About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX230-100S
The AirTAC SAIJ100X230-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 3927N of push force at 0.5 MPa and features a 100mm adjustment range, creating a flexible 130-230mm usable travel window for precise end-position tuning. This model includes a SUS304 stainless steel rod for superior corrosion resistance and a magnet for CMSE or DMSE sensors.
Because the rear screw acts as a mechanical stop rather than a lock, live air is still required to hold the load. The extruded aluminum barrel provides standard ISO 15552 mounting dimensions, and the PT tapered ports ensure a tight, reliable pneumatic connection during high-force operations.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX230-100S Is Used
Product Changeover
Dial in the 130-230mm travel window on the fly to accommodate different package sizes on a packaging line without changing cylinders.
Machine Setup
Fine-tune the retract end-position during commissioning to perfectly seat heavy 3927N loads without adding external mechanical stops.
Variable End Stops
Use the 100mm adjustment range to alter the stroke endpoint for flexible manufacturing processes and varied tooling depths.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX230-100S the Right Cylinder?
Select this 100mm bore cylinder when an application requires 3927N push force at 0.5 MPa but demands variable end-stops during product changeovers, avoiding the need to physically swap out a fixed-stroke SAI cylinder. If your setup needs less force, stepping down to an 80mm bore yields 2513N; stepping up to 125mm provides 6136N. To replace an ISO 15552 cylinder, match the 100mm bore, 230mm stroke, PT ports, the -S magnet, and the SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Since the total stroke is 230mm, ensure external guiding is used to prevent excessive side-loading on the 25mm rod. For load-holding without continuous air pressure, use a SAIL or BSAI cylinder instead of relying on the adjuster.
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 SAIJ100BX230-100S FAQ
The rear adjuster acts as a mechanical stop that lets you trim the nominal 230mm stroke back by up to 100mm, providing an effective 130-230mm travel window. It only sets the travel end and does not lock the load without live air.
At 0.5 MPa, it provides 3927N of push force and 3681N of pull force. At 0.7 MPa, the push force increases to 5497N.
