About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX220-75
The AirTAC SAIJ100X220-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a robust 7068N of push force at 0.9 MPa. It features a 25mm SUS304 stainless steel rod and PT G1/2 tapered ports. By turning the rear stopper screw, you can trim the effective travel into a 145-220mm adjustable window, which is ideal for dialing in exact end positions during machine commissioning without swapping out the hardware.
This adjustable-stroke design eliminates the need to bolt on external stops when product sizes change on the line. It uses a reduced mounting set that includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR options. The adjuster acts purely as a travel stop and does not hold the load without live air pressure; for true load-holding, consider the SAIL or BSAI series.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX220-75 Is Used
Variable End-Stop Tuning
Dial in the exact 145 to 220mm travel distance during machine setup to perfectly position stops for new product dimensions without changing the cylinder.
Product Changeover Systems
Quickly adjust the rear stroke stopper on a packaging line to accommodate varying package lengths on the fly, minimizing downtime between runs.
Fixture Positioning
Use the fine-tuning capability to set precise clamping locations on machining fixtures, ensuring parts are held accurately without external shims.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX220-75 the Right Cylinder?
Choose this 100mm bore when a 80mm bore (4523N push at 0.9 MPa) is insufficient, but a 125mm bore (11045N) would be excessive overkill. The 75mm adjustment range is selected over a fixed SAI cylinder when you need a highly variable end-stop for frequent product changeovers. Because the 220mm stroke is below the 300mm side-load threshold, the 25mm SUS304 rod handles the load well, though unsupported loads still require an external guide. To match this ISO 15552 interchangeable cylinder, verify your bore, 220mm stroke, 75mm adjustment, PT G1/2 ports, and mounting style. Note that since no magnet is specified, CMSE or DMSE sensors cannot be used without adding the -S option.
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 SAIJ100BX220-75 FAQ
At 0.9 MPa operating pressure, this 100mm bore cylinder provides 7068N of push force and 3681N of pull force. It reaches a maximum of 801 kgf at 1.0 MPa.
The rear adjuster screw allows you to shorten the 220mm nominal stroke by up to 75mm, creating a usable travel window of 145 to 220mm. This stopper only sets the end position; it does not lock the load without continuous air pressure.
