About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX450-10
The AirTAC SAIJ100X450-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 440 to 450 mm usable travel window, letting you dial back the end position by up to 10 mm during commissioning. The 100 mm bore yields 3927 N of push force at 0.5 MPa and 5497 N at 0.7 MPa. This variant features a SUS304 stainless steel rod for corrosion resistance and uses PT tapered port threads.
The rear adjuster acts purely as a travel stop for end-position tuning, meaning it will not hold a load without live air pressure. For position holding without continuous air, an external SAIL or BSAI lock is required. This extruded aluminum profile cylinder includes sensor grooves on both sides, and its mounting options span Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX450-10 Is Used
Machine Setup Changeover
Fine-tune the 440 to 450 mm travel end position during product line changeovers without physically replacing the cylinder.
Variable End Stops
Dial in the exact retract distance by up to 10 mm to accommodate varying material thicknesses on the fly.
Heavy Assembly Pressing
Leverage 5497 N of push force at 0.7 MPa to seat heavy components securely during automated assembly operations.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX450-10 the Right Cylinder?
Choose this 100 mm bore when an 80 mm bore falls short, as the 80 mm delivers only 2513 N of push force at 0.5 MPa compared to this model's 3927 N. The adjustable stroke is ideal for machine setups requiring variable end stops or product-size changeovers without swapping hardware. Since the 450 mm stroke is substantial, ensure an external guide supports the load to prevent excessive side-loading on the M20x1.5 rod thread. To match this cylinder for an ISO 15552 replacement, verify the 100 mm bore, 450 mm stroke, 10 mm adjustment, PT G1/2 port, and mounting style. Note that because no magnet is specified, CMSE or DMSE sensors cannot be used.
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 SAIJ100BX450-10 FAQ
At 0.5 MPa it provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw lets you trim the 450 mm nominal stroke back by up to 10 mm, creating a 440 to 450 mm usable travel window for precise end-position tuning.
