About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX275-10
The AirTAC SAIJ100X275-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 265 to 275 mm usable travel window, allowing you to dial in the retract end-position precisely during commissioning. Delivering 3927 N of push force at 0.5 MPa, it handles substantial workloads while maintaining a standard extruded aluminum barrel with sensor grooves on both sides.
This variant is configured with a SUS304 stainless steel rod (option B) for superior corrosion resistance and a PT tapered port thread. The 25 mm rod diameter and M20x1.5 rod thread provide excellent rigidity, though with a 275 mm stroke, supporting the load with an external guide is recommended to prevent excessive side-loading. The rear adjuster acts purely as a mechanical stop to set the travel end and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX275-10 Is Used
Machine Setup Commissioning
Fine-tune the 265-275 mm travel window during initial machine build to perfectly dial in the retract position without adding external stopper blocks.
Product Changeover
Quickly adjust the end-stop by up to 10 mm when running a new product size on the line, minimizing downtime between production batches.
Heavy Material Handling
Leverage the 3927 N push force at 0.5 MPa to move heavy pallets or pusher assemblies, using the adjustable stroke to accommodate varying load widths.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX275-10 the Right Cylinder?
Choose this 100 mm bore when you need more force than the 80 mm version (which yields 2513 N at 0.5 MPa) but do not require the heavy 125 mm class. The integrated 10 mm stroke adjustment is selected over a fixed SAI cylinder when a process requires variable end-stops or fine-tuning during product changeover, eliminating the need to swap out the entire actuator. To replace an ISO 15552 cylinder, match the 100 mm bore, 275 mm stroke, 10 mm adjust, PT G1/2 port, and the desired mounting set.
For load-holding applications without continuous compressed air, this cylinder is not suitable as the adjuster is only a stop. In such cases, consider the SAIL (air-released lock) or BSAI (clamp-lock) series instead. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the 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 SAIJ100BX275-10 FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 801 kgf of push force.
The rear adjuster screw allows you to mechanically shorten the effective travel from the nominal 275 mm down to 265 mm. This creates a 10 mm adjustable window for setting the retract end-position without replacing the cylinder.
