About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX230-100
The AirTAC SAIJ100X230-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 230 mm nominal travel by up to 100 mm. This creates a highly flexible 130-230 mm usable stroke window, letting you fine-tune the retract end position during commissioning or product changeovers without swapping out the actuator.
Belonging to the 100 mm bore class, it delivers substantial thrust, providing 5497 N of push force and 3681 N of pull force at 0.7 MPa. This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads. It integrates variable air cushions at both ends to absorb kinetic energy, while the extruded aluminum barrel includes dual-side sensor grooves for straightforward position feedback.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX230-100 Is Used
Multi-Product Machining
Ideal for machining lines running varied part lengths, using the 130-230 mm travel window to quickly reposition the end stop for different workpiece sizes.
Commissioning Calibration
Perfect for initial machine setup where the exact retract distance needs slight fine-tuning against a hard stop without disassembling the actuator assembly.
Heavy-Duty Forming
Leverages the 5497 N push force at 0.7 MPa for pressing and forming operations, while the SUS304 rod withstands harsh manufacturing environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX230-100 the Right Cylinder?
Selecting this 100 mm bore actuator makes sense when your application requires high output force that smaller bores cannot provide, such as stepping up from an 80 mm cylinder (which offers 3518 N push at 0.7 MPa). The generous 100 mm adjustment range is ideal for machinery handling multiple product sizes, as the rear stopper screw allows rapid end-position tuning without adding external stops or changing the physical cylinder.
Because this is a 230 mm stroke, mounting must account for potential side loads; always use an external guide to prevent rod binding over long unsupported travels. Remember that the rear adjuster and air cushions act only as travel stops and deceleration devices—they do not hold the load without live air pressure. For true fail-safe load holding, consider the SAIL (pneumatic lock) or BSAI (clamp-lock) variants. To match this exact configuration, specify a 100 mm bore, 230 mm stroke, 100 mm adjustment, PT ports, Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings, and a SUS304 rod.
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 SAIJ100BX230-100 FAQ
It features a rear stopper screw that allows you to mechanically shorten the effective stroke by up to 100 mm. This provides a usable travel window of 130 to 230 mm, enabling precise end-position tuning without replacing the cylinder or adding external stops.
At a 0.7 MPa operating pressure, the 100 mm bore generates 5497 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.
