About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX220-100
The AirTAC SAIJ100X220-100 is a double-acting ISO 15552 profile cylinder featuring a rear mechanical adjuster that allows you to trim the effective stroke by up to 100 mm. This creates a highly flexible 120 to 220 mm usable travel window, enabling precise end-position tuning during commissioning without adding external stops or swapping the unit. It delivers 3927 N of push force at 0.5 MPa and reaches a maximum of 801 kgf at 1.0 MPa.
This specific configuration features a SUS304 stainless steel rod (option B) for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this unit is specified without a magnet. Mounting options utilize the reduced SAIJ set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX220-100 Is Used
Product Changeover
Dial in the 120-220 mm travel window instantly when switching line formats, avoiding physical hardware swaps.
End-Stop Tuning
Fine-tune the retract position during machine commissioning to achieve exact dimensional accuracy.
High-Force Positioning
Leverage 3927 N of push force at 0.5 MPa to move heavy pallets while adjusting the stroke limit on the fly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX220-100 the Right Cylinder?
Choose this 100 mm bore if your application requires substantial thrust—stepping down to an 80 mm bore drops the 0.5 MPa push force to 2513 N, while a 125 mm bore increases it to 6136 N. An adjustable-stroke cylinder is selected over a fixed SAI model when you need variable end-stops for machine setup or product changeovers. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, select an SAIL or BSAI lock cylinder.
Because the 220 mm stroke is below the 300 mm side-load threshold, the robust 25 mm rod and M20x1.5 rod thread handle standard lateral forces well without requiring an external guide. When replacing an ISO 15552 cylinder, match the 100 mm bore, 220 mm stroke, 100 mm adjustment, PT G1/2 ports, and the appropriate mounting bracket.
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 SAIJ100BX220-100 FAQ
The rear adjusting screw acts as a mechanical stopper that shortens the retract travel by up to 100 mm. This gives you a usable stroke window of 120 to 220 mm, allowing you to set the exact end position without replacing the cylinder.
At 0.5 MPa operating pressure, it provides 3927 N of push force and 3681 N of pull force. At the maximum 1.0 MPa pressure, the push force increases to 801 kgf.
