapt the end-stop position on a conveyor line when switching between different product sizes, reducing downtime between runs.
Heavy Material Handling
Leverage the 7068N push force at 0.9 MPa to move heavy pallets or workpieces, using the adjuster to set precise stopping distances.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX220-40 the Right Cylinder?
Choose this 100mm bore cylinder when you need higher force than the 80mm version (4523N push at 0.5 MPa) but less bulk than the 125mm bore (6136N push at 0.5 MPa). The adjustable stroke is ideal for machine setups requiring variable end-stops or product changeovers. Because the 220mm stroke is relatively long, ensure you use an external guide to prevent excessive side-loading on the rod.
The rear adjuster acts only as a travel stop to fine-tune deceleration alongside the adjustable air cushions; it does not hold the load without live air. For true load-holding without pressure, select a SAIL or BSAI cylinder. This model is dimensionally interchangeable per ISO 15552 and uses a G1/2 port.
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 SAIJ100 Adjustable Cylinder SAIJ100BX220-40 FAQ
At an operating pressure of 0.9 MPa, this 100mm bore cylinder provides a push force of 7068N and a pull force of 3681N. At 0.5 MPa, the push force is 3927N.
The rear adjusting screw allows you to shorten the effective stroke from the nominal 220mm down to 180mm. This provides a 180-220mm adjustable travel window, letting you set the exact end position at commissioning without replacing the cylinder.
