About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX230-30S
The AirTAC SAIJ100X230-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 200 to 230 mm. Delivering a robust 3927 N of push force at 0.5 MPa, it handles heavy-duty positioning with ease. The extruded aluminum barrel features sensor grooves on both sides, and because this unit includes the -S magnet, it directly supports CMSE reed and DMSE solid-state switches for precise end-of-stroke detection.
This model features a SUS304 stainless steel rod (code B) paired with a 25 mm rod diameter and M20x1.5 thread, offering high corrosion resistance and excellent side-load capacity. The rear adjustment screw allows you to fine-tune the retract end position during commissioning or product changeovers without swapping out the cylinder or adding external stops. It utilizes a PT G1/2 port and includes variable air cushions at both ends to manage impact deceleration smoothly.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX230-30S Is Used
Product Changeovers
Quickly dial in the retract position by up to 30 mm when switching between product sizes on a packaging line, avoiding physical cylinder swaps.
End-Stop Calibration
Fine-tune the final resting position of heavy actuators during machine commissioning to achieve exact mechanical alignment.
Heavy Forming Presses
Leverage the 3927 N push force at 0.5 MPa to securely press components into place while using the adjuster to limit over-travel.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX230-30S the Right Cylinder?
Selecting this 100 mm bore makes sense when you need substantial thrust—such as the 3927 N push force at 0.5 MPa—that a smaller 80 mm bore (2513 N) cannot provide, without stepping up to a massive 125 mm unit. The adjustable 30 mm stroke window is specifically chosen for machines requiring variable end-stops for different product sizes, eliminating the need to re-pneumatic lines for a fixed-stroke SAI cylinder. To match this ISO 15552 footprint, specify the 100 mm bore, 230 mm stroke, PT G1/2 port, and the -S magnet. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Because the stroke is 230 mm, an external guide is recommended to prevent rod sag and premature seal wear over long unsupported extensions. Remember that the rear adjuster and air cushions only set the travel end and deceleration; they do not hold the load without live air pressure. For fail-safe load holding, consider the SAIL (air-released lock) or BSAI (clamp-lock) series instead.
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 SAIJ100BX230-30S FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 30 mm. This creates a 200-230 mm usable travel window for fine-tuning the end position without replacing the cylinder.
