About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX325-20
The AirTAC SAIJ100X325-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 325 mm travel by up to 20 mm. This creates a precise 305-325 mm usable window, enabling fine end-position tuning at commissioning without swapping the cylinder or bolting on external stops. It delivers substantial thrust, generating 7068 N of push force at 0.9 MPa.
This unit features a SUS304 stainless steel rod for superior corrosion resistance and carries a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if a magnet is added later. Because the stroke exceeds 300 mm, the 25 mm rod diameter should be paired with an external guide to handle side loads effectively.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX325-20 Is Used
Product Changeovers
Dial in the 305-325 mm travel window during format size changes on packaging lines without replacing the actuator.
Commissioning Calibration
Fine-tune the exact end-stop position during machine setup to prevent mechanical crashes and optimize the process.
Heavy Workpiece Handling
Leverage the 7068 N push force at 0.9 MPa to shift heavy industrial pallets or cast parts into machining fixtures.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX325-20 the Right Cylinder?
Choose this 100 mm bore when you need heavy thrust that smaller neighbors cannot provide, such as the 80 mm bore which offers 4523 N push force at 0.9 MPa. The adjustable stroke is ideal for product-size changeovers on a line, letting you set a new variable end-stop quickly. Remember that the rear adjuster acts only as a travel stop, not a lock; the SAIJ does not hold loads without live air, so look to the SAIL or BSAI series if load-holding is required.
For a direct ISO 15552 replacement match, specify a 100 mm bore, 325 mm stroke, 20 mm adjustment, PT port thread, and your required mounting style. SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.
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 SAIJ100BX325-20 FAQ
At an operating pressure of 0.9 MPa, this 100 mm bore cylinder provides a push force of 7068 N and a pull force of 3681 N. It reaches a maximum thrust of 801 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop that trims the effective travel. For this 325 mm nominal stroke model, it provides a usable 305-325 mm travel window, allowing precise end-position tuning without adding external stops.
